and industry leading SCX series sensor.
TYPICAL APPLICATIONS
• Medical Equipment
• Industrial Controls
• Pneumatic Controls
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.
