【Product Description in English】
The WRR2-130 Bimetallic Thermometer with Electrical Contact is an industrial-grade integrated instrument for temperature measurement and control, designed based on the bimetal sensing principle. Widely used in process industries, mechanical equipment, and environmental monitoring systems, this device utilizes the deformation characteristics of bimetal strips under temperature variations to drive the pointer for real-time temperature indication. Its adjustable electrical contact mechanism generates switching signals when preset temperature thresholds are reached, enabling precise monitoring and automated system coordination.
Featuring a fully enclosed stainless steel housing with polished and anti-corrosion treatment, the device maintains reliable performance in challenging environments including high temperature, humidity, and dusty conditions. The high-contrast dial with wear-resistant glass window ensures clear visibility, while precision-calibrated pointer and scale mechanisms deliver consistent measurement accuracy across common industrial temperature ranges. The electrical contact system employs silver alloy contacts compatible with standard control circuits, offering configurable single upper/lower limit or dual contact settings for flexible application requirements.
Engineered for installation flexibility and maintenance efficiency, the thermometer supports axial, radial, and adjustable mounting orientations, compatible with DN20 to DN100 industrial pipe connections. Modular internal components simplify maintenance procedures and reduce lifecycle costs. Integrated overload protection safeguards control systems from abnormal current conditions.
Ideal for temperature monitoring and interlock control in thermal pipelines, chemical reactors, HVAC systems, and food processing equipment, this instrument enhances automation capabilities and energy management efficiency while maintaining measurement precision. Its robust construction and adaptive design make it a practical solution for modern industrial temperature regulation needs.
