Hazardous location certified Heat-Tracing Thermocouple assemblies are designed for use in systems that measure the surface temperature of process pipe that is carrying products whose temperatures must be controlled to prevent freeze-up, or to maintain a viscosity level so that the inner medium will flow. These products are CSA Certified for use in US and Canada hazardous locations designated: Class I, Division 2, Group A,B,C,D; Class II, Division 2, Group F,G; Class III; and USA: Class I, Zone 2, Group IIC; Zone 22, Group IIIB; Zone 22, Group IIIC; T6…T1: with non-incendive field wiring, Ingress Protection: IP66, Type 4X. The service temperature range for Certified Assemblies is limited to -25 ºC to 435 ºC and the T-code corresponds to the higher of ambient or process temperature. These Thermocouples are offered in a variety of temperature ranges and are supplied with a 316SS sheath, and a 3/4" radius stainless steel mounting pad.
