WARNING
PERSONAL INJURY
DO NOT USE these

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.
This series is a signal-conditioned version of Honeywell's proven performer
and industry leading SCX series sensor.
This amplified ASCX device is in a package the same as the SCX but it
offers a high level (4.5 V span) output on a very cost-effective basis. This
family is fully calibrated and temperature compensated over a range of 0 C
to 70 C [32
F to 158 F] but can be operated from -25 C to 105 C [-13 F
to 221
F]. 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 (ASCX01) up to 150 psi (ASCX150). The absolute devices (A)
have an internal vacuum reference and an output voltage proportional to
absolute pressure. Differential devices (D) allow application of pressure to
either side of the sensing diaphragm and can be used for gage or differential
pressure measurements.
The ASCX series devices feature an integrated circuit (IC) sensor element
and laser trimmed thick film ceramic housed in a compact solvent resistant
case. It provides excellent corrosion resistance and isolation to external
packaging stresses. The package has convenient mounting holes and
pressure ports for ease of use with standard plastic tubing for pressure
connection.
All ASCX devices are calibrated for span to within 1 % (typically 0.2 %)
of FSO. The devices are characterized for operation from a single 5 volt
supply although sensitivity is ratiometric to the supply voltage and any
dc supply from 5 Vdc to 16 Vdc is acceptable.
The ACSX series requires very low quiescent current compared to other
signal conditioned pressure sensors, thus, this series is ideal for battery-
powered applications.
The 100 microseconds response time makes this series an excellent choice
for computer peripherals and pneumatic control applications.

SPECIFICATION NOTES
Note 1:
Full-Scale Span is the algebraic difference between the output voltage at full-scale pressure and the output at zero pressure.
Note 2:
Maximum pressure above which causes permanent sensor failure.
Note 3:
Sensitivity is ratiometric to supply voltage.
Note 4:
Performance specs are shown at reference conditions. Specifications apply for absolute pressure devices with pressure applied
to Port A. For gage devices, pressure is applied to Port B and Port A is left open for ambient. For differential pressures, Port B
is the high-pressure port. All differential devices feature dual pressure ports and can be used as gage or differential sensors.
For absolute devices, Port B is inactive.
Note 5:
Offset calibration is at the lowest pressure for each given device.
Note 6:
Linearity refers to the best straight line fit as measured for offset, full scale and full-scale pressure.
Note 7:
Temperature errors are the maximum shift over 0 C to 70 C [32 F to 158 F], relative to the 25 C [77 F] reading.
Note 8:
Maximum difference in output at any pressure within the operating pressure range and the temperature within 0 C to 70 C
[32 F to 158 F] after:
a) 100 temperature cycles, 0 C to 70 C [32 F to 158 F]
b) 1.0 million pressure cycles, 0 psi to Full-Scale Span.
Note 9:
Response time for a 0 psi to Full-Scale Span pressure step change, 10 % to 90 % rise time.
