Bimetallic Temperature Switch WRP-130 Product Introduction
Product Overview
The WRP-130 bimetallic temperature switch combines temperature measurement and electrical switching functions in a rugged mechanical design. Utilizing a helical bimetallic strip sensing element, this industrial-grade instrument provides local temperature indication and adjustable setpoint control without requiring external power supply. Its hermetically sealed construction ensures reliable performance in harsh environments.
Technical Features
◆ Helical Bimetallic Sensor: Precisely calibrated spiral-wound strip converts thermal expansion into rotational movement, covering -50℃ to 500℃ ranges (customizable)
◆ Dual Adjustable Contacts: Two independent magnetically assisted switching points with maximum rating AC 220V/1A (DC 30V/1A), switching differential ≤±1.5% of span
◆ Robust Housing: Die-cast aluminum or stainless steel enclosure with IP65 protection, available in 100mm dial size with axial/radial/universal mounting options
◆ User-friendly Interface: High-visibility white dial with black graduations, luminescent orange pointer, and field-adjustable setting knobs
Operational Benefits
▼ Intrinsically safe operation in EMI environments
