Application of intelligent temperature transmitter
Temperature transmitter is a commonly used measuring instrument that uses thermocouple and thermal resistance as the temperature measurement element. Temperature transmitters are mainly controlled by oil, chemical, chemical fiber; textiles, rubber, building materials; electricity, metallurgy, medicine; food and other industrial fields such as field temperature measurement process control; especially suitable for computer measurement and control systems, and can also be used with instruments.
The application characteristics of the temperature transmitter
1. The second-line output is 4-20mA, strong anti-interference ability;
2. Save compensation wires and installation temperature transmitter costs;
3. Safe and reliable, long service life;
4. Automatic compensation for cold end temperature, non -linear correction circuit.
5. Convert the measured environmental temperature to a single -road standard DC voltage or DC current output by linear ratio;
6. Low power consumption and high reliability;
7. Excellent anti -interference ability;
8. Pulling terminal interface, standard guide rail installation;
9. Small volume.
The role of temperature transmitter
Convert a physical measurement signal or ordinary electrical signal to a standard electrical signal output or device that can be output by a communication protocol. The temperature transmitter is a meter that converts the temperature variable into a standardized output signal that can be transmitted, which is mainly used for the measurement and control of the temperature parameter of the industrial process. The current transmitter is to convert the measured main circuit AC current into a constant current standard signal and continuously transport it to the receiving device.
The temperature current transmitter is to transform the signal of the temperature sensor into a current signal and connect to the second instrument to show the corresponding temperature. For example, the model of the temperature sensor in the figure is PT100, then the role of the temperature current transmitter is to transform the resistance signal into a current signal, input the instrument, and display the temperature.
