Temperature instrument is a branch of the instrument, the temperature of the common instrument has a thermometer, temperature instrument, temperature to send a modulator and so on. Temperature measurement meter according to temperature measuring methods can be divided into two types: contact and non-contact. Often contact thermometer table thermometer table match is simple, reliable, high measurement precision. But because of the temperature measuring element and the demand to stop abundant measured medium heat exchange, help needs a certain amount of time ability to reach thermal equilibrium, so there is temperature measurement delay phenomenon, at the same time restricted by high temperature resistant material, can not be applied to high temperature measurement. Non-contact instrument measuring temperature is through thermal radiation principle for measuring temperature, temperature measuring element does not need to contact with the measured medium, temperature measuring range, not limited by temperature measuring limit, also won't destroy temperature field of the object to be tested, echo ordinary also compare fast; But the object emissivity, measurement interval, dust and moisture, the influence of the outside elements such as the measurement error is bigger. Temperature instrument is usually an instrument and secondary instrument, an instrument is usually: thermocouple, heat resistance, bimetallic thermometer, appeared in situ temperature meter, etc. , secondary instrument is usually appeared temperature meter, temperature inspection instrument, temperature instrument, temperature control meter, temperature transmitter, etc.
