Application

P2V
In the measuring system, the P2V transducer corre­
sponds to HBM's proven passive strain gage absolute
pressure transducers, with a measuring body made from
one piece of material. A high-quality analog sensor ampli­
fier and a digital control for signal correction are also inte­
grated in the enclosure.
All that is seen of this circuitry on the outside is what
looks like an active sensor output with 0.5 to 10 volts (or
a 3-wire current output of 4 to 20 mA.) . The additional
microcontroller monitors the sensor temperature and the
current pressure and generates correction signals, so
that systematic sensor errors such as temperature coeffi­
cients and the linearity deviation can be compensated for
internally. The individual adjustment and correction data
can be transferred to the transducer during production.
HBM's TEDS digital identification system is also available
(compatible with the 1-wire EEPROM DS2433, MikroLan
from Messrs Maxim / Dallas).
Notice
The 0 V power supply (pin 3) and 0 V output (pin 2) lines
are linked internally.
