The temperature transmitter corrects the thermal resistance sensor using positive feedback method, and corrects the thermocouple sensor using multi segment line approximation method. There are two display methods. The temperature transmitter displayed on LCD is outputted in a two wire system, while the temperature transmitter displayed on LED is outputted in a three wire system.

　　The technical requirements for temperature transmitters are to use silicone rubber or epoxy resin sealing structures, which are shock resistant, moisture resistant, and suitable for installation and use in harsh on-site environments. Installed on-site in the junction box of thermocouples and thermal resistors, it can directly output 4-20mA, 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 end temperature; High precision, low power consumption, wide temperature range for use in liquid turbine flow meters, 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 testing equipment and instrument panels; 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, graduation number, and range of the transmitter with 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 measured medium temperature, sensor value changes, output current, and percentage ratio of the transmitter; Adopting a silicone rubber or epoxy resin sealing structure, it is earthquake resistant, moisture resistant, and suitable for installation and use in harsh on-site environments.
