Thermocouple Compensating Cables

A Thermocouple Cable is usually a pair of insulated conductors made from two different metals with the same or similar properties to the thermocouple probe. They carry the signal from the probe back to the measuring unit. To transmit the signal there must be a positive (+) and negative (-) conductor. These conductors are often referred to as legs. Two legs make a pair and you must have a pair for a thermocouple to operate. Multiple Pair Cables are also used where a number of sensors or probes in one area link back to a control panel.
