CAUTIONS

DP2 series is designed for use with non-corrosive gas. 
It cannot be used for liquid or corrosive gas.

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.

Make sure to carry out the wiring in the power supply off
condition.

Take care that wrong wiring will damage the sensor.

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.

Do not use during the initial transient time (0.5 sec.) after the
power supply is switched on.

Do not run the wires together with high-voltage lines or power
lines or put them in the same raceway. This can cause mal-
function due to induction.

Cable extension, using 0.3mm

2

, or more, cable, should be

100m or less overall.

Avoid use of standard type, flat type and light weight type of
sensor in places where steam and dust is excessive.

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.

SETTING OF PRESSURE LEAD
DIRECTION AND PIPING

Standard type

Setting of pressure lead direction

The pressure lead direc-
tion can be changed by
dismantling the pressure
port attachment and
changing the mounting
direction. The tightening
torque of the hexagon-
socket-head bolt (length
9mm or less) should be
0.29N

m or less.

Note: Please make sure to close any unused pressure port with

the hexagon-socket-head plug supplied as accessory.

Flat type, Light weight type

Setting of pressure lead direction

The pressure lead direction can be changed by dismantling
the pressure port attachment and changing the mounting
direction. The tightening torque of the hexagon-socket-head
bolt (length 9mm or less) should be 0.29N

m or less.

Piping

When connecting a cou-
pling to the pressure port,
hold the pressure port
attachment with a 16mm
(Light weight type: 10mm)
spanner and make sure that
the tightening torque is
9.8N

m or less (Light weight

type: 1.47N

m or less). Also, in order to prevent any leakage,

wind a sealing tape on the coupling when connecting.

Piping

When connecting a

or coupling to the pressure
port, hold the hexagonal
part of the pressure port
with a 12mm spanner and
make sure that the
tightening torque is 9.8N

m

or less. Also, in order to prevent any leakage, wind a sealing
tape on the coupling when connecting.
However, sealing tape is not required for North American type
using NPTF 1/8 coupling. (Sealing tape is required if NPT1/8
coupling is used.)

12mm spanner

IP67 type

Piping for pressure measurement inlet port

When connecting a coupling to the pressure measurement
inlet port, hold the pressure port attachment with a spanner
and make sure that the tightening torque is 9.8N

m or less.

Also, in order to prevent any leakage, wind a sealing tape on
the coupling when connecting.

Piping for atmospheric pressure inlet port

If there is a possibility of
water entering into the
sensor enclosure through
the atmospheric pressure
inlet port, connect a tube to
the atmospheric pressure
inlet port through a M5
coupling and extend the
other end of the tube to a
safe place. In this case,
ensure that this end of the
tube does not get clogged.

Fitting of front cover

Insert the bosses on the front cover into the guide holes at
the bottom of the pressure port attachment, and push in the
direction of the arrow to fit the hook.
When removing the front cover, release the hook first.
