Compensating cables are used for the transmission of thermoelectric voltage from thermocouple to cold junction , the so called "black box". Due to the different applications as for example in smelteries, cold stores or in liquid gas systems where always a reliable and safe transmission of the occuring thermoelectric voltage in mV must be ensured, the compensating and extension cables manufactured by us are insulated with different materials respectiveley the thermoelectric voltage and cable are protected by braidings, foils and /or armouring.
