What is more widely used chemical thermometer?

In the chemical industry, temperature measurement is key link, so often need to use thermometer to chemical, chemical thermometer is not single, but there are many kinds of thermometer used in different chemical production, the user can choose according to their actual production demand. So today is to introduce you to some more widely used chemical thermometer. In a thermometer, pressure type thermometer chemical pressure type thermometer with a small temperature measuring probe, high sensitivity, linear scale, long service life, etc. It can be made into shock, anti-corrosion type, and can realize remote contact signals, heat resistance, 0 10 ma, or 4 20 ma signal. Because of its remote transmission characteristics, usually used in remote temperature measurement are needed. Two of thermocouple thermometer thermometer, thermocouple thermometer chemical sensor is composed of two different materials of metal thread closed loop, the temperature signals into a thermoelectric emfs, measurement range - 270 ℃ ~ 2800 ℃, high precision, wide range, suitable for high [area. Three, bimetallic thermometer chemical thermometer in the bimetallic thermometer is has been widely applied in industrial production and temperature measuring device. It is to put the two kinds of different expansion coefficient of metal welded together, simple structure, economy is durable. Measuring range - 80 ~ 600 ℃, use scope is quite widespread, is suitable for the low temperature.
