PRESSURE TYPE DEFINITIONS

Gauge Pressure Gauge:

Indicates pressure using ambient atmospheric

pressure as the zero datum point.

Compound Pressure Gauge:

Indicates pressure both above and below ambient

atmospheric pressure using atmospheric pressure

as the zero datum point.

Vacuum Gauge:

Indicates pressure below ambient atmospheric

pressure using atmospheric pressure as the zero

datum point.

Absolute Pressure Gauge:

Indicates pressure above zero absolute pressure

(full vacuum).Heise absolute pressure gauges

DO NOT incorporate automatic atmospheric

barometric pressure compensation. The barometric

pressure at the time of use must be set in the

gauge using the external adjustment dial.
