Product information
The pressure sensors of the series DS-EDM-R are cells with thick-lm
on stainless steel for measuring static and dynamic relative pressure
in liquids or gases.
In opposition to the series DS-ED-R the sensors have a integrated
pressure connector: the 1/4“ connection thread.
The sensor is „all of a piece“ without thick places so no maintenance
of the swimming installation has to be done and no leaks occur. The
thick-lm-on-steel technology in combination with the monolithic
sensor technology allows the measurement range by a factor of 5
to pass before the membrane bursts. The measured medium is only
touched by the stainless steel material (1.4404), resulting in excel-
lent resistance towards aggressive and corrosive media. Therefore,
the sensors are particularly suitable for applications in the eld of
hydraulics, refrigeration technology and for other demanding industrial
applications.The delivery range covers 5 graded measuring variants
in a pressure range from 0 to 100 bar. The sensor itself is designed as
a Wheatstone full bridge, and provides a heavy dependent differential
voltage. The sensor is zero-point and temperature compensated, and
can also be reduced so that it will work in most applications.
