Sensortechnics ASDX030D44R Signal conditioned pressure transducer Datasheet

ASDX Series
Signal conditioned pressure transducers
FEATURES
GENERAL DESCRIPTION
· 0...1 to 0...100 psi,
0...±1 to 0...±100 psi
· Absolute, gage or
differential pressure
· 0.5...4.5 V ratiometric output
· Precision ASIC conditioning
· Temperature compensated
The amplified ASDX offers a high level
(4.0 V span) output on a very costeffective basis. This family is fully
calibrated
and
temperature
compensated using an on-board
ASIC. 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 to 100 psi. The
absolute devices have an internal
vacuum reference and an output
voltage proportional to absolute
pressure. Differential devices allow
application of pressure to either side
of the sensing diaphragm and can be
used for gage or differential
measurements.
APPLICATIONS
· Medical instrumentation
· Barometry
· HVAC controls
· Pneumatic controls
All ASDX devices are accurate to
within ±2.0 %FSS. The devices are
characterized for operation from a
single 5 V supply. The sensor is
designed
and
manufactured
according to standards laid down in
ISO 9001.

It is important to place the
capacitors as close to the pins
as possible!
Pins 4, 5, 6, 7 and 8 are internal
device connections and should
not be connected for any reason!

Specification notes:
1. If maximum burst pressure is exceeded, even momentarily, the package may leak or burst, or the pressure sensing
die may fracture.
2. Full Scale Span (FSS) is the algebraic difference between the output signal for the highest and lowest specified
pressure. Span is ratiometric to the supply voltage.
3. Total accuracy is the combined error from offset and span calibration, linearity, pressure hysteresis, and temperature
effects. Linearity is the measured deviation based on a straight line.
Hysteresis is the maximum output difference at any point within the operating pressure range for increasing and
decreasing pressure. Calibration errors include the deviation of offset and full scale from nominal values.
4. Delay time between sampling and signal change at the output.
5. The smallest change in the output voltage, given any change in pressure.
