Pressure Gauge Range Selection Criteria

If a gauge is not selected considering these criteria it may result in fatigue of the bourdon tube.

Pressure gauge range selection criteria. The full scale pressure of the gauge selected should be approximately two times the intended operating pressure. Failure to select a gauge within these criteria may ultimately result in fatigue failure of the pressure sensor inside the gauge e g bourdon tube pressure sensor elements the pressure sensor elements in gauges are available in a wide variety of materials including. Pressure gauge range selection the pressure gauge selected should have a full scale pressure such that the operating pressure occurs in the middle half 25 to 75 of the scale 12 o clock position is best. Pressure gauge range selection should also permit the desired readable scale increments from a required viewing distance.

It is important to select a pressure range that is approximately twice the normal operating pressure of the media. Failure to select a gauge within these criteria may ultimately result in fatigue failure of the pressure sensor inside the gauge e g bourdon tube pressure sensor elements the pressure sensor elements in gauges are available in a wide variety of materials including. Brass phosphor bronze alloy steel 316 stainless steel monel and inconel. Aim for operational and practical as throttle and well killing manifolds may be installed at both high and low range pressure gauges figs.

Selecting the pressure gauge fully as the pressure gauge s range which may need several gauges especially for 70 mpa and 105 mpa manifolds.
