Thermocouples - Probes with Bayonet Fittings

! Note: If you would like to order a Type E, J, N, or Type T assembly, just substitute the “ K “ with a “ E “, “ J “, “ N “, or “ T ” in the part numbers listed on this page. Double element assemblies are also available. Add a ” D ” to the part number. Example: 20KBDG9M3-X-Y-U Probes can also be made with Types: B, R, and S, phone for details. Also, sheaths can be made of other materials and sizes - see page on “Miniature Tubes”. “ U ” = Bayonet Fitting Location, “ X ” = overall length, “ Y ” = probe length, “ Z ” = Flexible Extension Length, “ C ” = Cold Leg length, and “ H ” = Hot leg length.

Thermocouple Probes have a maximum service temperature of 1300°F(700°C) depending on the type and gauge of the thermocouple wire used in their construction. The Bayonet Fitting presets the depth and allows quick attachment and removal. The elements are made with impregnated fiberglass wire. The 30 gauge 1/16” O.D. probes have a high temperature limit of 400°F (200°C) due to Kapton insulation on the element. A grounded junction is standard to help prevent the element from pulling out of the tube and to provide a rapid temperature response time.

Application

Probe, Bayonet Fitting Standard plain Bayonet Fitting probe. Specify : “ X ” overall length, and “ Y ” probe sheath length. Specify “ U ” Length for location of Bayonet Fitting on probe. If it is at the tip of the hot end then “ U ” = 2 (2 inches).

Probe, Bayonet Fitting Overbraided OB8 = 304SS OB9 = Alloy 9 (600)

The overbraid is on the exposed insulated wire portion of the probe - from the sheath to the cold end. It is used to protect the insulation from abrasion and to help shield against electrical pick up.

4 Probe, Bayonet Fitting & Flexible Extension Flexible extensions ( FE ) are made with Armored Cable ( AC ). The ” Z ” dimension may or may not completely cover the normally exposed insulated wire depending on what length you specify for the “ Z ” length. Probe, Angle, Bayonet Fitting 90 degree and 45 degree angel are standard, but other angels can be or- dered. The part numbers shown are for 45 degree probes. For 90 degree, change the “45” to “90” in the part number. For the optional Relief Spring ( SR ) add “ SR ” to the end of the part number . Probe, Angle, Bayonet Fitting, Flexible Extension 90 degree and 45 degree angel are standard, but other angels can be or- dered. The part numbers shown are for 90 degree probes. For 45 degree, change the “90” to “45” in the part number. The Compression Fitting is optional, if desired add “ CF ” to the part number. Spade Lugs ( LS ) also avail- able (at added cost). 5 6
