The on-site installed temperature transmitter unit in thermocouple and thermistor temperature transmitter instruments is used in conjunction with industrial thermocouples and thermistors. It adopts a two-wire transmission method (two wires serve as a common transmission line for power input and signal output). Convert industrial thermocouple and thermistor signals into 4-20mA and 0-10mA output signals that are linear with the input signal or temperature signal
This temperature transmitter can be directly installed in the junction box of thermocouples and thermal resistors to form an integrated structure. As a new generation of temperature measuring instrument, it can be widely used in industrial sectors such as metallurgy, petroleum, chemical, power, light industry, textile, food, national defense, and scientific research











Adopting silicone rubber or epoxy resin sealing structure, it is shock resistant, moisture resistant, and suitable for installation and use in harsh on-site environments.
Installed on-site in junction boxes for thermocouples and thermal resistors, it directly outputs 4-20mA and 0-10mA output signals. This not only saves expensive compensation wire costs, but also improves the anti-interference ability during long-distance signal transmission;
Thermocouple transmitters have automatic compensation function for cold junction temperature;
High precision, low power consumption, wide temperature range for use, stable and reliable operation;
Widely applicable, it can form an integrated on-site installation structure with thermocouples and thermistors, and can also be installed as a functional module in detection equipment and instrument panels for use;
The intelligent temperature transmitter can communicate with the upper computer through a HART modem or remotely manage, configure, monitor variables, calibrate, and maintain the model, scale, and range of the transmitter through handheld devices and PCs;
The intelligent temperature transmitter can adjust the display direction of the transmitter according to the actual needs of the user, and display the medium temperature measured by the transmitter, changes in sensor values, output current, and percentage
