What is the temperature transmitter used for？
Temperature transmitter is a commonly used measuring instrument, using thermocouple and thermal resistance as temperature measuring elements. Temperature transmitters are mainly used in on-site temperature measurement process control in petroleum, chemical, chemical fiber; textile, rubber, building materials; electric power, metallurgy, medicine; food and other industrial fields; especially suitable for computer measurement and control systems, and can also be used with instruments.
Application characteristics of temperature transmitter
1. Two-wire output 4-20mA, strong anti-interference ability;
2. Save the cost of compensation wire and installation of temperature transmitter;
3. Safe and reliable, long service life;
4. Cold junction temperature automatic compensation, nonlinear correction circuit.
5. Convert the measured ambient temperature into a single-channel standard DC voltage or DC current output in a linear proportion;
6. Low power consumption and high reliability;
7. Excellent anti-interference ability;
8. Plug-in terminal interface, standard rail installation;
9. Small size.
The role of temperature transmitter
It is a device that converts physical measurement signals or ordinary electrical signals into standard electrical signal output or can be output by communication protocol. A temperature transmitter is an instrument that converts a temperature variable into a transmittable standardized output signal, and is mainly used for the measurement and control of industrial process temperature parameters. The current transmitter converts the AC current of the main circuit under test into a standard signal of constant current loop, and sends it to the receiving device continuously.
The temperature current transmitter converts the signal of the temperature sensor into a current signal and connects it to the secondary instrument to display the corresponding temperature. For example, the model of the temperature sensor in the picture is PT100, then the function of the temperature current transmitter is to convert the resistance signal into a current signal, input the instrument, and display the temperature.
