PT100 4-20mA Hart Temperature Transmitter Overview:
PT100 4-20mA hart temperature transmitter, as a temperature measurement sensor, is usually used together with temperature transducer, regulator and display instrument to form a process control system for direct measurement or control of the temperature of liquid, vapor and gas media as well as solid surface within -200ºC~500ºC in various production processes. The thermal resistor measures temperature by using the characteristic that the resistance itself changes with the change of temperature of substance. When temperature gradient exists in the measured medium, the temperature measured is the average temperature of the medium where temperature-sensing element is located. Although the appearance of all thermal resistors varies widely, their basic structure is roughly similar, generally including such major components as temperature-sensing element, insulation casing, protective tube and junction box.
PT100 4-20mA Hart Temperature Transmitter Features:
* German temperature sensor, with high temperature measurement accuracy.
* Simple installation and a variety of temperature ranges optional.

* German thin-film resistive element, with rapid thermal response speed and reliable and stable performance.
* Good long-term stability, low energy consumption and small size.
* Compression spring-type temperature sensor, with good vibration resistance.
* Automatic compensation of cold end temperature, using non-linear correction circuit.
PT100 4-20mA Hart Temperature Transmitter Application:
* Piping and ventilation system
* Hydraulic and pneumatic system
* Cooling system and heating system
* Water supply and hot water system
* Air conditioning system
PT100 4-20mA Hart Temperature Transmitter Working Principle:
PT100 4-20mA hart temperature transmitter by using the characteristic that the resistance itself changes with the change of temperature of substance. When the resistance changes, the bridge passing through the temperature transducer will produce an unbalanced signal, which is converted into 4-20mA DC signal after being amplified, and then the working instrument will show the corresponding temperature value.
