„ Precautions when installing
z Attaching the coupling
The recommended tightening torque when installing the adapter
to the main body of the sensor is 20 N•m. It is recommended to
apply grease to the G3/4 screw part in order to avoid scorching.
z
Grounding of metal parts
The metal parts of the main body, the internal circuits 0 V are insulated.

Other precautions
• Regardless of whether the power
of the device is ON or OFF, do not
touch the main part of the
pressure detector, if the if the
pressure detector is touched,
damage may occur due to static
electricity.
• If using a non-conductive liquid such as oil, and plastic piping
are used, the risk of an offset change will become greater. In
such a case, it is recommended to ground the metal housing.
• In the case that noise causes malfunction, grounding the
metal housing may improve performance.
• After installation, conduct an atmospheric correction by
making the applied pressure the same as regular room
pressure. (Refer to page 10)
• When there is condensation,
separate the sensor from cooling
pipe by at least 30 cm using the
connecting pipe.
