TEMPERATURE SHIFT
Amplified pressure sensors are 100% posed to the entire temperature range,
tested to insure that the maximum null the maximum null and sensitivity shift will

NOTES
1. Terminals are labeled on the sensor.
2. Input and output share a common
ground.
3. RL must be greater than or equal to
3000 ohms.

SCALING OF 140PC SERIES SENSORS WITH 8V EXCITATION
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-
videa1-6volt(5VSpan)outputswing. For
example, if supply increases by 50% to12
VDC, the output voltage increases by
50% to 1.5-9 volts (7.5 V Span).

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.
Other scalings available upon request.
