A Comprehensive Analysis of the Working Principle and Installation Points of Pressure Transmitters

Detailed Explanation of the Working Principle of Pressure Transmitters:

Pressure transmitters, which convert pressure into pneumatic or electric signals for control and remote transmission, play a crucial role in accurately converting physical pressure information captured by sensors, such as that of gases and liquids, into standard electrical signals, such as 4~20mADC. These signals are then received and processed by secondary instruments, such as indicator alarm devices, recorders, or regulators, to achieve measurement, real-time indication, and process control.

Key Points for Installing gauge pressure transmitter:

When installing gas pressure transmitter, several key points must be noted to ensure their accurate and stable operation.

Firstly, the installation location should be chosen in accordance with measurement requirements to avoid unnecessary errors.

Secondly, the electronic circuitry of the transmitter should be protected from external interference to ensure the accuracy of signal conversion. Additionally, attention should be paid to controlling the temperature of the medium to prevent high temperatures from affecting the performance of the transmitter. By following these installation points, the smart pressure transmitter can perform optimally in various application scenarios.

1. When installing the capacitance type pressure transmitter, the connection must be made strictly according to the correct wiring diagram to ensure accuracy.

2. Before use, the EX pressure transmitter should undergo comprehensive testing and metrological verification to prevent damage or vibration during transportation from affecting measurement accuracy.

3. The installation of the pressure transmitter should be kept vertical to the horizontal plane to ensure measurement stability.

4. The measurement point and the installation point should be at the same level to eliminate measurement errors caused by positional differences.

5. To reduce the impact of vibration on the pressure transmitter, vibration damping and fixing devices should be installed to ensure its stability.

6. If the temperature of the measured medium exceeds 60℃, a liquid-filled elbow (condensation loop) should be installed for cooling to prevent high temperatures from affecting the transmitter.

7. During installation, it is essential to ensure good sealing to avoid leakage, especially for flammable, explosive, and toxic media.

8. In industrial applications, it is recommended to use metal tubes to protect the cables leading from the transmitter to ensure its safety and durability.
