1) The pressure transmitter should be installed on a vertical or horizontal pipeline without strong vibration.
2) The surrounding environment should not contain impurities that have a corrosive effect on carbon steel, copper, and alloys.
3) For the convenience of maintenance and zero adjustment, sufficient space should be reserved above and on the sides of the equipment.
4) The pressure transmitter and the pressure measurement location should be as close as possible, generally not exceeding 5m.
5) When the measured pressure is zero after installation, the output pressure of the pressure transmitter should be 20kPa, otherwise adjustments should be made.
6) The air source used for the pressure transmitter should be filtered pure compressed air.
Installation precautions for electric Siemens pressure transmitters
1) Installation requirements for measuring gas pressure
When measuring gas pressure, the pressure relief point of the pressure measuring pipeline must be selected in the upper half of the pipeline to prevent liquid accumulation in the pipeline.
A flushing valve should be installed at the front of the B pressure transmitter to prevent liquid or dirt from entering the transmitter.
When installing a pressure transmitter on a pipeline throttling device, the pressure measuring point must be within a 45 ° horizontal rotation from the vertical direction.
2) Installation requirements for measuring steam pressure
The pressure measuring point for measuring steam pressure must be installed in the area within 45 ° above the horizontal line to the vertical line. A gas collector should be installed at the highest point of the pressure measuring point and the gas should be discharged regularly to ensure the accuracy of the transmitter's measurement.
3) Installation requirements for measuring liquid pressure
When measuring liquid pressure, the pressure point must be installed in an area within 45 ° of the horizontal rotation from the vertical line.
4) Installation requirements for measuring the pressure of corrosive media: When measuring the pressure of corrosive media, an isolation device should be installed in front of the pressure transmitter and an isolation liquid should be injected into it.
