Product Description
EP Extension Grade Thermocouple Wire
Thermocouple Extension Wire
Type E Thermocouple extension wire (EP--Ni-Cr, EN-Cu-Ni) offers stronger signal and higher accuracy than Type K or Type J at moderate temperature ranges up to 1,000°F. Its enhanced stability compared to Type K contributes to superior measurement precision.
Our manufacturing facility specializes in producing various thermocouple compensating wires including KX, NX, EX, JX, NC, TX, SC/RC, KCA, and KCB types for temperature measurement instruments and cables. All products comply with:
- GB/T 4990-2010 'Alloy wires of extension and compensating cables for thermocouples' (Chinese National Standard)
- IEC584-3 'Thermocouple part 3-compensating wire' (International standard)
These instrumentation cables feature construction similar to pair instrumentation cable but with specialized conductor materials designed for process temperature measurement. They maintain thermo-electric (emf) properties matching the connected thermocouples.
