How Does the Temperature Transmitter Work, Output the Temperature Value and Its Function

Ⅰ. The working principle of temperature transmitters


1. The temperature transmitter uses a thermocouple and an RTD as temperature measuring elements. The output signal from the temperature measuring element is sent to the transmitter module, where it is converted into a linear relationship with the temperature of 4-20mA current signal output after voltage stabilization and filtering, arithmetic expansion, non-linear correction, V/I conversion, constant current and reverse protection circuit processing.


2. The temperature transmitter will convert a physical measurement signal or a general electrical signal into a standard electrical signal output or a communication protocol output. A temperature transmitter is a device that converts the surface of a temperature variable into a standardized output signal that can be sent, primarily for the measurement and control of temperature parameters in industrial processes. The main circuit communication current to be measured is transformed into a constant current ring standard signal and transmitted sequentially to the acceptance equipment by the current transmitter.


3. A temperature current transmitter converts the temperature sensor signal into a current signal, which is subsequently linked to the secondary surface and flashes the temperature. For example, the job of the temperature current transmitter in the CZWB series temperature transmitter temperature sensor model PT100 is to convert the resistance signal into a current signal, the input surface, flashing temperature.


Ⅱ. The temperature transmitter's function


The temperature transmitter is completely functional, simplifying the day-to-day operation of diverse temperature applications and decreasing instrument complexity. Diagnostics, safety certification, integrated transient protection, and display choices are among the easy-to-use new features that may help you optimize your process.


The temperature transmitter's enhanced diagnostic features increase the efficiency of your operation and the visibility of your process control.


1. Using a thermal backup mechanism guarantees that the process runs smoothly and that auxiliary sensors can easily take over if the primary sensor fails.


2. Temperature transmitter with sensor drift alarm function tightening control device can detect sensor drift and notify the user automatically.


3. The thermocouple deterioration diagnostic feature allows for speculative protection by monitoring the health of the thermocouple circuit.


4. To improve quality, use the lowest and maximum temperature stakeout feature to record the process and environment's temperature extremes.
