Product Overview
The WRNR-01 Bimetal Thermometer with Electrical Contact is a precision instrument designed for industrial temperature monitoring and control, widely used in petrochemical, power generation, food processing, and pharmaceutical industries. It utilizes bimetal strip sensing technology to drive pointer movement via differential thermal expansion, providing clear temperature indication. The electrical contact feature enables联动 with control systems to trigger alarms or automatic adjustments when temperature limits are exceeded, ensuring operational safety and process stability. Its measurement range spans from -80°C to +500°C, suitable for liquids, steam, and gases.14
Key Features
The WRNR-01 incorporates anti-vibration design with options for silicon oil filling or separated structure to minimize environmental interference. The stainless steel casing enhances corrosion resistance for harsh conditions. Multiple installation options (axial, radial, universal) and connection types (movable external thread, fixed flange) ensure adaptability. The electrical contact supports adjustable upper/lower limits or dual-limit configurations, featuring reliable relay compatibility and user-friendly operation. With a rapid thermal response time of ≤40 seconds, it guarantees real-time accuracy.51217
