Common Thermocouple Type:s

-------r'

Types; B, E, Jo K, Nr"R, Sn T, C tWS

tt)

The Type B thermocouple is composed of a platinum-30% rhodium (+) wire versus a platinum-6% (-) wire. This /type of thermocouple can be used in oxidizing or inert atmospheres with a service temperature range between 870 and 1700"C (1 000 to 3100'F). They should never be used in reducing atmospheres. Vacuum applications re possible for short periods of time. As with all platinum type thermocouples, they should always be protected ith a ceramic protection tube. Alumina insulators and protection tubes are preferred to prevent silica contamina- tion from Mullite ceramics. ln most situations platinum thermocouples should not be placed in any type of metal tube. ln high temperature applications Type B thermocouples are less susceptible to grain growth and calibration drifts than R and S type ther- mocouples. The Type E thermocouple is composed of a nickel-10% chromium (+) versus a nickel-45% copper (-) wire. This type of thermocouple can be used in oxidizing or inert atmospheres with a service temperature range of -200 to 900'C G330 to 1600"F). The Type E thermocouple can be used successfully in subzero applications due to high corrosion resistance to high moisture environments. Out of all of the different types of thermocouples, the Type E s the highest EMF output per degree. The Type J thermocouple is composed of an iron (+) wire versus a nickel-4S% copper (-) wire. This type of thermo- couple should be used in oxidizing, reducing, vacuum or inert atmospheres with a service temperature range between 0 and 760'C (32 to 1400'F). lf the thermocouple is being used over 540"C (1000'F) an 8 gauge wire should be used due to rapid oxidation of the iron (+) wire. Type J thermocouples should not be used in sulfurous applications above 540'C (1000'F). The negative element, or JN, of a Type J thermocouple can be described by any of the following names: Constantan, ThermoKanthal -JNs, HAI-JN1, Cuprona, or, Advances. The positive element, or JP, of a Type J thermocou- The Type K thermocouple is composed of a Nickel-10% chromium (+) wire versus a nickel-S% aluminum and silicon C) wire. This type of thermocouple should only be used in oxidizing or inert atmospheres with a service temperature range between -200 and 1260"C (-330 to 2300'F). They are most widely used at tempera- tures above 540'C (1000"F) due to superior oxidation resistance in comparison to Types E, T, or J. There are some conditions which should be avoided when using Type K thermocouples. Vacuum applications should not use Type K due to vaporization of chromium in the positive element. Type K thermocouples should not be used in Sulfurous environments since both elements will rapidly corrode and the negative element will eventually fail mechanically due to becoming brit- tle. Reducing atmospheres should also be avoided. Low oxygen levels can cause the Green-Rot phenomenon in which the chromium in the elements starts to oxidize causing large neg- ative drifts in calibration. Green-Rot is most pronounced when the thermocouples are used between 815 to 1040'C (1500 to 1900'F). ln order to avoid this problem, large lD protection tubes should be used to maximize internal air circulation or the installation of an oxy- gen getter in the bottom of the protection tube. lf Green-Rot is a serious problem, Type N thermocouples should be installed. The negative element, or KN, of a Type K thermocouple can be described by any of the following names: Alumel2, HAI-KN1, ThermoKanthal-KNs, T-2s, Nickel-silicon, or Nial+. The positive element, or KP, of a Type K thermocouple can be described by the fol- lowing names: Chromel2, Tophel+, ThermoKanthal-KPs, Nickel-chrome, T-13, or HAI-KP1. ple can be described by any of the following names: ThermoKanthal-JPs, lron, HAI-JP1 The Type N thermocouple is composed of a nickel-147o chromium-1%/o silicon (+) wire versus anickel4/2"/o silicon-1/10% magnesium (-) wire. The Type N thermocouple is the newest addition to the ISA family. lt was eveloped to be used under the same conditions as a Type K. Type N should be used in oxidizing or inert mospheres with a service temperature range between -200 and 1260"C (-330 to 2300'F). The addition of sil- n and chromium makes this type of thermocouple more resistant to Green-Rot and less drifting when com- pared to a Type K. The negative element, or NN, of a Type N thermocouple can be described by any of the following names: Nisil, nickel-silicon, or, HAI-NN1. The positive element, or NP, of a Type N thermocouple can be described by any of the following names: Nicrosil, nickel- chromium-silicon, or HAI-NP1 . Page 6

Common Thermocouple TYPes - Types; Bn E, J, K, N, R, S, T, C (WsR) & P (Platinel ll)

The Type R thermocouple is composed of a platinum-13% rhodium (+) wire versus a platinum (-) wire. This type of thermocouple can be used in oxidizing or inert atmospheres with a service temperature range between 0 and 1480"C (321o 27OO"F). They should never be used in reducing atmospheres. As with all platinum type thermo- uples, they should always be protected with a ceramic protection tube. Alumina insulators and protection tubes preferred to prevent silica contamination from Mullite ceramics. When Type R thermocouples are continuously used at high temperatures, the elements can develop excessive grain growth in time causing mechanical breakage to the thermocouple. ln most situations platinum thermocouples should not be placed in any type of metal tube or in applications where metallic vapors are present. The Type S thermocouple is composed of a platinum-10% rhodium (+) wire versus a platinum (-) wire. This type of thermocouple can be used in oxidizing or inert atmospheres with a service temperature range between 0 and 1480'C (32 1o2700"F). They should never be used in reducing atmospheres. As with all platinum type thermo- couples, they should always be protected with a ceramic protection tube. Alumina insulators and protection tubes are preferred to prevent silica contamination from Mullite ceramics. When Type S thermocouples are continu- ously used at high temperatures, the elements can develop excessive grain growth in time causing mechanical break- age to the thermocouple. ln most situations platinum thermocouples should not be placed in any type of metal tube or The Type T thermocouple is composed of a copper (+) wire versus a nickel-45% copper (-) wire. The Type T thermocouple is frequently referred to as copper-constantan. This type of thermocouple can be used in oxidiz- ing, reducing, or inert atmospheres with a service temperature range between -200 and 370'C (-330 to 700'F). The high temperature use of this thermocouple is also limited due to rapid oxidation of the copper element. The Type T thermocouple is one of the few thermocouples which have established limits of error for use in subzero and cryo- genic applications. This is possible due to the Type T's superior corrosion resistance in moist environments. The Type C or WSR thermocouple is composed of a tungsten-S% rhenium (+) wire versus a tungsten-26"/" rhe- nium (-) wire. This Vpe of thermocouple can be used in high temperature vacuum or ineft atmospheres with a service temperature range up to 2316'C (4200'F). lt has very poor oxidation resistance, which must be taken into consideration. The Type C thermocouple is the most common tungsten-rhenium form of thermocouple due to the conductors being the least brittle at room temperature. This characteristic is very important since brittle con- ductors create inferior thermocouples. thermocouple is composed of a palladium-55%, platinum-31"/", and 14% gold (+) wire versus a65"/" gold and 35% palladium (-) wire. TheType Pthermocouple is a noble-metal form and should be protected in the same manner as a Type R, S, or B. This type of thermocouple was developed to approximate the ype K curve at high temperatures. lt can be used in oxidizing or inert atmospheres with a service temperature to 1260"C (2300"F). When using Type P thermocouples, Type K extension wire should be used. Tyrpe The Type P or Platinel 116 in applications where metallic vapors are present.

Note: The thermocouple types we describe in the Richards Catalog # 15 are the letter designations assigned by the lnstrument Society of America (lSA) and adopted as an American Standard in ANSI MC 96.1. The Type C and P letters are exceptions. The Type C and Type P are letter designations commonly used today by thermocouple manufacturers and not the lSA. There are a few other

more exotic types of thermocouples, which have been developed, but since they are rarely used we decided not to list them in this catalog. lf you have any questions regarding any of these other less common types of thermocouples, contact one of our sales engineers and we will be glad to assist you.

The Richards Screw Cover Head makes inspection of the thermocouple easy. Unscrew the cover withouf disconnecting the leads. The single element can now be pulled out for inspection. The element is installed into the connector without bending, which prevents the insulators from cracking. lf the element needs to be replaced, simply unscrew the two terminals and and install a new one. The cover will never get dropped or lost since the extension wires pass through the center. The cover and bushing are cast iron, which have been coated and then waxed to help prevent rust and corrosion.

Straight Thermocouple Assemblies - & N - Standard Weatherproof Aluminum Head

Metal Protection Tubes - Types E, Jn K

The Richards standard head (SH) style die cast aluminum weatherproof head is the most versatile head we offer. This head has a NEMA 4 rating for indoor or outdoor use in non-hazardous locations. The cover and body have been polished to help prevent corro- sion. The cover has a special silicone.gasket, which helps protects the connector block from wind-blown rain and dust. This gasket is also press fit into a groove to keep it irom falling out when the cover is removed for inspection. A stainless steel chain is attached to the cover and body to prevent it from getting misplaced. One of the most beneficial advantages to this type of head is the variety of connector blocks which can be used. The SH style head also can also be fitted with our in-head style (TS) transmitters'

Mullite has a maximum service temperature of 2900'F (1590'C). lt is considered to be better than Alumina for thermal shock resistance. Mullite tubes should be used with care, since they have poor mechanical shock resistance. Secondary metal tubes can be added for protection from mechanical damage. Mullite tubes are considered gas tight at high temperatures. All tubes which are used in horizontal installations and at elevated temperatures should be supported. Mullite tubes should not be used for primary protection tubes on noble metal (plati num based) thermocouples.

Silicon Carbide has a maximum service temperature of 2730" F (1500'C). lt has excellent resistance to thermal shock and the cutting action of flames. However, silicon carbide tubes are porous so they should not be used if a gas tight seal is required for protection of the thermocouple element. Because of their porousity, silicon carbide is usually used as secondary thermocouple protection tube. The SCI Vpe silicon carbide tubes are isopressed around a steel inner protection tube. This creates a gas tight unit, which is then considered a non- porous tube.

Straight Thermocouple Assemblies -

ffi,

on Tubes - Types E, J, K & N - With Screw Cover Head

The Richards Screw Cover Head makes inspection of the thermocouple easy. Unscrew the cover without disconnecting the leads. The single element can now be pulled out for inspection. The element is installed into the connector without bending, which prevents the insulators from cracking. lf the element needs to be replaced, simply unscrew the two terminals and and install a new one. The cover will never get dropped or lost since the extension wires pass through the center. The cover and bushing are cast iron, which have been coated and then waxed to help prevent rust and corrosion.

Mullite has a maximum service temperature of 2900'F (1590'C). lt is considered to be better than Alumina for thermal shock resistance. Mullite tubes should be used with care, since they have poor mechanical shock resistance. Secondary metal tubes can be added for protection from mechanical damage. Mullite tubes are considered gas tight at high temperatures. All tubes which are used in horizontal installations and at elevated temperatures should be supported. Mullite tubes should not be used for primary protection tubes on noble metal (platinum based) thermocouples,

Silicon Carbide has a maximum service temperature of 2730" F (1500"C). lt has excellent resistance to thermal shock and the cutting action of flames. Howevet silicon carbide tubes are porous so they should not be used if a gas tight seal is required for protection of the thermocouple element. Because of their porousity, silicon carbide is usually used as secondary thermocouple protection tube. The SCI type silicon carbide tubes are isopressed around a steel inner protection tube. This creates a gas tight unit, which is then considered a non-porous tube.

Straight Thermocouple Assemblies - \ K & N - Standard Weatherproof Aluminum Head

Ceramic Protection Tubes - Types E, J,

The Richards standard head (SH) style die cast aluminum weatherproof head is the most versatile head we offer. This head has a NEMA 4 rating for indoor or outdoor use in non-hazardous locations. The cover and body have been polished to help prevent corro- sion. The cover has a special silicone gasket, which helps protects the connector block from wind-blown rain and dust. This gasket is also press fit into a groove to keep it from falling out when the cover is removed for inspection. A stainless steel chain is attached to the cover and body to prevent it from getting misplaced. One of the most beneficial advantages to this type of head is the variety of connector blocks which can be used. The SH style head also can also be fitted with our in-head style (TS) transmitters.
