Legacy Dynon Avionics-Supplied Coolant Pressure Sensor
(P/N 100411-000)
As of 2012, Dynon Avionics no longer supplies this sensor. For new
installations, use the Kavlico liquid pressure sensors (above). To retrofit an
installation of this legacy sensor with a Kavlico liquid pressure sensor, see
Retrofit Legacy Coolant Pressure Sensor with Kavlico Liquid Pressure
Sensor, above.
For plug-compatible replacement of this sensor in existing installations, purchase
from Aircraft Spruce – 0-30 PSI P/N 10-05471.
For the legacy Dynon Avionics Supplied Coolant Pressure Sensor, if you use Teflon
tape or other seal, ensure the sensor casing still maintains a good connection to
Ground.
The Dynon Avionics-supplied coolant pressure sensor is a 0-30 psi sensor (Dynon Avionics P/N
100411-000). First, mount the pressure sensor to a fixed location using an Adel clamp or other
secure method. The pressure sensor must not be installed directly to the engine due to
potential vibration problems. Next, connect the sensor to the coolant line using appropriate
hoses and fittings. Its pressure port has a 1/8-27 NPT pipe thread fitting; you may need
adapters to connect to the pressure port on your engine. Locate (or drill and tap) the pressure
port along the coolant line. This port must have a pressure fitting with a restrictor hole in it.
This restrictor hole ensures that, in the event of a sensor failure, coolant leakage rate is
minimized, allowing time for an emergency landing.
