Differential pressure sensor for gaseous media
Type:
DSG...
Equipment / Functions
Sensor with a membrane system suitable for measuring differential or
negative pressure of non-aggressive gas. The differential pressure to be
measured takes effect on a silicone membrane, changes in position of
which are compensated by a measuring spring, dependent on the
degree of travel. Changes in position of the membrane are detected by
a differential transformer and converted into an output signal of 0-10 V
by an electronics unit in SMD technology.
The differential pressure sensor supplies an output signal (0-10 V) when
the pressure at the “+” connection exceeds the pressure at the „-”
connection.
Examples of applications in conjunction with controllers for fans:
• Pressure control for central extraction systems and variable air
volume systems (VVS)
• Air volume control together with centrifugal fans (by means of a
measuring device in the inlet duct)
