Introduction of Shenzhen Contact Temperature Sensor


The measurement part of the touch temperature probe has prominent contact with the target to be measured, also known as a thermostat.
The thermostat reaches the thermal diffusion through transfer or convection, so that the indication of the thermostat can directly indicate the temperature of the measured target. Generally, the measurement accuracy is high. Within the inevitable temperature test standard, the thermostat can also measure the temperature spread inside the object. But for moving bodies, small targets or targets with small thermal capacity, large measurement errors will occur. Commonly used thermostats include bimetallic thermometers, safety glass liquid thermometers, pressure thermometers, resistance thermometers, and thermistors. And thermocouples. They are widely used in industrial, agricultural, commercial and other parts. People often use these thermometers in daily life. With the extensive use of ultra-low temperature skills in defense engineering, space skills, metallurgy, electronics, food, medicine and petrochemical industries and the study of superconducting skills, ultra-low temperature thermometers that measure temperatures below 120K have been developed, such as ultra-low temperature gas thermometers, Vapor pressure thermostat, acoustic thermostat, paramagnetic salt thermostat, quantum thermostat, ultra-low temperature thermal resistance and ultra-low temperature thermocouple. Ultra-low temperature thermometers require small temperature sensor components, high accuracy, good repeatability and reliability. The thermal resistance of nitriding safety glass made by nitriding and sintering porous high silicon oxide safety glass is a kind of temperature sensor component of ultra-low temperature thermometer, which can be used to measure the temperature within 1.5 ~ 280K standard.
