Features
The pressure sensor with digital I²C interface of the series DRTR I²C
transmit the measured value as a calibrated and temperature-compen
-
sated signal. The product range covers 18 graded variants for absolute
and relative pressure in the pressure range from vacuum to 100 bar
full scale (See table). Through a precise calibration of 7 measurement
points at 3 different temperatures, it achieves outstanding precision and
very few temperature errors. Depending on variant, the sensors are ide
-
al for measurement of static or dynamic absolute pressure, or relative
pressure in liquids and gases.
Typical applications for his sensor in the elds of pneumatics, hydraulics
as well as industrial applications. Another eld of application is the mea
-
surement of liquids such as motor oil or fuel in vehicles. The robust sensor
housing made of stainless steel with protection class IP65 has a ¼“ exter
-
nal thread media connection. With the help of an port adapter (accessory),
this allows the pressure sensor to t different gauge ports from ⅛“ to ½“.
The electrical connection is made via the digital I²C interface. A custom
addressing of the transmitter is possible from factory to customer. It is
then possible to use multiple transmitters on the I²C bus.
