WZPK-404S Bimetallic Thermometer with Electrical Contact
The WZPK-404S bimetallic thermometer with electrical contact is an industrial process control instrument designed for temperature monitoring and automated regulation. Utilizing the thermal expansion principle of bonded bimetal strips, this device accurately converts temperature variations into mechanical displacement while providing configurable electrical switching functions for control applications.
Featuring a rugged construction, the instrument integrates a hermetically sealed gauge head with anti-fogging glass lens and luminescent dial markings. The corrosion-resistant sensing assembly incorporates vibration-damping technology to maintain measurement consistency. Electrical contacts employ precious metal alloys to ensure stable switching performance. Available in 304 stainless steel or aluminum enclosures, the device offers IP65 protection and operates within -20℃ to 500℃ range.
Key Features:
- Helical bimetal sensing element ensures responsive and reliable temperature detection
- 360-degree rotatable gauge head facilitates optimal viewing angle adjustment
- Configurable contact arrangements including SPDT and DPDT options
- Hermetic sealing prevents media ingress in steam, oil, or chemical environments
- Dry contact output compatible with diverse control systems
Typical Applications:
Widely implemented in food processing lines, pharmaceutical reactors, chemical pipeline monitoring, and HVAC systems requiring local indication with remote control integration. Common use cases include temperature safeguarding for fermentation tanks, overtemperature alarms in heat exchangers, and interlock controls for boiler auxiliaries.
