  • Can you measure vacuum using a gauge pressure range

    A gauge pressure range is not suitable for measuring high vacuum pressures, since you can only use a full vacuum range device, which compromises the accuracy and resolution so much that the errors are greater than the difference between full vacuum and the high vacuum reading.

  • Overpressure Protection Devices | Industrial Process Safety

    This set of illustrations shows a pressure/vacuum safety valve in both modes of operation: In each mode, the respective disk lifts up against the force of its own weight to allow gases to flow through the valve. If a greater lift pressure (or lift vacuum) rating is desired, precise weights may be fixed to the top of either disk. Greater weights equate to greater pressures, following the familiar equation \(P = {F \over A}\), where \(F\) is the force of gravity acting on the disk and weight(s
