2.2 Intended use
The range of application of the device is e.g. in air conditioning systems for fan control,
for pressure control in rooms or filter control. As analogue output the operator can use
a signal from 0 ...10 V DC. Depending on the settings the device the signal has different
meanings:
1.
Is the device is used as a pressure sensor, the output signal proceeds proportional to
the measured pressure.
2.
As a volume flow sensor the device offers a square root signal.
3.
With pressure resp. volume flow regulation the output signal stands for the control
variable of the PI-control.
2.3 Functional description
A soft silicone diaphragm is used as sensor. Under the influence of the differential pressure
the membrane displaces against a measuring spring until spring force compensates the
pressure charging on the diaphragm. A contactless differential transformer and suitable
electronics convert this displacement into a continuously variable output voltage signal.
The DPC200 combines different functions:
1.
On the one hand it is used as a measuring device. In the measuring mode the differ-
ential pressure is shown on the display, and it is given as a proportional 0...10 V DC
output signal.
2.
Besides the measuring mode the DPC200 also can be operated in a control mode.
Two setpoints can be adjusted in the device and can be selected with the potential free
contact input. The PI-Algorithm settles the measured differential pressure with the
setpoint and operates the actuating variable so that a constant pressure results accord-
ing to the setpoints is set. The control variable is given as a 0...10 V DC output signal.
Besides the quantity 'differential pressure' also the quantity 'volume flow' can be used for
measuring and for regulation.
