Straight Thermocouple Assembli,es " Double Tube - Types E, J, K A ru+

The Richards Double Tube Thermocouple Assemblies are designed for severe service applications. The double tube assem- blies with a metal outer tube are for applications where mechanical damage and thermal shock to the thermocouple is a problem. The double tube assemblies, which have a Silicon Carbide outer tube, are for applications where thermal shock and flame contact is a problem. Double ceramic tube assemblies are for extra protection against corrosive atmospheres. We offer many other comblnations of double tubes, which we could not list in this catalog due to space limitations. Richards double tube assemblies can be made from any type of metal or ceramic tube, which is available. I No/re: If you would like to order a Type E, J, or Type N assembly, just substitute the K with a E, J, or N in the part numbers listed on this page. Triple tube assemblies are also available.
