EXTENSION / COMPENSATING CABLES

 

Extension and compensating cables are available in single and multi cores fibre glass, PVC, asbestos &teflon insulations in different combination.

Compensating cables having e.m.i. characteristics identical to their basic thermocouples in a restricted temperature span as per ANSI std. are available. Shielding in the form of AluminiumMylar tape can be provided.
