- Do not use voltage higher than 36V on the transmitter, as it may cause damage.
- Avoid touching the transmitter’s diaphragm with hard objects, as this could damage the isolation diaphragm.
- The measured medium should not freeze, as the freezing may damage the isolation diaphragm of the sensor, leading to transmitter failure.
- When measuring steam or other high-temperature media, the temperature should not exceed the transmitter’s maximum operating temperature. Otherwise, a cooling device must be used.
- When measuring steam or other high-temperature media, use a cooling tube to connect the transmitter to the pipeline, transferring the pressure through the tube. When the measured medium is steam, an appropriate amount of water should be injected into the cooling tube to prevent overheating steam from directly contacting and damaging the sensor.
- During pressure transmission, pay attention to the following:
- Ensure there are no leaks at the connection between the transmitter and the cooling tube.
- Open the valve carefully to prevent the measured medium from directly impacting and damaging the sensor diaphragm.
- Keep the pipeline clear to avoid debris buildup that could dislodge and damage the sensor diaphragm.
- Prevent debris from accumulating in the pressure guide tube and avoid exposing the transmitter to corrosive or overheated media.
- When measuring gas pressure, the pressure tapping point should be placed at the top of the process pipeline, and the transmitter should also be installed at the upper part of the pipeline to allow accumulated liquid to flow back into the process pipeline easily.
- When measuring liquid pressure, the pressure tapping point should be located on the side of the process pipeline to avoid sediment buildup.
- The pressure guide tube should be installed in areas with minimal temperature fluctuations.
- When measuring liquid pressure, the transmitter’s installation position should be chosen to prevent liquid impact (water hammer effect) to avoid overpressure damage to the transmitter.
- In winter, if the transmitter is installed outdoors, antifreeze measures must be taken to prevent liquid in the pressure guide tube from freezing and expanding, which could damage the transmitter.
- When wiring, pass the cable through a waterproof connector or flexible tube and tighten the sealing nut to prevent rainwater or other liquids from leaking into the transmitter housing.
- When measuring steam or other high-temperature media, install a buffer tube (coil) or condenser to prevent the transmitter from exceeding its temperature limits during operation.
