Bimetallic Thermometer with Electrical Contact WZPK-135U Product Introduction

Product Overview:
The WZPK-135U bimetallic thermometer with electrical contact combines composite sensing technology with mechanical transmission structure, delivering both temperature measurement and contact control functions. Utilizing the thermal deformation effect of bimetallic strips to drive the pointer for temperature indication, this device features adjustable contact mechanisms that automatically trigger switch signals when reaching preset temperature thresholds, making it suitable for industrial temperature monitoring and process control applications.

Key Features:

1. Dual-Function Integration
   Integrates temperature display with contact control capabilities, providing precise temperature indication while enabling equipment interlock protection or alarm functions, effectively reducing field instrument configurations.

2. Enhanced Mechanical Design
   Constructed with fully sealed stainless steel casing and vibration-resistant bearing system, achieving IP65 protection level. The optimized pointer mechanism ensures measurement accuracy within ±1.5%FS across the -40℃ to 500℃ range under various environmental conditions.

3. Flexible Configuration
   Equipped with rotatable head and multi-directional installation interfaces, supporting axial/radial/universal mounting orientations. Contact settings can be easily adjusted via dedicated knobs with action differential controlled within 2% of span.

4. Reliable Control Interface
   Incorporates dual independent electrical contact modules with silver alloy contacts, capable of handling 220V AC/3A loads. Synchronized contact action and dial indication provide real-time operational feedback for field personnel.

Application Scenarios:
Ideal for temperature monitoring and equipment interlock requirements in petroleum processing units, thermal pipeline networks, food processing equipment, pharmaceutical production lines, and other industrial environments with frequent vibration or complex operating conditions.

Maintenance Guidance:
Regularly inspect casing seal integrity and perform zero-point calibration every 12 months. Use anhydrous ethanol for contact surface cleaning during maintenance, avoiding corrosive cleaning agents.
