Pressure Gauge Range Selection Criteria

The maximum operating pressure should not exceed 75 of the full scale range.

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

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. To select the correct pressure range for a gauge where there is dynamic pressure with potential of pulses and surges choose a full scale pressure where the operating pressure occurs in the middle half 50 to 75 percent of. Brass phosphor bronze alloy steel 316 stainless steel monel and inconel. It is important to select a pressure range that is approximately twice the normal operating pressure of the media.

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