Electrical Contact Bimetal Thermometer WZPK-476U Product Introduction (English)
The WZPK-476U Electrical Contact Bimetal Thermometer is an industrial instrument integrating temperature measurement and control functions, designed for temperature monitoring and automated management in diverse complex working conditions. Utilizing bimetal strip sensing technology, the thermometer operates based on the deformation principle of two bonded metals with different thermal expansion coefficients. This mechanism drives the pointer to indicate temperature values, while preset electrical contacts enable temperature signal output and control functions.
The WZPK-476U emphasizes practicality and reliability. Its core components are constructed from corrosion-resistant alloy materials, offering excellent resistance to vibration and shock, ensuring stable performance in high-temperature, humid, or mildly corrosive environments. The sealed housing design effectively blocks dust, moisture, and other external contaminants, protecting internal mechanisms and extending service life. The electrical contact module employs a high-sensitivity switching mechanism, allowing users to set upper and lower temperature limits. When the measured temperature reaches preset thresholds, the contacts trigger switch signals to activate external devices for temperature regulation or safety protocols, making it ideal for automated control systems.
With a broad temperature measurement range spanning from -80℃ to +500℃, this thermometer meets the needs of most industrial applications. The clear dial markings, customizable dial sizes, and precision levels ensure quick and accurate readings. Flexible installation options include radial, axial, or adjustable orientations to accommodate various equipment interfaces. Additionally, the product requires minimal maintenance, retaining long-term measurement stability without complex recalibration procedures.
The WZPK-476U is widely used in petroleum refining, power generation, food processing, pharmaceuticals, HVAC systems, and other industries. It is suitable for temperature monitoring and control in reactors, pipelines, storage tanks, and similar equipment. By combining precise measurement with automated control capabilities, this thermometer provides an efficient temperature management solution, enhancing operational safety and energy efficiency in industrial processes.
