What is compensating cable (CA)?

Compensating cable

• cable type is indicated with the letters CA (Compensating Alloy), e.g. for K type thermocouple the cable type is KCA.
• wires have similar electrical features as the sensor's thermo wires, but they are not exactly same materials
• this solution is more cost effective than extension wires, but the maximum temperature allowed is lower, depending on insulation materials in range of 100…200 °C.
