DESCRIPTION
The ASDX Series is a Silicon Pressure Sensor offering either
an I
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.
POTENTIAL APPLICATIONS
Flow calibrators
Ventilation and air flow monitors
Gas flow instrumentation
Sleep apnea monitoring and therapy equipment
Barometry
Pneumatic controls
HVAC

... Ratiometricity of the sensor (the ability of the output to scale to the input voltage) is achieved within the specified operating voltage for each option. Other custom supply voltages are available, please contact Honeywell Customer Service. 4. The sensor is not reverse polarity protected. Incorrect application of excitation voltage or ground to the wrong pin may cause electrical failure. ...

... Future Option Notes: 13. Other package combinations are possible, please contact Honeywell Customer Service. 14. The transfer function limits define the output of the sensor at a given pressure input. By specifying the output signal at the maximum (Pmax.) and minimum (Pmin.) limits of the pressure range, the complete transfer curve for the sensor is defined. See Figure 2 for a graphical representation of each calibration ...
