PREMASGARD® PREMASGARD 8148-M

Item No. 1301-8144-0910-20V
EAN 4 251325 617268

The maintenance-free microprocessor-controlled PREMASGARD® 814x - Modbus (series)
with Modbus connection, enclosure made of impact-resistant plastic, enclosure cover with
quick-locking screws, with plastic sinter filter (optional metal sinter filter), with ⁄ without
optional display, is used for precise detection of relative air humidity and temperature in
ducts as well as for measuring differential pressure of air.

Relative humidity (% r.H.) is the quotient of water vapour partial pressure divided by the
saturation vapour pressure at the respective gas temperature. A digital, long-term stable
sensor as a measuring element for relative humidity and temperature guarantees exact
measurement results.

The pressure sensor is used for above-atmospheric, below-atmospheric, or differential
pressure measurement in clean air. 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 (optional automatic zero point calibration) and
an offset potentiometer for final value correction. Fine adjustment by the user is possible at
any time. The delivery includes the connection set ASD-06 (2 m connection hose, two
pressure connection nipples, screws).
