Temperature Transmitter Features

2023-12-28

Temperature transmitter features:

1. Large measurement range and high precision

2. Small size and light weight

3. Easy installation

4. Strong anti-interference ability

5. Good performance-price ratio

Temperature transmitter applications: widely used in petroleum, chemical, metallurgy, electric power and other fields of pressure measurement and temperature measurement. temperature transmitter selection guide:

One. Select the range of the sensor according to the temperature of the measured medium;

2. Determine the stability of the sensor according to the field environment (such as whether there is vibration or shock, whether it is flammable and explosive) and the characteristics of the measured medium;

Three, according to the use requirements to determine the output signal type (two-wire or three-wire system);

Four. According to the need to choose whether to use diffusion or plug-in installation;

Five. According to the actual need to choose whether you need to show the table.

Selection considerations

1. The transmitter should avoid installation in places with significant vibration or strong electromagnetic interference

2. The shell of the transmitter should be reliably grounded

3. When there is a common ground potential between the input end and the output end

4. To keep the voltage signal of the differential output at ± 5mv

5. Thermocouple compensation must be considered in electrical design.

6. Pay attention to the protection level of the instrument

7. Pay attention to the installation direction of the instrument

8. The unit of the dial scale of the instrument is °C.

9. The graduation numbers of thermal resistance and thermocouple are °C and k respectively

10. Before use, the zero point of the instrument must be checked with a standard platinum resistance tester.

11. Pay attention to regular inspection and verification during use

12. Avoid exposing the sensor to environments exceeding 60°C

13. Avoid direct sun exposure

14. When installing, pay attention to the reliability of the protection wiring

15. If conditions permit, try to use digital display transmitter

16. Try to choose products with RS485 communication interface

17. Try to choose intelligent transmitter with self-test function

18. Do not use in high temperature environment.
