Thermocouple Extension & Compensating Cables

Thermocouple Extension & Compensating CablesThermocouple extension and compensating cable have guaranteed identical
characteristics to their basic thermocouples in the restricted
temperature span.Each batch of cable is tested for thermo emf performance and electrical
and mechanical properties as per international standard.We follow ANSI MC 96.1 standard for thermo-emf performance test for Thermocouple cables. Table 1- Maximum InductanceCable Type
