Pressure Measurement

Pressure measurement covers analog and digital gauges for local indication, and the pumps and comparators used to generate a known pressure for checking them.

Additel, Druck, Crystal Engineering, DH-Budenberg and Dwyer Instruments make up most of the range, with Enerpac covering hydraulic generation. The first decision is range rather than accuracy: a gauge should normally operate in the middle of its span, so sizing a 10,000 psi instrument for a 500 psi process wastes resolution and sizing too close to the maximum shortens service life. The second is the wetted material and connection, since oxygen service, hydraulic oil and corrosive process fluids each impose their own requirements. Digital gauges add datalogging and a documented accuracy statement, which matters if the reading has to support a calibration record. Send us the working range, the medium and the process connection.
