Features
The B+B pressure modules combine modern sensor technology with
exible signal processing of an ASIC.
The module has a calibrated, analoge voltage output of 0…5 V and also
a digital I²C-interface, which can directly communicate with a microcon
-
troller.
By a precise calibration at 7 measuring points, one can achieve an
outstanding precision and a very low temperature residual error. The
completely processed, calibrated, pressure measured values are made
ready with high resolution which makes simple integration possible with
customer specic products. The calibrated and standard output signal
guarantees simple integration of sub-system in development phase and
enables shortest time-to-market product developments. The probes are
ideally suitable for measurement of static and dynamic relative pres
-
sure in liquids and gases. Typical application areas emerge in the eld
of pneumatics, hydraulics as well as in industrial applications. Besides
the standard variants, customer specic models are also available
e.g. with other operating voltage, special calibration, ratiometric vol
-
tage output and also with digital output signal. Further information on
