Description
High Precision
The model D-10 pressure transmitter with an accuracy of
0.1 % (or 0.05%) has been designed to enable direct
communication to a PC, which is specifically required in the
field of test, calibration and service technology. The electrical
power of the pressure transmitter is taken directly from the
RS 232-interface of the PC.
Digital signal processing
The digital data processing of the precision pressure
transmitter ensures excellent values regarding linearity
and repeatability. System-related temperature errors occurring
usually in pressure measuring instruments are compensated
by the temperature sensor integrated in the process
connection and the digital data processing via
microprocessor. The result is a total temperature error
below 0.1 % in the range of 0 ... 50 °C (32 ... 122 °F).

Software EasyCom
The communication software Easy Com, which is included
in delivery, allows not only the display of pressure and
temperature but also the storage of the measuring data for
pressure and temperature (data logger function) it also offers
an easy adjustment of zero point and span.
Flush version
The model D-11 with a flush diaphragm is particularly suitable
for the measurement of media that is highly viscous,
crystallizing or contains particulates.
