GENERAL DESCRIPTION
The DSDXL series offers a digital
interface on a very cost-effective 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.
The DSDXL010D4R device is
available to measure gage pressure
from 0...10 "H

O.
APPLICATIONS
· Medical instrumentation
· HVAC controls
· Pneumatic controls
The DSDXL...4D devices are available
to measure differential pressures from
0...±5 "H
2
O (DSDXL005D4D) to
0...±10 "H
2
O (DSDXL010D4D).
Differential devices allow application
of pressure to either side of the
sensing diaphragm and can be used
for gage or differential measurements.
All DSDXL devices are accurate to
within ±2.5 %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.
ELECTRICAL CONNECTION
+Vs
N/C
Note:
A capacitor of 220 nF is required
between +Vs and GND.
Pin 2 is an internal device connection and
should be connected to ground with a
15 nF capacitor.
It is important to place the capacitors as
close to the pins as possible!
