Product Overview
The WRQ-130 Bimetallic Thermometer with Electrical Contact is a precision instrument designed for industrial temperature monitoring and control, suitable for measuring liquids, steam, and gases. Its core sensing element consists of a bimetallic strip that mechanically deforms with temperature changes, driving a pointer to indicate values while activating electrical contacts for automated control or alarms. With a measurement range of -80°C to +500°C, it adapts to diverse industrial requirements. The robust housing, crafted from corrosion-resistant materials, ensures durability in harsh environments. The design combines clarity with versatility, offering axial, radial, or adjustable mounting options for flexible installation.11226
Key Features
The WRQ-130 delivers high accuracy (±1.5% of span) and rapid response (≤40s). Its electrical contacts, made of wear-resistant materials, allow adjustable upper/lower limits to trigger relays for circuit control. Available in multiple dial sizes (60/100/150mm) and installation configurations (threaded, flanged, or sleeve-mounted), it caters to varied operational needs. The IP55-rated enclosure provides dust and water splash resistance, enhancing longevity. The intuitive display and reliable switching mechanism make it ideal for automated systems.51620
Applications
This thermometer is widely used in petrochemicals, power generation, food/pharmaceutical production, and environmental monitoring. In refineries, it tracks reactor and pipeline temperatures; in power plants, it safeguards boiler operations; in food processing, it ensures compliance with thermal safety standards. Its vibration-resistant and anti-corrosion design also suits marine and heavy machinery applications. By integrating real-time readings with alarm functions, the WRQ-130 significantly boosts operational safety and productivity.2622
