series compact pressure sensors are equipped with eight switchable measuring ranges and with or without
optional display (eight devices in one) and are used for measuring above-atmospheric, below-atmospheric, or differential pressures in air. The
piezoresistive measuring element is temperature-compensated and guarantees a high degree of reliability and accuracy. These pressure transmitters
have a pushbutton for manual zero point calibration and an adjustable offset. Applications of these pressure sensors are in clean room, medical and
filter technology, in ventilation and air conditioning ducts, in spray booths, in large-scale catering facilities, for monitoring filters, for 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. The pressure sensor has eight selectable measuring ranges and therefore, minimizes the diversity of types and
inventory levels while covering a greater range of applications. The differential pressure sensor is supplied including connection set
ASD-06
(2 m
connection hose, two pressure connection nipples, screws).

are equipped with eight switchable measuring ranges, one switching output and one
continuous output, and a display for setting the switchpoint and to display the ACTUAL pressure (eight devices in one, plus differential pressure
switch ⁄ differential pressure monitor, continuous pressure sensor in a single device). The pressure sensor is used for above-atmospheric, below-
atmospheric, or differential pressure measurement in clean air with limit value switching. The piezo-resistive measuring element guarantees a high
degree of reliability and accuracy. Applications of these pressure sensors are in clean room, medical and filter technology, in ventilation and air
conditioning ducts, in spray booths, in large-scale catering facilities, for monitoring filters, for 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.
The pressure sensor has a manual zero point pushbutton and an offset potentiometer for final value and switchpoint correction. Fine adjustment by
the user is possible at any time. A connection set
ASD-06
(2 m connection hose, two pressure connection nipples, screws) is included in the scope
of supply.
