WRQ-131 Bimetallic Thermometer with Electrical Contact
The WRQ-131 bimetallic thermometer with electrical contact is an industrial-grade temperature measurement and control instrument utilizing thermal bimetal sensing technology. This device converts temperature variations into mechanical displacement through its helical bimetal sensing element, featuring adjustable contact system for reliable signal transmission in diverse industrial environments.
Constructed with multi-layer bonded bimetal strip, the thermometer demonstrates exceptional thermal responsiveness and mechanical durability. The fully enclosed housing integrates dustproof/water-resistant casing and corrosion-resistant stainless steel protection tube, ensuring stable operation under challenging conditions including vibration and particulate exposure. The high-contrast dial with luminous indicators guarantees clear readability in low-light environments.
Available in single or double contact configurations, the product employs silver alloy contacts capable of handling up to 250V AC and 1A current load. User-adjustable set points are easily configured via external dial knobs. When measured temperature reaches preset values, the contact mechanism activates switching signals for equipment interlocking or alarm functions. Measurement ranges span from -80℃ to +500℃, with customizable scale segments to suit operational requirements.
Featuring modular construction, the thermometer allows quick disassembly for maintenance and component replacement. The wide-angle lens accommodates multi-directional observation, while optional axial or radial installation types adapt to various pipeline and equipment configurations. This instrument serves as a dependable temperature monitoring solution for petrochemical plants, thermal distribution networks, food processing systems, and general industrial automation applications.
