Regin DMD-C Anleitung

DMD is a differential pressure transmitter for air and neutral gases. The unit has LED-display and
built-in controlling function. The main application is for pressure control in air handling systems.
Selectable measuring range 0...100, 0...300,
*
0...500, 0...1000 Pa
Pressure signal output 0...10 V and 4...20 mA
*
Controls output 0...10 V

Function
The differential pressure transmitter DMD is based
on microprocessor technology and has a logical
menu system.
Setting of the working range, damping, and zero-
point adjustment is done using buttons under the
lid.
Controlling function
DMD-C has a built-in controller with PID-function.
All parameters are adjustable. The control function
has a 0...10 V DC output signal.
Measuring technique
Pressure measurements are obtained by means of
a sensor that uses a ceramic measuring beam.
The differential pressure affects a membrane that
works directly against the measuring beam. A
thick-film resistor is mounted in the bending area of
the measuring beam. When the measuring beam
bends the resistance value changes. The change
is converted to a proportional output signal via the
built-in electronics.

in controller 0...100/ 300/ 500/ 1000 Pa
Adjustable damping of the measuring signal

Zero-point adjustment

The small number of moving parts in the
transmitter, permits a high degree of accuracy and
short response time. Another important quality is
that the ceramic element has very good long-term
stability.
Adjustable working range
DMD can easily be set between the working ranges
0...100, 0...300, 0...500, 0...1000 Pa.
Electronical damping
The pressure transmitter has electronic damping to
counteract rapid fluctuations in the output signal,
this function is adjustable 0...20 s.
Zero-point adjustment
The output can easily be zero-point adjusted, see
overleaf.
DMD is supplied complete with connection set
containing two pressure outlets and 2 m of hose.
