For applications with lower requirements on the temperature stability of the output-signal we offer
alternative to DS1 the type DS2 as low cost pressure transmitter. The DS2 measures difference-pressure, positive and
negative relative pressure or optionally velocity of flow. The analog output signal is 0-10 V or 4-20 mA. Because
of the piezoresistive cell the transmitter reach a high reliability and precision. They are housed in a robust aluminium
package. This guarantees good EMV-properties.
An individual calibration certificate belongs to every pressure transmitter.

15-30 VDC
DS2-420:
4-20 mA
RB ... 20 up to 400

connections:
electrical:
screw clamps for 0.14 - 1.5 mm2

connection DS2- 010:
plug:
1 : + 24 VDC
2 : output 0 - 10 V
3 : GND
connection DS2- 420:
plug:
1 : + 24 VDC *
2 : output 4 - 20 mA *
* Because of a additional special circuit the transmitter canīt be damaged due to a wrong connection.
That means:
both wires can be changed. Between 2 and GND of the power supply must be connected a resistor RB
... 20 up to 400 at power supply + 24 VDC.
optionally square root output (for measuring velocity of flow):
DS2 can measure the velocity of flow if it is completet with a square root output. Therefor a
measuring blend or a Prandtl-tube must exist or be ordered.
