Fusion ofelectronic pressure sensor
and analogue display.
The first fully electroniccontact manometer.
For hygienic areasand viscous media
Compared tomechanical units,the electronicmanometer fea-tures variedoptions for opti-mum adaptationto the application.NO or NC functionas well as set andreset points can beset precisely viathe user menu. Theanalogue outputprovides a current

signal and isscalable using the2-point calibrationfor a certain mea-suring range.More functionsare the adjustabledamping and theuser menu withelectronic lockfunction. To be onthe safe side, thepointer is not visi-ble when the unitis disconnected.
The LED display indicates the currentmeasured value. The user can selectbetween different display units. Incombination with the two touch fields,the alphanumeric display is also usedfor a menu-guided parameter settingof the unit.
Food industry Pharmaceutical industry
In the processindustry mechani-cal contact mano-meters are oftenused because oftheir highly visibledisplay. The elec-tronic “contactmanometer” ofthe series PG com-bines the high visi-bility of a mano-meter display withthe advantages ofan electronicpressure sensor.It withstandsvibrations, dynam -ic load changes,overpressure ortemperature fluc-tuations.
Increase yourprocess safety.
The clearly visible scale features anLED ring which has one LED per tickmark. It shows the adjusted set andreset points. As an alternative, it canbe set as a trend display.
