WSSX-411 Industrial explosion-proof electric contact bimetallic thermometerDetailed product description：

detailed introduction

1. Application
Electric contact bimetallic thermometers are used in production sites for automatic temperature control and alarm. It can directly measure the temperature of liquid, steam, and gas media within the range of -80 ℃ to+500 ℃ in various production processes. Industrial thermometer series

2. Characteristics
On site temperature display, intuitive and convenient;
Equipped with automatic power-off and alarm functions;
Safe and reliable, with a long service life;
Multiple structural forms to meet different requirements

3. Working principle
Electric contact bimetallic thermometer uses temperature changes to drive contact changes. When it contacts or disconnects with the upper and lower limit contacts, the relay in the circuit is activated, thereby automatically controlling and alarming.
