2. Product description
The differential pressure controller DPC200 measures low pressure of inert gases, par-
ticularly of air.
2.1 Type plate
2.2 Intended use
This device is primarily intended for use with air conditioning systems, room pressure
control or lter control with ebm-papst continuously variable speed fans. It can be oper-
ated solely as a sensor (measuring mode) or closed loop controller for pressure / volu-
metric ow rate control. As analogue output the operator can use a signal from 0 ...10 V
DC. Depending on the settings the signal has different meanings:
1. If the device is used as a pressure sensor, the output signal is proportional to the
measured pressure.
2. As a volume ow sensor the device outputs a square root signal.
3. With closed loop pressure or volume ow 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 inuence of the differential pres-
sure the diaphragm displaces a measuring spring until the spring force compensates for
the pressure pushing on the diaphragm. A contactless differential transformer and suitable
electronics convert this displacement into a continuously variable output voltage signal.
The DPC200 provides two function options:
1. On the one hand it is used as a measuring device. In the measuring mode the differential
pressure is shown on the display, and a proportional 0...10V DC output signal is provided.
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 matches the measured differential pressure with
the setpoint and operates the control variable so that a constant pressure results. The
control variable is given as a 0...10 V DC output signal.
Instead of the quantity ‘differential pressure’ also the quantity ‘volume ow’ can be used
for measuring and for control.
