PDCR 9X2 WIDE TEMPERATURE RANGE TRANSDUCERS
The PDCR 9X2 type pressure transducers are
based on the same design format as the
general purpose PDCR 900 series, but
configured specifically for operation outside
the standard -20° to +80°C temperature
range and provide high thermal performance
over the operating temperature range.
Type Number and Specification
PDCR 902 - Basic core
PDCR 912 - General purpose
PDCR 922 - General purpose
PDCR 932 - Waterproof/Depth
PDCR 962 - Integral connector
The type numbering system denotes the
following details:
PDCR 9 X 2
Compensated
temperature range
-54° to +125°C

PRODUCT NOTE
INTRODUCTION
Operating Pressure Ranges
350mbar, 700mbar, 1, 1.5, 2, 3.5, 5, 7, 10, 15,
20, 35 and 60 bar gauge or absolute.
Other pressure units can be specified,
e.g. psi, kPa, mH20. For higher ranges refer
to PDCR 330 data sheet.
Excitation Voltage
10Vd.c. regulated to within ±0.1% at
5mA nominal.
Other regulated d.c. excitation levels can be
specified e.g. 5V d.c. giving proportionally
reduced output span.
Output Voltage
50mV for 350mbar range
100mV for 700mbar range and above.
The above outputs are for 10 Volts d.c.
regulated excitation voltage.
Common Mode Voltage
Typically +6V to +8.5V with respect to the -ve
supply at 10V d.c. excitation.
Operating Temperature Range
-54° to +125°C.
N.B.
It is possible to operate PDCR 912 and
PDCR 932 types with pressure media
temperature between -54° to +125°C,
however the vented cable and moulded
termination must be limited to -20° to +80°C
operation.
Temperature Effects
Total error band (T.E.B.) or average
coefficients (% F.S./°C) including thermal zero
shift, sensitivity shift and the thermal
hysteresis (for ranges 700mbar and above):
-54° to +125°C: ±2.5% T.E.B.;
±0.015% F.S./°C
Improved performance e.g.
0° to +50°C: ±0.3% T.E.B.;
±0.006% F.S./°C
-40° to +80°C: ±1.0% T.E.B.;
±0.008% F.S./°C
-54° to +125°C: ±1.5% T.E.B.;
±0.009% F.S./°C
N.B.
The temperature effects are applicable when
excitation voltage regulated as stated.
Sensitivity shift with be affected typically
0.004%/reading/°C per 1% change in
excitation voltage.
For additional specification including
assembly diagram and installation drawings
please refer to PDCR 900 SERIES data sheet.
