What is the difference between thermocouple and bimetallic thermometer?
Bimetallic thermometer is very similar to the thermocouple, because the difference between the measured temperature difference, it is more suitable for low temperature on-site testing, measuring a variety of production processes in the range of -80 ℃ - +500 ℃ liquid vapor and gas medium temperature. Industrial high temperature is the use of thermocouple, low temperature, of course, is the most suitable bimetallic thermometer, bimetallic thermometer main component is a two or more metal sheet together with the composition of multi-layer metal, using two different Metal in the temperature change when the degree of expansion of different principles of work. Is based on the formation of ring-like bending around the composition of bimetal. One end of the thermal expansion, driven by the pointer rotation, the working instrument will show the thermoelectric potential should be the temperature value. Industrial bimetallic thermometers The main components are a multilayer metal sheet consisting of two or more metal sheets laminated together.
Bimetallic thermometer in the current domestic use is still very wide and similar products are also very much, bimetallic thermometer with axial, radial, universal type and other head model selection. Bimetallic thermometer probe length can be based on customer Need to customize. Widely used in petroleum, chemical, metallurgical, textile, food and other industries. Bimetal thermometer is a low temperature measurement of the field instrument. Can be directly measured in a variety of production processes in the range of -80 ℃ - +500 ℃ liquid vapor and gas medium temperature. The scene shows the temperature, intuitive and convenient safe and reliable, long life; pull-core thermometer can be a short time to maintain or replace the movement. Axial type, radial type, 135o type, universal type and so on, to meet the needs of a variety of on-site installation.
