DESCRIPTION

The ASDX Series is a Silicon Pressure Sensor offering either

an I²C or SPI digital interface for reading pressure over the

specified full scale pressure span and temperature range.

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 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 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.

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.

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 6 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. For the 12-bit digital output, Table 6 provides the output of the sensor at significant percentages. These

outputs are valid at the rated input voltage of the sensor.

15. The output type defines which communication protocol the sensor uses to communicate. Available protocols are I²C or half duplex SPI (sensor

acts only as a slave). This communication protocol is not field selectable, and must be defined when ordering the sensor.

16. Custom pressure ranges are available, please contact Honeywell Customer Service.

17. The pressure units (inches H₂0, cm H₂0, psi, mbar, bar, kPa) define the units used during calibration and in the application.

18. See Table 5 for an explanation of sensor types.
