Temperature transmitter is an instrument that converts a temperature variable into a transmittable standardized output signal. Temperature transmitters convert physical measurement signals or ordinary electrical signals into standard electrical signal output or devices that can output in the form of communication protocols. A temperature transmitter is an instrument that converts temperature variables into a transmittable standardized output signal, and is mainly used for the measurement and control of temperature parameters in industrial processes. The current transmitter is to convert the AC current of the main circuit under test into a constant current loop standard signal, which is continuously sent to the receiving device
Features of the temperature transmitter:
1. Two-wire output DC4-20mA current signal, strong anti-interference ability;
2. Save the cost of compensation wire and installation of temperature transmitter;
3. Large measurement range;
4. Automatic compensation of cold junction temperature, non-linear correction circuit.
Applications of temperature transmitters:
Usually used with display instruments, recording instruments, electronic computers, etc., widely used in petroleum, chemical, chemical fiber; textile, rubber, building materials; electric power, metallurgy, medicine; food and other industrial fields for on-site temperature measurement process control; especially suitable for computer measurement and control The system can also be used in conjunction with the instrument.
Temperature transmitters make it possible to send a scaleable (4 to 20) mA signal from a Temperature Sensor to a control device without investing in long, expensive runs of thermocouple or RTD wire.
Pyromation carries programmable RTD and thermocouple temperature transmitters that can be mounted in the temperature sensor assembly connection head, or surface mounted using a DIN rail mounting clip. Some units offer a visual digital display that shows the current measured value. All are PC programmable and convert various signals into a scaleable (4 to 20) mA analog output signal. We also carry transmitters programmable with Hart® protocol for various signal inputs. Depending on type, some of Pyromation`s thermocouple and RTD temperature transmitters are UL recognized components and/or FM and CSA approved, including styles that are intrinsically safe and approved for use in hazardous locations.
Pyromation temperature transmitters are used in many demanding industries including Pharmaceuticals, Oil & Gas, Power Generation, Chemical, PetroChemical, and Food and Dairy.
