SS 304 Refrigeration Pressure Gauge 1.8 MPa 63mm Panel Mount Pressure Gauge
63mm 1.8 MPa Panel Mounting Stainless Steel Case Brass Connection Refrigeration Pressure Gauge
Description
As the pressure connection is open to the atmosphere, the pressure gauge is measuring atmospheric pressure. Remember that, by convention, all gauges are calibrated to 0 bar at this pressure. So the needle may indicate 0 but the pressure isn’t zero. The gauge is only comparing the pressure that it is measuring with atmospheric pressure.
The pressure shown on a gauge is called relative or gauge pressure. It is relative to the atmospheric pressure that has a true value of 1.013 bar absolute, we’ll round this to a practical value of 1 bar.
