Introduction to the SUP-WZPK Temperature Sensor
The SUP-WZPK temperature sensor is an RTD temperature sensor designed for measuring temperature in liquid and gas media with high stability and reliability. Utilizing Pt100 or Pt1000 sensing elements and a robust protective probe structure, the sensor is well-suited for temperature monitoring in a wide range of industrial systems. Its threaded installation design enables convenient mounting while ensuring a secure and leak-free connection at the installation point.
The SUP-WZPK is widely used in HVAC systems, refrigeration equipment, process pipelines, storage tanks, and various manufacturing processes. The product is available with multiple probe sizes, insertion lengths, and output signal options, allowing it to meet diverse installation and application requirements across industrial environments.

Operating Principle of the Sensor
The SUP-WZPK temperature sensor utilizes a Pt100 or Pt1000 sensing element to measure temperature. As the ambient temperature changes, the electrical resistance of the platinum element inside the sensor varies accordingly. A controller or signal transmitter detects this resistance change and converts it into an actual temperature value.
Based on the resistance temperature detection (RTD) principle, the SUP-WZPK provides high measurement accuracy and long-term operational stability. The sensor is typically installed directly on pipelines, storage tanks, or industrial equipment to monitor the temperature of liquids and gases throughout the production or operating process.
