Nine key factors affecting the accuracy of diffused silicon pressure transmitter

Author:    Source:    Date: 2021-05-25 11:18:12
Precision is the core of the diffused silicon pressure transmitter. The higher the accuracy, the better the quality of the 2088 diffused silicon pressure transmitter. A good diffused silicon pressure transmitter can last longer. Accuracy is the core, quality is the key, but what are the factors that affect the accuracy of diffused silicon pressure transmitters? There are too many uncertain factors that affect accuracy, such as product equipment, human operation, site conditions, and product aging. The following are 9 more common 9 important factors that affect the accuracy of diffused silicon pressure transmitters

   9 key factors affecting the accuracy of diffused silicon pressure transmitter

  1 When freezing occurs in winter, the diffused silicon pressure transmitter installed outdoors must take anti-freezing measures under pressure to prevent the liquid in the pressure port from expanding due to the frozen volume and causing damage to the sensor.

  2. When measuring the liquid pressure, the installation position of the transmitter should avoid the impact of the liquid (water hammer phenomenon), so as to prevent the sensor from being damaged due to overvoltage.

  3. Pass the cable through the waterproof connector (accessory) or winding hose, and tighten the sealing nut to prevent rainwater from leaking into the transmitter housing through the cable.

  4. Prevent debris from accumulating in the duct

   5. When measuring the liquid pressure, the take-out port should be opened on the side of the process tube to avoid sedimentation.

  6. When measuring gas pressure, the pressure port is opened at the front end of the process pipeline, and the transmitter is also installed on the upper part of the process pipeline, so that the accumulated liquid can be easily injected into the process pipeline.

   7. The pressure guiding tube should be installed in a place with small temperature fluctuations;

   8. When measuring steam and other high-temperature media, please connect a condenser such as a buffer tube (coil) to prevent the working temperature of the transmitter from exceeding the limit.
