Product Overview
The WZPK-134S bimetallic temperature switch with electrical contact is a mechanical instrument designed for industrial temperature monitoring and control. Utilizing bimetallic helix sensing technology, it triggers preset contacts through mechanical displacement caused by temperature variation, enabling real-time temperature feedback and equipment interlocking. Suitable for diverse industrial applications requiring temperature safety supervision, process regulation, and automated system integration, this device delivers stable temperature management without relying on external power sources.

Key Features

1. Bimetallic Sensing Technology
   Equipped with a high-sensitivity bimetallic helix element that generates linear deformation in response to temperature changes. The mechanical transmission system directly drives the pointer and contact mechanism, ensuring short signal paths and rapid response. Specially treated sensing components enhance stability and minimize vibration interference.

2. Contact Control Module
   Adjustable contact configuration supports single upper/lower limit or dual limit settings. Contact capacity meets standard control requirements for driving small relays or signaling devices. Silver alloy contacts deliver superior conductivity and wear resistance, maintaining stable contact resistance during frequent operations.

3. Protective Construction
   Full-sealed stainless steel housing (IP65 rated) with temperature-resistant silicone oil filling prevents moisture ingress and media crystallization. Reinforced glass lens with pressure-balancing seal ring provides explosion-proof performance, suitable for pipeline installations with minor pressure fluctuations.

4. Multi-scenario Adaptability
   Available in axial/radial mounting orientations with 100mm dial diameter. Standard ranges cover -50~500℃. Customizable process connections include M27×2 threaded, flanged, or industrial standard fittings, compatible with DN15-DN200 pipelines.

Application Scenarios
• Petrochemical plants: Reactor temperature monitoring, pipeline freeze protection
• HVAC systems: Heat exchanger overheat protection, boiler water interlock
• Food processing: Sterilization equipment temperature control, fermentation tank regulation
• Mechanical systems: Hydraulic oil temperature monitoring, bearing overheat warning
