XIQI Electric CG-WRNT-01 K-Type Compression Spring Thermocouple Sensor - M12 Thread, 1m Cable

This is a passive K-type thermocouple sensor. It outputs a small millivolt (mV) signal that varies with temperature. This signal must be connected to a dedicated thermocouple input on a temperature controller, PLC, or data logger equipped with cold-junction compensation and appropriate signal conditioning to provide an accurate temperature reading.

Yes, but it must be done correctly to maintain accuracy. You must use extension wire specifically rated for K-type thermocouples, which matches the thermoelectric properties of the sensor wire. Using standard copper wire will introduce significant measurement errors. Ensure all connections are clean, tight, and kept at a stable, similar temperature.

The compression spring design is primarily optimized for surface temperature measurement, as it ensures good mechanical and thermal contact. For air or gas temperature sensing, a different probe style (like an exposed junction or sheathed probe in a thermowell) is typically more appropriate. However, it can be used in high-velocity air streams if mounted properly.
