Pressure Gauge Range Selection Criteria

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 criteria.

Aim for operational and practical as throttle and well killing manifolds may be installed at both high and low range pressure gauges figs. The full scale pressure of the gauge selected should be approximately two times the intended operating pressure. 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. The maximum operating pressure should not exceed 75 of the full scale range.

If a gauge is not selected considering these criteria it may result in fatigue of the bourdon tube. Brass phosphor bronze alloy steel 316 stainless steel monel and inconel.

Pressure gauge range selection should also permit the desired readable scale increments from a required viewing distance.
