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).
