This ASDX series is an amplified version of SenSym
ICT’s proven performer and industry leading SDX
series sensor. This amplified ASDX device is in a
package with the slightly larger footprint as the
SDX but it offers a high level (4.0 V span) output
on a very cost effective basis. This family is fully
calibrated and temperature compensated using an
on-board ASIC. These sensors are intended for use
with non-corrosive, non-ionic working fluids; such
as air and dry gases.
Devices are available to measure absolute,
differential, and gage pressures from 1 psi
(ASDX01DN) through 100 psi (ASDX100). The
absolute devices have an internal vacuum reference
and an output voltage proportional to absolute
pressure. Differential devices allow application of
pressure to either side of the sensing diaphragm
and can be used for gage or differential
measurements.
All ASDX devices are accurate to within +/- 2.0%.
The devices are characterized for operation from a
single 5 volt supply. The sensor is designed and
manufactured according to standards laid down in
ISO 9001.

Note 1: Reference Conditions
(unless otherwise noted):
Supply voltage, VS=5.0 ±
0.01 Vdc; Ta=25°C.
Output is ratiometric
within the supply voltage
range (Vs).
Note 2: Span is the algebraic
difference between the
output voltage at the
specified pressure and
the output at zero
pressure. Span is
ratiometric to the supply
voltage.
Note 3: Accuracy is the combined
errors from offset and
span calibration, linearity,
pressure hysteresis, and
temperature effects.
Linearity is the measured
deviation based on a
straight line.
Hysteresis is the
maximum output
difference at any point
within the operating
pressure range for
increasing and decreasing
pressure.
