1. Product Introduction
Bimetallic thermometer is a field detection instrument suitable for measuring medium and low temperatures. It can directly measure the temperature of liquid, steam and gas medium in the range of -80℃～+500℃ in various production processes. The thermometer has the characteristics of waterproof, corrosion-resistant, explosion-proof, vibration-resistant, intuitive, easy to read, mercury-free, strong and durable in terms of design principle and structure. It is widely used in industries and scientific research departments such as petroleum, chemical industry, machinery, shipbuilding, power generation, textile, printing and dyeing.
2. Main features
Display temperature on site, intuitive and convenient; safe and reliable, long service life;
Various structural forms can meet different requirements.
Working principle
The bimetallic thermometer is based on a bimetallic strip wound into a ring-shaped bend. When one end is heated and expanded, it drives the pointer to rotate, and the working instrument displays the corresponding temperature value.
