Temperature Transmitter
FEEJOY temperature sensor wireless transmitters adopts thermocouple and thermal resistance as the temperature measuring element. The output signal from the temperature measuring element is sent to the transmitter module. After voltage regulation filtering, operation amplification, nonlinear correction, V / I conversion, constant current and reverse After the protection and other circuits are processed, it is converted into a 4 ~ 20mA current signal with a linear relationship to temperature 0-5V / 0-10V voltage signal, and the RS485 digital signal is output. Our temp transmitter can be used by connected to FEEJOY temp sensor to transmitter the signal elsewhere for monitoring and control purposes.
Introdcution to Temperature Transmitter
If the transmitter consists of two sensors used to measure the temperature difference, there is a given continuous function relationship between the output signal and the temperature difference. It is called temperature transmitter.
There is a given continuous function relationship (usually a linear function) between the output signal of the transmitter and the temperature variable. The output signal of the transmitter produced in the early stage has a linear function relationship with the resistance value (or voltage value) of the temperature sensor.
Advantages of Temperature Transmitter
The multi input temperature transmitter has the advantages of simple structure, lead saving, large output signal, strong anti-interference ability, good linearity, simple display instrument, anti-vibration and moisture-proof solid module, reverse connection protection and current limiting protection, and reliable operation.
The output of the wireless temperature transmitter is a unified 4 ~ 20mA signal; it can be matched with the microcomputer system or other conventional instruments. It can also be made into explosion-proof or fire-proof measuring instruments according to user requirements.

Types and Components of Temperature Transmitter
Transmitter has an electric unit combination instrument series and miniaturized modular type, multi-function intelligent type. The former does not have sensors, the latter two types of transmitters can be easily combined with thermocouples or thermal resistances to form transmitters with sensors.
The integrated thermal resistance smart temperature transmitter is a relatively small temperature transmitter that can be installed in the junction box of the thermal resistance. The integrated temperature transmitter is generally composed of a temperature measuring probe (thermocouple or thermal resistance sensor) and a two-wire solid electronic unit. The temperature probe is directly installed in the junction box in the form of a solid module, thereby forming an integrated transmitter. Integrated temperature transmitters are generally divided into two types: thermal resistance and thermocouple type.
Thermal resistance temperature transmitter is composed of the reference unit, R / V conversion unit, linear circuit, reverse connection protection, current limit protection, V / I conversion unit, etc. After the thermal resistance signal of temperature measurement is converted and amplified, the nonlinear relationship between temperature and resistance is compensated by a linear circuit, and a constant current signal of 4 to 20 mA in a linear relationship with the measured temperature is output after the V / I conversion circuit.
