Why is it important to select a test pressure properly for analog gauges?

Selecting the proper test pressure for analog gauges is crucial primarily to avoid damaging the gauge. Analog gauges are designed to operate within specific pressure ranges, and exceeding these limits can lead to mechanical failure or permanent damage to the gauge itself. If too much pressure is applied, it can result in broken parts, such as the diaphragm or Bourdon tube, leading to costly repairs or replacements and the need to recalibrate the system.

Choosing an appropriate pressure not only preserves the integrity of the gauge but also ensures that it can function correctly for its intended measurements in future tests. This practice ultimately contributes to the longevity of the equipment and maintains the reliability of the data being collected during testing processes.
