The differential pressure sensor DS200 is used to measure small differential pressures in ventilation and air conditioning. As transducer a soft silicone membrane is used, which moves under the influence of a differential pressure measuring spring.
 
The DS200 has four calibrated measuring ranges, which can be selected via a DIP switch. A two-line alphanumeric LCD display shows the measured pressure in the physical unit.

In combination with a differential pressure transducer (orifice plate, venturi or pitot tube), the DS200 also directly display the flow in a pipeline. For this purpose, the differential pressure of the differential pressure transducer is square root and multiplied by an adjustable factor of the differential pressure transducer.

A damping of output signal and display, because of fluctuating measured values, can be adjusted in three stages via DIP switches.

The differential pressure sensor DS200 delivers an analogue output signal of 0/2 ... 10 V or 0/4 ... 20 mA. The supply voltage is 15 ... 30 Vdc or 24 Vac.
