A panel mounting bracket MS-DP-1 is
enclosed to enable simple mounting of
the sensor onto the panel surface, thus
contributing to the total cost reduction.
Light-weight, compact design Can be mounted closely Bright, easy to view two-color digital display
A compact form specifically designed
for mounting on an equipment panel.
It only uses half the space of our
conventional product and provides the
lightest weight in the industry of just
30 g (cables excluded).
Even when you use more than one
sensor at the same time, you can
mount them close together in one hole
to save both space and man-hours.
The digital display is a large, easy-to-
view, and two-color digital display. It is
also functions as an output indicator as
it changes from green to red color
when the output turns ON, enabling
you confirm the output status at a
glance.

Snap-fit connector is used for cable connection
The cable has a snap-fit connector for
easy mounting and removal. The
connector can be easily assembled by
yourself.
Further, the connection by connector
eliminates waste and is eco-friendly.
Usable with a panel thickness of 1 to 6 mm 0.039 to 0.236 in Supplied with a simple-to-mount panel mounting bracket
Since the panel thickness can be from 1 to
6 mm 0.039 to 0.236 in, the sensor can even
be mounted on thick, resin-made panels.
Two types of sensor mounting brackets available
The MS-DP-3 bracket, enabling vertical
mounting, and the MS-DP-4, enabling
horizontal mounting, are available as
options. One-touch mounting of the
sensor mounting brackets is possible
with the panel mounting bracket included
with the sensor.

APPLICATIONS
Checking IC absorption Checking degree of vacuum for vacuum molding Checking reference pressure of device
DP4-50
DP4-50
DP4-52
Can be mounted on a DIN rail
Change-over to analog bar display possible
The sensor can be mounted even on a 35 mm 1.378 in width DIN rail by using the
optional DIN rail mounting bracket (MS-DP-2).
It can be mounted in a narrow space inside of your device.
The pressure changes can be
indicated as a bar display. The analog
bar color reflects the changes in the
output. (The detected pressure value
is displayed in steps of 14 % F.S.
approx.)
Flexible control with four output modes
 100 kPa compound pressure type available
To serve a broad range of pressure
needs, we offer 100.0 kPa, compound
pressure type, in addition to the 0 to
101.3 kPa and 0 to 1.000 MPa types.
Incorporated with the memory bank function
You can store two patterns of set
values. Hence, the setup can be
changed by a single touch.
Selection from six pressure units
The pressure unit can be selected from six
different systems to suit your requirement.
The selectable pressure units differ
with the sensor type. When the
pressure unit is changed, the
measured pressure value and the set
values are automatically converted.
MS-DP-2
High speed response of 2 ms or less
The sensor has a high speed response of 2 ms
or less.
In addition, the sensor has a chattering
prevention function. This allows change-over
of the response time so that fluctuation of the
reference pressure generated during operation
of the large-diameter cylinder and the ejector is
not detected as an abnormal pressure.

Conditions in use for CE conformity
• The DP4 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
(Note) and the following condition must be met to conform
to that standard.
Condition
Wiring
•
Make sure that the power supply is off while wiring.
• Verify that the supply voltage variation is within the rating.
• If power is supplied from a commercial switching regulator,
ensure that the frame ground (F.G.) terminal of the power
supply is connected to an actual ground.
• In case noise generating equipment (switching regulator,
inverter motor, etc.) is used in the vicinity of this sensor,
connect the frame ground (F.G.) terminal of the equipment to
an actual ground.
• If the used power supply generates a surge, connect a surge
absorber to the power supply to absorb the surge.
• Do not run the wires together with high-voltage lines or power
lines or put them in the same raceway. This can cause
malfunction due to induction.
• In order to reduce noise, make the wiring as short as possible.
Others
•
Use within the rated pressure range.
• Do not apply pressure exceeding the pressure withstandability
value. The diaphragm will get damaged and correct operation
shall not be maintained.
• Do not use during the initial transient time (3 sec. approx.)
after the power supply is switched on.
• Avoid dust, dirt, and steam.
• Take care that the sensor does not come in direct contact with
water, oil, grease, or organic solvents, such as, thinner, etc.
• Do not insert wires, etc., into the pressure port. The
diaphragm will get damaged and correct operation shall not
be maintained.
• Do not operate the keys with pointed or sharp objects.

PRECAUTIONS FOR PROPER USE
Peak hold & bottom hold functions
• Peak hold and bottom hold functions enable the display of
the peak value (maximum pressure value) and the bottom
value (minimum pressure value) of the varying measured
pressure.
These functions are convenient for finding the pressure
variation range or for determining the reference for
pressure settings.
•Please note that the peak value and the bottom value data is
erased when it is no longer displayed.
• Since the key-protect information is stored in an EEPROM, it
is not erased even if the power supply is switched off.
• Please take care to remember if the key-protect function has
been set.
• In the sensing mode, press key contin-
uously for 4 sec, or more, and release it
immediately when is displayed.
Key-protect is released and the sensor returns to
the sensing mode.
Release of key-protect
• When the keys are to be operated, make sure that key-protect
is released.
Forced output mode
•In the initial setting mode, if the output mode is set to the
forced output mode ( ), the output is forcibly maintained
at OFF level in the sensing mode, irrespective of Set Value
1 to 3 (P-1 to P-3).
Further, if the keys are operated as per the procedure
given below, the output can be forcibly switched either ON
or OFF without applying pressure at the pressure port. This
is convenient for an operation check of the comparative
output or for an inspection before commencing work.
The diagram below appears when the DP4-50(P) has been used to
set the display to ‘Digital display’( ).
• In the sensing mode, press key to change
to the forced output mode.
• Whenever UP key is pressed, the output state
switches to either ON and OFF alternately.
• Press key to return to the sensing mode.

Memory bank function
• The memory bank function is a function which allows two
types of output to be stored: Set Values 1 to 3 (P-1 to P-3)
and Set Values 4 to 6 (P-4 to P-6).
This make it possible to change set values quickly.
• If the key is pressed in a sensing mode
other than forced output mode, the mode will
change to pressure value setting mode.
• After releasing the mode select key, press the
key again continuously until is
displayed (4 sec. or more).
• Make the setting for Set Values 4 to 6 (P-4 to
P-6). Set Values 4 to 6 (P-4 to P-6) correspond
to Set Values 1 to 3 (P-1 to P-3) respectively.
Refer to 4Pressure value setting on p.786
for details on making each setting.
• Output is kept off at the point where the mode is changed from
another output mode to forced output control mode ( ).
• Even if output has been set to stay on during forced output
control mode, it will be forcibly changed to off at the point
where the mode changes back to sensing mode.

INSTRUCTION MANUAL
Compact Size·Digital Pressure Sensor
DP4 Series
xCAUTIONS
DP4 series is designed for use with non-corrosive gas. It cannot be used
for liquid or corrosive gas.
䢇Use within the rated pressure range.
䢇Do not apply pressure exceeding the pressure withstandability value.The
diaphragm will get damaged and correct operation shall not be maintained.
䢇Make sure to carry out the wiring in the power supply off condition.
䢇Take care that wrong wiring will damage the sensor.
䢇Verify that the supply voltage variation is within the rating.
䢇If power is supplied from a commercial switching regulator, ensure that the
frame ground (F.G.) terminal of the power supply is connected to an actual
ground.
䢇In case noise generating equipment (switching regulator, inverter motor, etc.)
is used in the vicinity of this sensor, connect the frame ground (F.G.) terminal
of the equipment to an actual ground.
䢇Do not use during the initial transient time (3 sec. approx.) after the power
supply is switched on.
䢇Make sure that stress is not applied directly to the connector cable joint.
䢇If the used power supply generates a surge, connect a surge absorber to the
power supply to absorb the surge.
䢇Do not run the wires together with high-voltage lines or power lines or put
them in the same raceway.This can cause malfunction due to induction.
䢇In order to reduce noise, make the wiring as short as possible.
䢇Avoid dust, dirt, and steam.
䢇Take care that the sensor does not come in direct contact with water, oil,
grease, or organic solvents, such as, thinner, etc.
䢇Do not insert wires, etc., into the pressure port.The diaphragm will get dam-
aged and correct operation shall not be maintained.
䢇Do not operate the keys with pointed or sharp objects.
vMOUNTING
䢇Mount the enclosed panel mounting bracket (MS-DP-1) as shown in the fig-
ure below.
The tightening torque should be 0.15N·m or less. Further, tighten both the
right and the left screw gradually and equally, so that the panel mounting
bracket does not tilt.
Sensor mounting bracket (MS-DP-3) which can be mounted on a horizontal
plane and sensor mounting bracket (MS-DP-4) which can be mounted on a
vertical plane are also available.
cPIPING
䢇When connecting a commercial M5 coupling to
the pressure port, hold the flat sides of the pres-
sure port with a 13mm spanner and make sure
that the tightening torque is 1N·m or less.
If excessive tightening torque is applied, the
commercial fitting may break.

⁄1 OUTPUT MODES & THEIR CHARACTERISTICS ⁄2 SETTING
䢇[NO/NC], [Display cycle], [Response time] and [Pressure range] can be
set by the following procedure.
Hysteresis mode
䢇The hysteresis of the comparative outputs can be set arbitrarily by the set
values for ON/OFF control.
Window comparator mode
䢇The comparative output can be turned ON or OFF by a pressure which is
within the set pressure range.
Forced output mode
䢇The comparative output is forcibly maintained at OFF level in the sensing
mode, irrespective of the set values. Hence, it is convenient for only display-
ing the pressure value without using the comparative outputs.
Further, since the comparative outputs can be forcibly switched ON or OFF
with key operation, without actually applying pressure, this mode is suitable
for an operation check or a start-up check.
<Operation example>
䢇The displayed pressure when the pressure port is left open is adjusted
to zero.
䢇[Display mode], [Output mode] and [Unit] are set by the following pro-
cedure.
qIn the sensing mode, press both UP key and MODE
key, simultaneously, to change the mode to the initial
setting mode.
wThe settable digit blinks.
eSetting item changes when UP key is pressed.
rSetting condition of each item changes when DOWN
key is pressed.
qIn the sensing mode, press both DOWN key and MODE
key simultaneously to change to the supplementary set-
ting mode.
wThe setting item and the setting condition are displayed
alternately.
eThe setting item changes when UP key is pressed.

qIn the sensing mode, press MODE key to change to the
pressure value setting mode.
wDisplay shows pressure value setting (P-1) and the
present Set Value 1 alternately. At this time, if Mode key
is pressed for 4 sec. or more, pressure setting value
(P-4) and the present Set Value 4 is displayed alter-
nately.
eChange Set Value 1 or Set Value 4 with UP key and
DOWN key.
rPress MODE key to enter SetValue 1 or Set Value 4.
tIn case pressure value setting (P-1 ) has been set at
Step w, the display shows pressure value setting
(P-2 ) and the present SetValue 2 alternately.However,
if pressure value setting (P-4) has been set, the dis-
play shows pressure value setting (P-5 ) and Set Value
5 alternately.
yChange Set Value 2 or Set Value 5 with UP key and
DOWN key.
uPress MODE key to enter SetValue 2 or Set Value 5.
iSensor returns to the sensing mode and setting is com-
pleted.
⁄4 PEAK HOLD & BOTTOM HOLD FUNCTIONS
䢇Peak hold and bottom hold functions enable the display of the peak value
and the bottom value.
䢇These functions are convenient for finding the pressure variation range or
determining the reference for pressure setting.
⁄5 KEY-PROTECT FUNCTION
䢇Key-protect is a function which prevents any unintentional change in the con-
ditions which have been entered in each setting mode by making the sensor
not respond to the key operations.
⁄3 FORCED OUTPUT MODE
䢇In the initial setting mode, if the output mode is set to the forced output mode,
the comparative output is forcibly maintained at OFF level in the sensing
mode, irrespective of Set Value 1 and 2.
Further, if the keys are operated as per the procedure given below, the com-
parative output can be forcibly switched either ON or OFF without applying
pressure at the pressure port.This is convenient for an operation check of
the comparative output or for an inspection before commencing work.

ting (P-1 ) has been set at Step w, pressure value set-
ting (P-3 ) and Set Value 3, that is automatically set at
the middle between Set Value 1 and Set Value 2, is dis-
played alternately. However, if pressure value setting
(P-4 ) has been set at Step w, pressure value setting
(P-6) and the present Set Value 6, that is automatically
set at the middle between Set Value 4 and Set Value 5,

• In the positive pressure type and the compound pressure type, Set Value 2 (P-2)
can be set only towards the higher pressure side with respect to SetValue 1 (P-1)
and in the vacuum pressure type, it can be set only towards the higher vacuum
side with respect to Set Value 1 (P-1).
• Pressure values can be set and also stored in the order of Set Value 1 (P-1), Set
Value 2 (P-2) and Set Value 3 (P-3), or in the order of Set Value 4 (P-4), Set Value
5 (P-5) and Set Value 6 (P-6).
Notes:
1) In case the output mode has been changed in the initial setting mode, check the
set values of the pressure value setting mode again.
2) After entering Set Value 2 and Set Value 3 and returning the sensor to the sens-
ing mode, if the pressure value setting mode is selected again, Set Value 1 is
displayed. However, after entering SetValue 5 and SetValue 6 and returning the
sensor to the sensing mode, if the pressure value setting mode is selected again,
Set Value 4 is displayed.
3) The set conditions are written and stored into an EEPROM. However, note that
the EEPROM has a life span and its guaranteed life is 100,000 write operation
cycles.
• When the keys are to be operated, make sure that key-protect is released.
