DPTM52-5002
2-WIRE DIFFERENTIAL PRESSURE TRANSMITTERS CURRENT OUTPUT
GENERAL
The differential pressure transmitters of the DPTM series are used for measuring differential pressure, positive pressure, and vacuum. The transmitters are suitable for:
•air-conditioning,
•building automation,
•environmental protection,
•valve and flap control,
•filter and blower monitoring,
•fluid and level monitoring, and
•control of air flows.

FUNCTION
DPTM52-5002 Two-Wire Differential Pressure Transmitters are equipped with an integrated piezo-resistive pressure transducer. The pressure to be measured is applied to and thus deflects a thin membrane made of mono-silicon. The membrane's semiconductor resistors (arranged to simultaneously compensate for the temperature response) detect this deflection and generate an electrical output signal. The output signal is converted into a 4…20 mA analog signal

which changes (within the specified error limits) in proportion to the applied pressure.
NOTE: The devices are factory pre-set to pressure range 1 This can be changed (except for +/- models) to pressure range 2 by removing the corresponding jumper (see Fig. 3).
NOTE: The devices are factory pre-set to a response time of 1 second. This can be changed to 100 ms by removing the corresponding jumper (see Fig. 3).
