电接点双金属温度计WRP2-131产品介绍（英文版）

The WRP2-131 Bimetallic Temperature Gauge with Electrical Contact is a mechanical temperature measurement and control device specifically designed for industrial applications. Utilizing the bimetallic sensing principle, this instrument integrates adjustable electrical contacts to achieve temperature monitoring and signal output functions, making it suitable for process temperature management in various industrial environments.

The product features an integrated structure comprising a thermal sensing element, indicating mechanism, electrical contact system, and protective housing. Constructed with 304 stainless steel casing, the device demonstrates excellent mechanical strength and corrosion resistance, capable of operating within a temperature range of -20℃ to +500℃. The white dial with black graduations and red indicator pointer ensures clear visibility under diverse lighting conditions.

The technical core of this instrument lies in the precise coordination between the bimetallic helical sensing element and the mechanical transmission system. Temperature variations drive the pointer to accurately display current temperature readings. The magnetic-assisted contact system incorporates dual adjustable setting pointers for independent temperature control point adjustment via dedicated knobs. When the measured temperature reaches preset values, the contact mechanism activates external circuits to trigger alarms or control actions.

This device finds application in temperature monitoring systems across petroleum refining, chemical processing, machinery manufacturing, and food production industries. It is compatible with heat exchangers, storage tanks, and pipeline systems. Three installation configurations (axial, radial, and adjustable angle types) are available to accommodate different piping layouts. The IP65 protection rating effectively prevents dust ingress and water spray interference.

Regular maintenance should include inspection of pointer movement smoothness and dial cleanliness to ensure measurement accuracy. Electrical load parameters must comply with specified capacity ratings, with recommendation for signal amplification through intermediate relays. Installation should avoid environments with excessive vibration, and operating temperatures must not exceed calibrated ranges. Professional technicians are advised to perform internal maintenance to preserve mechanical integrity.
