PRECAUTIONS FOR PROPER USE

Refer to p.1566 for general precautions.

• A sensor mounting bracket

MS-PE-1 (optional) may

be used. When mounting the sensor with the sensor

mounting

bracket, the

tightening

torque

should be

0.5 N·m or

less.

• The displayed value may vary by 1 digit (0.01 kPa.D

sensor is installed vertically or horizontally.

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

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

from the power supply.

• The signal line to connect with this sensor should be less

Piping

• Apply higher pressure to the Hi-port and lower pressure

to the Lo-port.

• Use flexible tubes (silicone tube etc.) that can fit the

tubes should cover more than half the length of the

pressure ports.

Fix tubes on ports securely

Flexible tube (Silicone tube etc.)

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).

• 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.
