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 specic 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 specic 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
