DESCRIPTION
The ASDX Series is a Silicon Pressure Sensor offering a
ratiometric analog output for reading pressure over the
specified full scale pressure span and temperature range.
The ASDX is fully calibrated and temperature compensated for
sensor offset, sensitivity, temperature effects and non-linearity
using an on-board Application Specific Integrated Circuit
(ASIC). Calibrated output values for pressure are updated at
approximately 1 kHz.
The standard ASDX is calibrated over the temperature range
of 0 °C to 85 °C [32 °F to 185 °F]. The sensor is characterized
for operation from a single power supply of either 3.3 Vdc or
5.0 Vdc.
These sensors are available to measure absolute, differential
and gage pressures. The absolute versions have an internal
vacuum reference and an output value proportional to absolute
pressure. Differential versions allow application of pressure to
either side of the sensing diaphragm. Gage versions are
referenced to atmospheric pressure and provide an output
proportional to pressure variations from atmosphere.
The ASDX Series sensors are intended for use with non-
corrosive, non-ionic working fluids such as air and dry gases.
They are designed and manufactured according to standards
in ISO 9001.
