XIQI Electric CG-WZPT-03 PT100 Thermocouple Sensor, M8 Thread, 5x50mm Probe, 2m Cable, 0-800°C

The CG-WZPT-03 is a PT100 Resistance Temperature Detector (RTD), not a thermocouple. It uses a platinum element whose resistance changes predictably with temperature, offering good accuracy and stability over the 0-800°C range. It provides a resistance output (typically 100Ω at 0°C) that requires an RTD transmitter or compatible PLC input for signal conditioning.

This 2-wire PT100 sensor outputs a resistance. You must connect it to a dedicated RTD input module on a PLC, a temperature transmitter, or a data logger with PT100 support. Do not connect it directly to a power supply. The transmitter will convert the resistance into a standard industrial signal like 4-20mA or a digital communication protocol for easy integration.

The sensor features a standard M8 metric thread on the probe for direct installation into a tapped hole on your equipment or a thermal well. Ensure the thread is sealed properly, typically with a copper crush washer or high-temperature thread sealant, to prevent leaks in pressurized systems and ensure good thermal contact.

Yes, the stainless steel construction and threaded M8 mounting provide a robust, mechanically secure installation suitable for environments with moderate vibration, such as industrial machinery. For extreme vibration, additional support for the cable near the connection point is recommended to prevent fatigue failure.
