ELECTRICAL CONNECTION
Voltage Excitation
NOTES
1. Terminals are labeled on the sensor.
2. Input and output share a common
ground.
3. RLmust be greater than or equal to
3000 ohms.
INTERNAL CIRCUITRY
RATIOMETRICITY
Ratiometricity refers to the output voltage
being directly proportional to the supply
voltage. 140PC sensors in this catalog are
calibrated at 8 VDC supply voltage to pro-
vide a 1-6 volt (5V Span) output swing. For
example, if supply increases by 50% to 12
VDC, the output voltage increases by
50% to 1.5-9 volts (7.5 V Span).
NOTE
The output is not perfectly ratiometric.
See specifications for the degree of error.
NULL AND SENSITIVITY
TEMPERATURE SHIFT
Amplified pressure sensors are 100%
tested to insure that the maximum null
and sensitivity temperature shift does not
exceed the specification. The diagram
below illustrates how null and sensitivity
shift relates to temperature. Note that the
maximum shift occurs at temperature ex-
tremes. Therefore, if a sensor is not ex-
posed to the entire temperature range,
the maximum null and sensitivity shift will
actually be less than the value specified.
This diagram indicates the temperature
shift pertaining to a few listings. Maximum
null and sensitivity shift varies from listing
to listing.

NOTE: 141PC sensors are scaled for vacuum pressure on P2.
142PC sensors are scaled for greater pressure on the P2 side of the chip. Input pressures on
absolute units are applied to the P1 port.
