Type K Thermocouple Extension Wire 2*7/0.25 for Process Temperature Measurement with 32 to 392F Range and +/- 2.2C EMF Tolerance
Type K extension cable KXBBP 2*7/0.25 green is a customized thermocouple extension wire. These compensation cables, also known as instrumentation cables, are specifically designed for process temperature measurement applications.
Thermocouple extension cables connect thermocouples to pyrometers for temperature indication and control. The conductors in these cables have thermo-electric (emf) properties matching those of the thermocouples they connect to.
Our manufacturing facility specializes in producing various types of thermocouple compensating wires including:
- KX, NX, EX, JX
- NC, TX, SC/RC
- KCA, KCB
All our thermocouple compensating products comply with:
- GB/T 4990-2010 (Chinese National Standard)
- IEC584-3 (International standard)
