The EDM 900 alarm consists of three parts; the digital readout changes colour to yellow or red (depending upon intensity of the problem), secondly, the message area will display the error code and finally, just so the pilot does not miss it, RAL light will blink to gain pilot attention.

For accurate temperature data, ensure that the tip of the probe is in the centre of the exhaust stream. When sure that the probe is in the right place, tighten the stainless-steel clamp to a torque of 45 in/Lbs. Cut off the excess strap close to the screw.

The E-Type OAT Probes are obsolete and no longer used. Though, you might still find them in older EGT systems as in vintage aircraft. The E-type probe was usually made using Constanton and Chromel metals.

Each of these Aircraft Sensor System is mounted in the fuel line prior to the fuel distributor or carburettor and, they measure the actual fuel flowing through.

In a turbocharged aircraft, the MAP does not vary with the altitude because the presence of the compressor means the aircraft engine does not have to rely on free-flowing air.

The EDM 950 monitors the aircraft engine parameters roughly 180 times a minute and will warn the pilot the moment any parameter exceeds the pre-programmed limit.

It is easily installed (vertical or upside down or horizontal) and is considered to be amongst the most advanced and accurate piston engine-monitoring instrument.

The analog temperature display are in the form of electronic bar graph i.e one vertical column per cylinder.

The best location therefore, is to place OAT probe under the aircraft wing but sufficiently outboard so as to avoid exhaust heat - the bottom of the fuselage would be an ideal location.

They constantly monitor the health of the aircraft engine and any red-line events are instantly brought to the pilot’s attention via audio-visual alarms.
