Temperature instrument

Product Description:
Temperature meter is a branch of many instruments, common temperature meters are thermometer, temperature recorder, temperature changer and so on. Temperature measuring instruments can be divided into contact type and non-contact type according to the way of temperature measurement. Generally speaking, the contact thermometer table is relatively simple, reliable, high measuring accuracy; However, due to the need for sufficient heat exchange between the temperature measuring element and the measured medium, it takes a certain time to reach the thermal balance, so there is a delay phenomenon of temperature measurement. At the same time, limited by high temperature resistant materials, it can not be applied to high temperature measurement above 1600℃. Non-contact instrument temperature measurement is through the thermal radiation principle to measure the temperature, temperature measuring element does not need to contact with the measured medium, temperature measurement range is wide, not limited by the upper limit of temperature measurement, will not destroy the temperature field of the measured object, the reaction speed is generally fast; However, due to the influence of external factors such as emissivity, measurement distance, soot and water vapor, the measurement error is relatively large.

Field of Application:
In the process of industrial production, temperature is one of the important parameters to be measured and controlled. In the temperature measurement, thermal resistance, thermocouple, bimetal thermometer is widely used, it has the advantages of simple structure, convenient manufacturing, wide measuring range, high precision, small inertia and output signal is easy to transmit and so on. Widely used in power plant, petrochemical and other enterprises cooling water, circulating water, desalination, hydraulic station, air compressor; Petrochemical, electric power medium and low temperature pipeline, equipment surface, generator set and boiler, etc.
