XCA Series
The XCA Series of pressure sensors use state of the art silicon
micromachined pressure sensors in conjunction with stress free packaging
techniques to provide highly accurate, amplified, calibrated and
temperature compensated pressure sensors for the most demanding
applications.
When operated from a fixed 5.0 Vdc supply, the XCA gage and absolute
sensors provide a 0.25 Vdc to 4.25 Vdc output (4.0 Vdc Span). The XCA5
Series offers an industry standard 1-6 Vdc output (5 Vdc Span) when
operated from a fixed 8.0 Vdc supply.
All other features are the same for the entire family, incorporating stress
isolation and factory calibration to achieve optimum accuracy in this
industry standard package.

**Note 2:
***Note 3:
****Note 4:
All parameters are measured at 5.0 volt excitation for XCA4 and at 8.0 volt excitation for XCA5, for the nominal full
scale pressure and room temperature unless otherwise specified. Pressure measurements are with positive pressure
applied to Port 2 or Vacuum to Port 1. For absolute devices, pressure is applied to Port 2.
Shift is relative to 25
°C
Measured at ½ full scale rated pressure using BFSL
Proof pressure should not exceed 200 psi and burst pressure should not exceed 300 psi

APPLICATION INFORMATION
MEDIA COMPATIBILITY, WETTED MATERIALS
(Apply clean air dry only)
Port 2
P2 Port:
Media must be
compatible with nylon housing,
epoxy adhesive and silicon.
Port
not used for absolute devices.
Port 1
P1 Port: Dry Gases Only.
Media
must be compatible with epoxy
based adhesive. Dead volume of
0.0102 cubic inches.
PRESSURE COMPATIBILITY
XCA4 Gage and Absolute:
Measures gage pressure
only with positive pressure to port 2. There will be a
small output voltage between the actual offset voltage
and ground proportional to vacuum if applied to port 2.
XCA4 Differential:
Measures differential pressure with
positive pressure to port 2 and negative pressure,
vacuum, to port 1. The offset is set to 2.25 volts at 0
psid. It will change slightly with changes in common
mode (line) pressure. The maximum common mode or
line pressure is 50 psi except for 5 psi and less where
the maximum is 190 psi.
XCA5 Gage and Absolute:
Measures gage pressure
only with positive pressure to port 2. There will be a
small output voltage between the actual offset voltage
and ground proportional to vacuum if applied to port 2.
