1. Callin g th e o p erato r' s atten tion
The following cautionary symbols and headlines are used to invite the
operator' s attention. Be sure to observe the accompanying precautions in
order to safeguard the operator and preserve the performance of the
instrument.
Improper handling can cause serious injury to the
W arn in g
operator.
Improper handling can cause deleterious effects to
Cau tio n
the operator' s body.
Cautions are given to invite the operator' s
Cau tion
attention, in order to avoid instrument failure or
mal- function.
2. Im p o rtant n otice
Unless specified, the transducer must not be used under hydrogen
environment.
3. Safety p recau tio n s
Avoid pressure in excess of the allowable overload rating, or the
instrument can 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 transducer to a corrosive liquid or gas.
Do not use PG- 200KU to PG- 500KU for endurance / fatigue tests.
The PG- U have air vent screw with slot. Avoid using for a long- term
measurement of gas pressure if much importance is attached to the
stability of output in a minute range.

4. Han d lin g precau tio n s
Cau tio n
Do not disassemble the transducer.
Take care to keep the liquid- contacting part and mount screw from
damages.
Protection code is IP54. It should not be used underwater.
No condensing. If it formed condensation, immediately dry.
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.
Mount the transducer possibly closest to the pressure source.
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. Mo u n tin g
5.1 Using a gasket, mount the transducer. Apply your spanner to the
spanner rest on the connecting screw section (Flat- to- flat 14mm) or
the transducer may be damaged. Also, turn the cable together to
protect the cable from damage due to twisting.
・ Recommended tightening torque is 30 N- m.
・ Allowable maximum tightening torque is 60N- m.
5.2 Use a new gasket.
5.3 A seal tape may be tied around the screw for sealing.
5.4 If the measurement object fluid is a liquid, allow the liquid to enter into
the pressure chamber by loosening the needle screw provided on the
transducer, thereby letting contained air go out.
・ Tightening torque for the needle screw is 0.5 N- m.
5.5 When conduit is used, install a cock or valve between the conduit and
connection portion to easily mount and demount the wire conduit.
