the supply pressure to the transducer. Also, as an
aid for calibration, a second gauge may be installed
on the transducer to indicate transducer output
pressure.
Connect the nearest suitable supply source to the
0.25 inch NPT IN connection on the filter regulator (if
furnished) or to the 0.25 inch NPT SUPPLY
connection on the transducer case (if the filter
regulator is not attached).
Diagnostic Connections
To support diagnostic testing of
valve/actuator/positioner packages, special
connectors and hardware are available. Typical
connector installations are shown in figure 7. The
hardware used includes a 0.25 inch NPT pipe nipple
and pipe tee with a 0.125 inch NPT pipe bushing for
the connector. The connector consists of a 0.125
inch NPT body and body protector.
Note
If the Type i2P-100 transducer is used
in a valve assembly with a positioner,
no hook-up for diagnostic testing is
required for the Type i2P-100. The
hook-up for diagnostic testing should
be installed at the positioner.
Install the connectors and hardware between the
Type i2P-100 transducer and the actuator.
1. Before assembling the pipe nipple, pipe tee, pipe
bushings, actuator piping, and connector body, apply
sealant to all threads.
2. Turn the pipe tee to position the connector body
and body protector for easy access when doing
diagnostic testing.
