Installation Instructions for the
22PC Series Pressure Sensors
WARNING
PERSONAL INJURY
DO NOT USE these products as safety or
emergency stop devices, or in any other
application where failure of the product could
result in personal injury.
Failure to comply with these instructions
could result in death or serious injury.
GENERAL INFORMATION
22PC Series pressure sensors are four active
element piezoresistive bridges. When pressure is
applied, resistance changes and the 22PC
provides an output signal proportional to the input
pressure.
Gage
pressure is measured with respect to
ambient pressure. When applied pressure
increases, the differential voltage V2 - V4
increases. As pressure decreases, differential
voltage V2 - V4 decreases.
Differential
sensors provide a differential
voltage proportional to the pressure differential
between port P2 and P1. As DP = P2 – P1
increases, differential voltage V2 - V4 increases.
As DP = P2 – P1 decreases, differential voltage
V2 - V4 decreases.

Measured using a 1 mA current
Noncompensated pressure sensors, excited by
constant current instead of voltage, exhibit temperature
compensation of Span.
Constant current excitation has an additional benefit of
temperature measurement. When driven by a constant
current source, a silicon pressure sensor’s terminal
voltage will rise with increased temperature. The rise in
voltage not only compensates for the Span, but is also an
indication of sensor temperature.
SOLDERING
Limit soldering to 315

maximum, with
duration of 10 seconds maximum.
CLEANING
Proper cleaning fluids should be selected, based
on the type of contaminants to be removed.
Honeywell recommends alcohols or fluorinated
solvents. Do not immerse the sensor.
