Description
This sensor is used for measuring pressure in hydraulic
circuits. Due to its outstanding characteristics, it is also
ideally suited for use in mobile hydraulics: shock and
vibration resistance, type of protection, resistance
topressure spikes, resistance to temperature shock,
EMCcharacteristics better than 150 V/m. The measurement
principle uses a hermetically welded thin-film measurement
cell, which ensures long-term leak resistance. The sensor
signal can be directly evaluated by a BODAS controller RC.
1) Start of production: Mid of 2016

Characteristics
Output voltage as function of the pressure
The signal output voltage is (up to the nominal pressure)
calculated from the actual pressure as follows:
UOUT = (c1p+c0) US
where
UOUT = Signal output voltage
US= Supply voltage (typ. 5 V)
p= Pressure [MPa]
c0= 0.1
c1= 0.8 / Pn MPa-1
pn= Nominal pressure [MPa]

Pressure
The tolerance for the pressure measurement is given in
%FS = "full scale". FS denotes the sensor nominal pressure
pnenn or the usable range. The relative tolerance is depen-
dent on the pressure and temperature, and increases over
the service lifetime. Here, the service lifetime encompasses
the entire lifetime. The tolerances for new parts are statisti-
cally observed with 3Sigma per manufacturing batch.
Delivery of 100 % sorted products is permitted. After life-
time the tolerance for new parts can broaden to the values
given in the diagram. Here the given tolerances also repre-
sent the 3Sigma limit.

Notes regarding assembly
In the assembly of the connectors, respect the assembly
instructions for plug connections (Y 928 P00 222) and
BDK2.8 contacts (1 928 F00 025).
These assembly instructions are available on request from
Rexroth.
Caution:
In the installation of the connector in the vehicle, observe
the following:
The fixation of the cable harness must be done at a dis-
tance ≤ 150 mm after the outgoing cable unit at the same
vibration level of the sensor.
