XIQI Electric CG-WRNT-03 K-Type Thermocouple Sensor - M8 Thread, 5x50mm Stainless Steel Probe, 1m Cable

This sensor has an integrated 1-meter cable with bare wire leads at the end. The leads correspond to the positive and negative conductors of the K-type thermocouple and are designed for direct connection to screw terminals on a temperature controller, PLC, or data logger with thermocouple input capability.

This CG-WRNT-03 model features a grounded junction, where the thermocouple wires are physically welded to the inside of the stainless steel probe sheath. This provides faster thermal response time but creates an electrical connection to the sheath, which can be susceptible to electrical noise in some environments compared to an isolated (ungrounded) junction.

Yes, but not directly. This sensor outputs a small millivolt signal specific to K-type thermocouples. You will need a dedicated thermocouple amplifier and cold-junction compensation (CJC) module, such as a MAX6675 or MAX31855 breakout board, to accurately read the signal and convert it to a digital value compatible with microcontroller ADCs.

The specified operating temperature range is 0°C to 600°C. The stainless steel sheath and mineral insulation are rated for continuous use within this range. Exceeding 600°C may degrade accuracy, damage the insulation, or shorten the sensor's lifespan. For higher temperatures, a sensor with an Inconel sheath would be required.
