REGULATOR
Figure 6. Typical Type i2P - 100 Mounting With Type 67CFR Filter Regulator
between the transducer output and the final control
element should be as short as possible. Transducer
overall dimensions are shown in figure 5. If
weatherproofing is required, mount the transducer
so that the vent can drain. Do not allow moisture or
condensate to collect in the vent.
Note
The vent will not drain properly when
mounted in the downward position.
Pneumatic Connections
As shown in figure 5, all pressure connections on the
transducer are 0.25 inch NPT female connections.
Use 0.375 inch tubing for all pressure connections.
Refer to the vent subsection below for remote vent
connections.
Supply Pressure Requirements
WARNING
Severe personal injury or property
damage could result from an unstable
process if the instrument supply
medium is not clean, dry, oil-free and
non-corrosive. While use and regular
maintenance of a filter that removes
particles larger than 40 microns in
diameter will suffice in most
applications, check with a Fisher Field
office and Industry Instrument air
quality standards for use with
corrosive air or if you are unsure about
the proper amount or method of air
filtration or filter maintenance.
Supply pressure must be clean, dry air or
noncorrosive gas. Use a Fisher Type 67CFR Filter
Regulator, or equivalent, to filter and regulate supply
air. The filter regulator can be mounted on a bracket
with the transducer as shown in figure 6 or mounted
on the actuator mounting boss. An output pressure
gauge may be installed on the regulator to indicate
