If you are looking to upgrade your cockpit with a new EDM look no further than the EDM 830 manufactured by World leader in EDM’s – J.P. Instruments. For the next couple of years at least, the EDM 830 is going to rule the pack because the EDM 830 through its brilliant full-colour graphical LCD display totally revolutionizes the way aircraft engines are monitored. Despite its small size (probably the smallest aircraft EDM in the market), it easily packs more features, functionality, and information in its onto its LCD screen than any other currently available aircraft EDM on the market. The latest feature addition is the Oil pressure gauge. Being small in size is not the only reason that the EDM 830 can be easily mounted – the 830 incorporates a standard 3-4/8" format that can be mounted vertically (portrait) or horizontally (landscape) orientation. Behind the panel, the EDM 830 only requires 2-1/2". Connect the power supply, correctly plug-in the various cables from the aircraft sensors and you’re done – the EDM 830 is ready to fly when you are. And of course, the EDM 830 is FAA STC/TSO approved and comes with a 3-year warranty. Here’s a short list of the main features and functions of the EDM 830: 1. RPM and manifold pressure with full graphical depiction. - Display includes: RPM, MP, %HP, IAT, CDT, OAT, CAT, OIL 2. Pilot programmable engine parameters. - P, OIL T, CHT, EGT, VOLTS, EGT, DIF, CLD, F FLOW, F USED, F REQD, F ENDUR and F REM 3. Percent Horsepower display. 4. Lean of peak or Rich of peak operation at the touch of a button. - EGT Probes 4 or 6 Probes, CHT 4 or 6 Probes 5. Full featured fuel flow computer system. - Volts, Shock Cooling 6. GPS enhanced fuel management. - LOP/ROP JPI Exclusive Leaning Mode 7. Full EDM scanner functionality. - Fuel Flow (USED, Remaining, GPH Endurance, GPS Destination) 8. When fitting, EDM can be oriented as per pilot convenience and display will auto-configure. - MAP, Oil Temperature, Oil Pressure, OAT 9. EDM 830 can be used in 4, 6, 7, 8 or 9 cylinder engines and Turbocharged engines. - The % HP (Requires OAT, RPM, MAP, & FF). The EDM 830 comes with Power Connector and all required harnesses. EZ Trends software is included. Data recording - 100 hrs Downloadable via USB port. Optional functions of the EDM 830 include: CDT Probes, IAT, CARB Temperature and TIT Accessories available include: Single series fuel flow (with or without) transducer, fuel flow harness (10-04650). These are available for 4 and 6 cylinders aircraft engines too. Also available are the EDM TIT probe with shield and extension wire as also the EDM OIL temp. probe. Little wonder then, the EDM 830 manufactured by J.P. Instruments is amongst the best aircraft EDM’s on the market today. More information here: https://www.jpinstruments.com/shop/edm-8301/ Based on the model of the magneto installed in your aircraft, there are several different models / types of RPM standard sensors for aircraft. The RPM standard sensors you select and use would therefore depend on the brand of magneto in your aircraft. Typical RPM standard sensors (as manufactured by J P Instruments) include: RPM Standard Sensor for pressurized BENDIX 1200 SERIES (JPI part # 10-05459) RPM Standard Sensor for pressurized BENDIX 20 SERIES (JPI part # 10-05460) RPM Standard Sensor for pressurized BENDIX DUAL MAG SERIES (JPI part # 10-05461) RPM Standard Sensor for VENT PLUG SENSOR for BENDIX (JPI part # 10-05651) and, RPM Standard Sensor for VENT PLUG SENSOR for SLICK (JPI part # 10-05652). From the year 2002 onwards, IO-550 magnetos usually have a compatible RPM sensor installed (running on 5v), but you can opt for the better-quality RPM standard sensor manufactured by JPI. Since we can’t write on each and every one of the RPM standard sensors, let us concentrate on the more popular RPM standard sensor for the pressurized Bendix series (manufactured by Teledyne Continental Motors). Being simple in construct, the Bendix Magneto RPM standard sensors is easily maintained and therefore quite cost effective. Also, the Bendix Magneto RPM standard sensors manufactured by J.P. Instruments is highly accurate. If you have just acquired an aircraft of your own and are not sure of the importance of the Aircraft Sensor Systems – here’s what it does: The aircraft has sparkplugs and these require high voltage power. Rather than rely on the aircraft battery, the power to the spark plugs comes from a mini power generator called the ‘Magneto‘ - of which, there are different brands; the Bendix brand being more popular. The Bendix Magneto is a small power generator that has a built-in breaker switch, a transformer and a distribution system to channel the power to the spark plugs. This power generator has a rotating magnet inside and it is important that it rotates at a speed that is within the prescribed range otherwise your spark plugs (and hence the engine) will misfire. To ensure all is well, you need the aircraft RPM Sensor. The RPM standard Sensor plugs directly into the magneto and transmits data to your EDM in the cockpit. It is important to have a good quality RPM standard sensor as it helps identify / eliminate the magneto as the source of engine problem. When fitting your new RPM standard sensor, make sure: • The RPM Sensor is aligned with the correct vent plug of the magneto (if you peep through, you should see the rotating magnet in this hole. If you see a ‘gear’ you’re on the wrong vent). • A 4 cylinder engine should read 3600 rpm, a 6 cylinder engine should read 2400 rpm, a 8 cylinder should read 1800 rpm while a 9 cylinder engine should have an rpm of 1600. A 4 cylinder dual mag engine should have rpm of 1800 and a 6 cylinder dual mag should have rpm of 2400. • The red wire to the RPM standard sensors should be supplying 5v+.
