Other temperature probes (Cowl Temp, CDI Temp, Water Temp, etc.) may be installed using current
aircraft standards and practices (refer to AC 43.13). Make sure these probes do not interfere with the
operation of the engine or aircraft.
2.6 Install the Pressure Transducers:
Install only the Pressure Transducers applicable for your configuration.

Mount the PT-30ABS Pressure Transducer on the inside firewall or in the equipment bay under the aircraft
instrument panel. Use the holes in the bottom plate to mount the PT-30ABS. Only two mounting holes are
required.
An equipment bay can be made from a sheet of aluminum. Any piece of equipment or module used with the
CGR-30P can be mounted on the aluminum sheet using a Nut Plate or Riv-Nut to allow easy installation and
removal. The aluminum sheet is then mounted to the inside firewall of the aircraft (using short spacers) and
should never have to be removed. Many aircraft are designed with an equipment bay.
Connect the aircraft manifold pressure line to the pressure port on the PT-30ABS Pressure Transducer. A
flare or barb fitting may be used to connect these lines. Care should be taken not to put excess pressure on
the flexible line leading to the pressure transducer. Make sure there are no kinks in the flexible
pressure lines.
Note: Many certified aircraft have a very small hole in the manifold pressure line to create airflow back to
the intake manifold. This small flow of air keeps fuel from working its way into the manifold pressure
gauge (or transducer), which can cause damage to the transducer over time.
Note: The PT-30ABS can measure manifold pressure up to 36.0" Hg. For manifold pressures above 36.0"
Hg. use the PT-60ABS pressure transducer.
