Product Overview
The WZP-270U bimetal thermometer with electrical contact is an industrial-grade temperature measurement instrument designed based on bimetal sensing principle. It provides direct measurement for liquids, steam and gases within -80℃ to +500℃ range. The product features local temperature display with clear reading, combined with automatic control and alarm functions through contact switching mechanism. The stainless steel protection tube ensures corrosion resistance and pressure withstand capability, making it suitable for petrochemical, power generation and metallurgical applications. Multiple dial sizes and flexible installation options are available to meet different operational requirements.18
Key Features
The WZP-270U utilizes precision-engineered bimetal helix element that drives both indicating pointer and control contacts with temperature variation. Its weatherproof enclosure and specially treated internal components effectively minimize vibration interference. The thermometer offers axial, radial or adjustable angle mounting styles with optional threaded or flange fixing methods for versatile field installation. The clearly graduated dial shows smooth pointer movement while the reliable contacts ensure long service life. Customizable protection tube lengths and material options including 1Cr18Ni9Ti stainless steel accommodate various medium conditions.1214
Applications
This electrical contact bimetal thermometer finds wide applications in reactor temperature monitoring for petrochemical plants, steam pipeline measurement in power systems, machinery thermal protection and process control for food & pharmaceutical production. It is particularly suitable for scenarios requiring both local indication and remote control such as boiler temperature supervision, HVAC systems and industrial ovens. The safety-oriented design makes it competent for explosive atmosphere. Its compact structure and stable performance have made it an ideal choice for industrial temperature measurement.317
Technical Specifications
The WZP-270U delivers 1.5-class accuracy with thermal response time ≤40 seconds. Operating environment ranges from -25℃ to +55℃ at ≤85% relative humidity. Contact rating reaches 10VA (resistive load) with 0.7A maximum current. Available dial diameters include 100mm and 150mm versions while protection tubes come in φ6, φ10 or φ12mm diameters depending on length. Standard mounting threads include M27×2 and G1/2 with pressure resistance up to 6.4MPa. The switching differential stays within 1.5 times of basic error limit while repeatability error remains below half of basic error limit value.2326
