The calibratable PREMASGARD

compact pressure sensors with Modbus connection are

optionally equipped with display and are used for measuring

above-atmospheric,

pressures of air. The piezo-resistive measuring element is

temperature-compensated and guarantees high reliability

and accuracy. The pressure transmitters are provided with

a push-button for manual zero point calibration and an

adjustable offset. Applications of these pressure sensors

are in cleanroom, medical and filter technology, at ventila-

tion and air conditioning ducts, at spray booths, in large-

scale catering facilities, for filter monitoring and level

measurement, or for triggering frequency converters. Media

measured with these pressure transducers are air

(non-precipitating), or other gaseous non-aggressive, non-

combustible media. These differential pressure sensors are

supplied including connection set ASD-06 (2 m connection

hose, two pressure connection nipples, screws).

TYPES OF MONITORING:

(A) Below-atmospheric pressure:

P1 (+) is not connected but

open against atmosphere

P2 ( – ) connected to inside of duct

(B) Filter:

P1 (+) connected upstream of filter

P2 ( – ) connected downstream of filter

P1 (+) connected downstream of ventilator

P2 ( – ) connected upstream of ventilator

Pressure connections at the pressure switch

are marked with

P1 (+) for higher pressure and

P2 ( – ) for lower pressure.
