These pressure transmitters with accuracies of 0.1 % (or 0.05%)
have been designed to enable direct communication to a PC,
which is especially required in the field of test, calibration and
service technology. The pressure transmitter's power supply is
taken directly from the RS 232-interface of the PC.
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. This leads to a total temperature
error of < 0.1 % in the range of 0 ... 50 °C.
All wetted parts are made of stainless steel and completely
welded to exclude possible conflict between the sealing material
and the pressure medium. The durable case is also made of
stainless steel and provides IP 67 degree of protection.
The newly developed communication software Easy Com 2.0,
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) as
well as an easy adjustment of zero point and span. The D-1X
pressure transmitters also communicate as working standard
through the optional Easy Cal Light software. With it, simple
calibration for internal test monitoring can be accomplished.
The models of series D-11 with their flush diaphragm are
particularly suitable for the measurement of media that is highly
viscous, crystallizing or contains particulates. Pressure
transmitters with flush diaphragm are available for the pressure
ranges of 0 ... 250 mbar to 0 ... 600 bar.
Pressure ranges from 0 ... 250 mbar to 0 ... 1,000 bar
