High accuracy & resolution
High accuracy and resolution
Due to differential pressure sensing, the pressure can be
set with a high resolution of 0.01 kPa.D {1 mmH2O.D}
over a pressure range of 0 to 2.00 kPa.D {0 to 204
mmH2O.D} and, moreover, the detection accuracy is
within ±1 % F.S.
Setting resolution
0.01 kPa.D
{1 mmH2O.D}
Detecting clogging of filter
The clogging of a filter can be reliably detected by
the differential pressure, indicating the time for filter
replacement.

MODE
FUNCTIONS
Bright display and easy key operation
Versatile control with two output modes
Three bright red 7-segment LEDs, 12 mm 0.472 in high,
are incorporated in the compact body. They can be
clearly read not only in a dark place, but also, in a welllit place. Further, initialization or pressure settings can
be easily done with key operation while looking at the
display.
1 Hysteresis mode
The lower threshold value and the upper threshold value
establish the hysteresis of the comparative output.
Pressure unit selectable
The pressure unit can be selected from “kPa” and
“mmH2O” according to your requirement. Further, during
measurement, the pressure unit can be recognized at a
glance from the pressure unit indicator.
kPa
mmH2O
When the pressure unit is changed, threshold values and the
measured pressure value are automatically converted.
2 Window comparator mode
The comparative outputs can be made ON or OFF by a
pressure within the limits set by the upper and the lower
threshold levels.
VARIETIES
Analog current output type: DP-M2A
DP-M2A is incorporated also with the analog current
output (4 to 20 mA). Hence, it is ideally suited for real
time monitoring and multi-point control in combination
with an analog controller (ultra-compact digital panel
controller CA2 series).

PRECAUTIONS FOR PROPER USE
Refer to p.1472 for general precautions.
• Never use this product as a sensing device
for personnel protection.
• In case of using sensing devices for
personnel protection, use products which
meet laws and standards, such as OSHA,
ANSI or IEC etc., for personnel protection
applicable in each region or country.
• The DP-M series is designed for use with
non-corrosive gas. It cannot be used for liquid
or corrosive gas.
Mounting
• The displayed value may vary by 1 digit (0.01 kPa.D
{1 mmH2O.D}) maximum depending on whether the
sensor is installed vertically or horizontally.
• A sensor mounting bracket MS-PE-1 (optional) may
be used. When mounting the sensor with the sensor
mounting
M3 (length 8 mm 0.315 in) screw with washers
bracket, the

less.
Operation
• If setting is impossible even with pressing the MODE
key, verify whether the key-protect function is enabled.
Please note that pressing down on the MODE key for
an extended moment (for 4 sec. or more) will enable the
key-protect function as soon as the key is released. The
key-protect function is set when the display shows
and is released when the display shows
.
• If using the window comparator mode, lower threshold
value (M1) and upper threshold value (M2) should be set
with a difference of 3 digits (0.03 kPa.D {3 mmH2O.D})
or more. No output will be possible with a 0 to 2 digits
difference.

Conditions in use for CE conformity
• The DP-M series is a CE conformity product complying
with EMC Directive. The harmonized standard with
regard to immunity that applies to this product is EN
61000-6-2 and the following condition must be met to
conform to that standard.
Conditions
• The sensor should be connected less than 10 m 32.808 ft
from the power supply.
• The signal line to connect with this sensor should be less
than 30 m 98.425 ft.

Fix tubes on ports securely
Notes: 1) TYGON is registered trademarks of Saint-Gobain K. K.
2) Ensure that excessive pressure is not applied to the pressure
ports. Since this sensor is designed for detecting small pressures,
if excessive pressure or shock is applied to the pressure ports, the
diaphragm (pressure sensing device) in the sensor may get damaged.
3) Please do not compress the tube. If the tube is compressed,
pressure exceeding the rated value may be generated, damaging
the diaphragm (pressure sensing device).
