Bimetallic Thermometer with Electrical Contact WZPK2-405SA Product Introduction
Product Overview
The WZPK2-405SA bimetallic thermometer with electrical contact is an industrial-grade temperature measurement and control instrument based on the bimetallic thermal element principle. Manufactured with high-quality metal materials, the device utilizes mechanical deformation caused by temperature changes to drive the pointer for temperature indication, while incorporating an adjustable electrical contact mechanism for temperature signal output. This dual-function instrument combines local visual display with electrical signal transmission, making it suitable for various industrial applications requiring temperature monitoring and automated control.
Key Features
The thermometer employs an optimized spiral bimetallic strip structure, maintaining stable temperature response characteristics across a broad measurement range from -20℃ to 500℃. The 304 stainless steel housing with sealed construction ensures long-term reliability in challenging environments containing dust or moisture. The dial features high-contrast graduations and anti-fog treatment for clear visibility under harsh conditions. The electrical contact system includes two adjustable contact points, allowing flexible configuration of upper/lower alarm limits according to process requirements. Multiple installation configurations (axial/radial) are available to accommodate different equipment layouts.
Application Scenarios
This instrument is widely used in temperature monitoring for petrochemical installations, process control in food/pharmaceutical production lines, energy management of HVAC systems, and operational status monitoring of mechanical equipment. Its robust design meets the long-term service requirements in power generation, metallurgy, water treatment and other industrial sectors, particularly suitable for automated systems requiring integration of local observation and remote control capabilities.
