Sensors Installation
GENERAL INFORMATIONS
At installation of the sensors, take the following
:
Route sensor lines must be protected against excessive
temperatures.
into
consideration
Route sensor lines must be free of vibrations, but with some
flexibility.
Sensor lines must be without kinks and must not chafe.
The threads of the EGT sensors and pick-up of the coolant
must be greased with Loctite ANTI-SEIZE to ensure
a trouble-free removal (see the tightening torque chart).
Shortcomings in these points can result in false readings,
interruption of lines or the ruin of pick-up lines and sensors.
The sensors are furnished by the supplier with the
pick-up lines of 2m (6.5 foot) length, but can be
extended to the max. length of 4m (13.1 foot).
Thermocouples NiCrNi (type K) must be extended with NiCrNi
thermocouple extension cable only.
Connections must be soldered and insulated, preferably
by a shrink tube.

Never establish the connections by clamping, otherwise there
is a danger of false readings due to the higher contact resistance.
NiCrNi thermocouple cables are available in a specialist store
or from your local Bombardier-Rotax dealer.
All other sensors can be extended with a suitable stranded copper
wire.
While installing the sensors, always bear
in mind that you are dealing with
measuring devices, and handle these
sensitive components carefully.
For any question, please contact your local
Bombardier-Rotax distributor.
