ZT-WB temperature transmitter manufacturer

1.ZT-WB temperature transmitter priceIntroduction
ZT-WB series temperature transmitterIncluding WR series thermocouples and WZ series thermistors, they are new industrial temperature sensors specially designed and manufactured by our factory according to national professional standards for various light industrial machinery such as packaging machinery, clothing machinery, printing machinery, rubber machinery, food machinery, as well as electric furnace industry. They can be used in conjunction with display instruments to measure the temperature of liquids, vapors, gases, and solids in various production processes. They have the characteristics of anti vibration, anti impact, high temperature resistance, and long service life. They are mainly used for temperature measurement and automatic control in the range of -200 to 1300 ℃.
1. Working principle of thermocouple
Connecting one end of a conductor made of two different materials together, when the temperature at the connection point is different from the temperature at the other end of the conductor, a thermoelectric phenomenon (Seebeck effect) will occur inside the conductor due to the difference in electron thermal motion. Thermocouples are temperature sensors that utilize this phenomenon to convert temperature differences into electrical potentials.
The thermoelectric potential of a thermocouple increases with the temperature at the sensing end, and its magnitude is only related to the material of the thermoelectric electrode and the temperature at both ends of the thermocouple, and is independent of the length and diameter of the thermoelectric electrode.
2. The working principle of thermal resistance
Due to the thermal motion of electrons, the resistivity of metal conductors changes with temperature, thereby converting changes in external temperature into changes in technical resistance values. Thermistors are temperature sensors that use this phenomenon to convert temperature differences into resistance values.
