ASDXACX030PAAA5

P1-P3P4-P6
±
DESCRIPTION
The ASDX Series is a Silicon Pressure Sensor offering a
ratiometric analog interface 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.

Notes:
1. Absolute maximum ratings are the extreme limits that the device will withstand without damage to the device.
2. An external bypass capacitor is required across the supply voltage (Pins 1 and 3 – see Figure 4) as close to the sensor supply pin as possible
for correct sensor operation.
3. 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.
5. The compensated temperature range is the temperature range (or ranges) over which the sensor will produce an output proportional to
pressure within the specified performance limits.
6. The operating temperature range is the temperature range over which the sensor will produce an output proportional to pressure but may not
remain within the specified performance limits.
7. Overpressure is the maximum pressure which may safely be applied to the product for it to remain in specification once pressure is returned to
the operating pressure range. Exposure to higher pressures may cause permanent damage to the product.
8. Burst pressure is the maximum pressure that may be applied to any port of the product without causing escape of pressure media. Product
should not be expected to function after exposure to any pressure beyond the burst pressure.
9. Total error band is the maximum deviation in output from ideal transfer function over the entire compensated temperature and pressure range.
Includes all errors due to offset, full scale span, pressure non-linearity, pressure hysteresis, repeatability, thermal effect on offset, thermal effect
on span and thermal hysteresis. Specification units are in percent of full scale span (%FSS).
10. Full scale span (FSS) is the algebraic difference between the output signal measured at the maximum (Pmax.) and minimum (Pmin.) limits of
the pressure range.
11. Consult Honeywell Customer Service for detailed material information.
12. For AC pressure port configuration, the “pressure” and “reference” ports are reversed.

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.
15. For a digital output, please refer to the ASDX Digital Series.
