Product Description of WSSX-480 Electromechanical Bimetal Thermometer with Contact
The WSSX-480 bimetal thermometer with electrical contact is a mechanical instrument designed for industrial temperature monitoring, combining bimetal sensing technology with contact control system. This dual-function device performs temperature indication and contact control through mechanical operation, suitable for thermal system monitoring in petrochemical plants, food processing facilities, HVAC systems and other industrial applications.
Constructed with 304 stainless steel enclosure, the device features a 100mm dial diameter and adjustable mounting flange. Measuring range spans from -40℃ to +500℃ with customizable scale options. The two-tone dial with black pointer and red warning markers ensures clear visibility under various lighting conditions.
The core bimetal sensing element undergoes specialized heat treatment to ensure precise mechanical transmission through differential thermal expansion. Silver alloy contacts provide reliable electrical switching capability rated at AC220V/3A. With IP55 protection rating, the device resists dust ingress and water splashes effectively. Standard radial stem accepts 100mm to 400mm immersion length, supporting G1/2" threaded or flange mounting.
Key advantages include self-powered operation requiring no external energy source for temperature indication and contact activation. Built-in vibration dampener enhances operational stability in dynamic environments. The dual-setpoint adjustment mechanism allows independent setting of high/low alarm thresholds via dial-mounted knobs. Compatible with steam, thermal oil, water and other industrial fluids, with optional corrosion-resistant material versions available.
This mechanical design ensures long-term reliability in harsh operating conditions while maintaining straightforward installation and maintenance procedures. The product delivers practical temperature monitoring solution for equipment protection and process control applications across multiple industries.
