Brief Introduction:
The Bimetal Thermometer is a versatile field detector instrument designed for the precise measurement
of temperatures within the middle and low range. This instrument proficiently measures the
temperature of liquid, steam, and gas, spanning a broad range from -50ºC to +500ºC across diverse production processes.
Key Features:
1. On-site display for temperature readings, ensuring an intuitive and user-friendly experience.
2. Offers exceptional safety and reliability with an extended lifespan.
3. Available in multiple structural forms to cater to various requirements.
Working Principle:
The Bimetal Thermometers are constructed with a bimetallic strip coiled into a circular shape. When one end is heated, the strip expands and actuates the pointer to rotate, thereby displaying the corresponding temperature value on the instrument.
