XIQI Electric CG-WRNT-03 K-Type Thermocouple Sensor - M8 Thread, 5x100mm Probe, 1m Cable

The CG-WRNT-03 is a K-type thermocouple, which outputs a low-level millivolt (mV) signal proportional to the temperature difference between its probe tip and the cold junction (reference point). This raw analog signal requires connection to a thermocouple input module, temperature transmitter, or controller with built-in cold-junction compensation for accurate temperature readout.

Drill and tap an M8 mounting hole at the desired measurement point. Insert the probe and hand-tighten the M8 nut until the compression spring is fully compressed, ensuring the probe tip is flush and under consistent pressure against the target surface. This spring-loaded design compensates for thermal expansion and surface irregularities for stable contact.

The sensor probe is rated for continuous operation from 0°C up to 600°C, as defined by its K-type thermocouple alloy and stainless steel sheath. Ensure the attached cable is routed away from direct heat sources exceeding its insulation rating to prevent damage. For short-term peaks, consult the manufacturer's specifications.

Yes, but it must be done correctly to maintain accuracy. Use thermocouple extension wire of the same type (K-Type) and correct polarity. All connections must be secure and kept at a stable, similar temperature to avoid introducing measurement errors from additional thermocouple junctions. For long runs, consider using a temperature transmitter with a 4-20mA or digital output near the sensor.
