MOUNTING OF STANDARD
TYPE SENSOR
4
ە A sensor mounting bracket MS-DPX and MS-DPX-4
(optional) may be used.
When mounting the sensor with the sensor mounting
bracket, etc., the tightening torque should be 1.2N㺃m
or less.
Note: In case mounting brackets or screws other than the
sensor mounting bracket shown in the figure above
are used, the lengt h of t he screws inserted int o the
pressu r e p ort at t ach men t shoul d b e 5mm or less. If
the length of the screws is longer than 5mm, the
sensor may be damaged.

short-circuit protection circuit. Do not directly connect
a power supply or a capacitive load. When using the
analog voltage output, take care to connect external

Also, when a cable extension is used, volt age drop

PRESSURE UNITS

ە
ە
The pressure unit can be selected as per cust omer's requirement.
In case o f p osi t i v e p ressu re t ype, t h e pressure un i t can b e
changed from International System of Units (SI) 'kPa' or 'MPa'
to 'kgf/cm
2
', 'bar' or 'psi'. In case of vacuum pressure type, the
pressu r e u n it can b e ch an g ed from Int ernat i onal Syst em of
Units (SI) 'kPa' to 'kgf/cm
2
', 'bar', 'psi', 'mmHg' or 'inHg'.
࣭
࣭
When t he pressure unit is changed, the set values
and the measured value are automat ically convert ed.
Please refer to ' SETTING ĭ Initial setting' for
the procedure t o change the pressure unit.
