order to avoid instrument failure or mal- function.
2. Im portant notice
Unless specified, the transducer must not be used under hydrogen
environment.
3. Safety precautions
Avoid pressure in excess of the allowable overload rating, or the
transducer may explode.
Avoid contact of a projecting object with the sensing surface, or the
latter may crack to result in the transducer' s explosion.
Use the specified tightening torque. Improper tightening torque may
cause the transducer' s explosion.
If excessive pressure could possibly occur, provide protective casing
around the transducer installation, in order to safeguard the operator.
Select sufficiently strong material for mounting screw hole.
Dismount the transducer only after the applied pressure has been
completely removed.
SUS630 (JIS G4303) is used where the transducer contacts a liquid.
Avoid application of the instrument to a corrosive liquid or gas.
4. Handling precautions
Do not disassemble the transducer.
Take care to keep the mount screw from damages.
Protection code is IP52. It should not be used underwater.
No condensing. If it formed condensation, immediately dry.
Avoid pressure on the casing.
The pressure transducer can not be used in vacuum environments.
Keep foreign matters from entering the two holes on the top of casing.
Do not bend the cable at its outlet.
Make sure that the bending radius of cable is longer than 6 times of
a diameter of the cable.
In vibration environment, fix the cable at its outlet and required
portions. Even if the cable is fixed at a distance shorter than 30cm
from the pressure transducer, vibration acceleration should be below
147m/ s (Approx.15G).

Caution
Caution
If the rising time of the dynamic phenomenon to be measured is short,
the total response including the transducer and measuring instrument
in use may be problem.
Before measurement, check their specifications.
5. Mounting
5.1 Using a gasket, mount the transducer. Apply your spanner to the
spanner rest on the connecting screw section or the transducer may be
damaged. Also, turn the cable together to protect the cable from
damage due to twisting.
・ Tightening torque is 60 to 100 N- m.
5.2 Use a new gasket.
5.3 Mount the transducer possibly closest to the pressure source.
5.4 When conduit is used, install a cock or valve between the conduit and
connection portion to easily mount and demount the wire conduit.
6. Connection
6.1 Connect the transducer to a measuring instrument.
6.2 When using a measuring instrument other than KYOWA, connector
plug as follows.
When connected the attached cable, shield wire is not connected to
the case.
6.3 Heat run for 5 minutes or longer before starting the measurement.
