D&N Stocks a wide range of Thermocouple Cable insulation to suit most applications. D&N sells cable online in lengths of 5 meters. If you require custom lengths please contact our sales team.
When constructing a Thermocouple circuit it’s wise to construct the length component of the circuit with a compensating or extension cable. Generally constructed by using an M.I. Thermocouple cable which is in direct contact with the heat source and extends to a point where compensating or extension cable can be used at a lower temperature.
Care must be taken from this point to maintain the same emf of the hot end junction to that of the extension cable used, it is best to use the same material as the Thermocouple cable used in the hot end. It is all so recommended that all junctions contain the same emf as the conductor, The Thermocouple plug and jacks supplied by D&N Engineering conform to the compensation nature of the Thermocouple cable used.
When choosing the temperature cable care must be taken into consideration, when choosing compensating grade cable and extension grade cable. Compensating cable can be used as the hot end junction at the point of measurement and be used as and extension over a long run. Thermocouple Extension cable prefix (EX) can only be used as and extension to attach to a Thermocouple compensating junction.
There are many types of insulation used in extension or compensating cable all with varying degrees of thermal resistance and tensile strength. When selecting an extension cable a few factors must be taken into account.
