Countermeasure: Check if the installation complies with the L<D principle. The leakage hole should face downwards and not be obstructed. For tank installation, ensure that the sensor is flush with the inner wall (flush with the diaphragm). Using front flush process connections with double seals (such as 574, 575) can reduce dead corners.
8.4 Case 4: Measurement still deviates after fine-tuning
Phenomenon: After two-point correction, there is still an error in the middle point.
Reason: The sensor characteristics themselves have good linearity, and fine-tuning only changes the gain and zero point. If the deviation of the midpoint is significant, it may be due to inaccurate reference measurements or unstable actual starting/ending pressure. It is recommended to wait for at least 10 seconds for the pressure to stabilize before performing the demonstration/inputting numerical values.
