Contact temperature sensor

As part of this sensor detects between the measured object with a good contact, so again it is usually called a thermometer. It is by conduction or convection and thermal equilibrium state , it can be directly displayed value represents the case of the measured temperature of the object . Generally, it 's measurement accuracy is relatively high . Within a certain temperature , it is even able to measure the temperature inside the object of each case . However, if the measurement is the movement of objects , the heat capacity of small objects or small target, the measurement results will have a relatively large errors , frequent use of the thermometer Engine Temp Sensor thermometer , resistance thermometers , bimetal thermometers and glass liquid thermometers, etc. and so on. They are in the commercial, agricultural and industrial applications are very wide , even in normal life , people often use these thermometers. In electronics, medicine, metallurgy , defense engineering and food sectors , cryogenic technology is widely applied , and there are strong research on superconducting technology , and now you want to measure the temperature of the low temperature below 120K thermometer has been well development , such as : acoustic thermometer, temperature heat thermometer , vapor pressure thermometer, gas thermometer and temperature and so on. Low temperature thermometer element to smaller size , better stability and reproducibility and accuracy is higher. Carburizing heat resistive glass using a porous sintered high-silica glass to form a low temperature carburization thermometer in one temperature sensing element , which can be used to measure 1.6 ~ 300K temperature within this temperature range .
