Siemens temperature integrated transmitter

Siemens temperature integrated transmitterWorking Principle:

Thermocouples or thermal resistance sensors convert the measured temperature into electrical signals, which are then sent to the input network of the transmitter. This network includes relevant circuits such as zeroing and thermocouple compensation. The zero adjusted signal is input to an operational amplifier for signal amplification. The amplified signal is then processed by a V/I converter and output as a 4-20mA DC current; The other path is processed by an A/D converter and displayed in the header. There are two types of linearization circuits for transmitters, both of which use feedback methods. For thermistor sensors, calibrate using positive feedback method, and for thermocouple sensors, calibrate using multi segment line approximation method. Siemens temperature transmitters have two display modes. LCD displays output using a two-wire system, while LED displays output using a three wire system.

Siemens temperature integrated transmitterKey Features:

1. Thermocouple transmitters have automatic compensation function for cold junction temperature;

2. High precision, low power consumption, wide temperature range for use, stable and reliable operation;

3. 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;

4. 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;

5. It 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;

6. The display direction of the transmitter can be adjusted according to the actual needs of the user, and the temperature of the medium measured by the transmitter, changes in sensor values, output current, and percentage can be displayed;

7. 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 performance during long-distance signal transmission.
