JP Instruments EDM 900 (Primary)

The EDM 900 Primary system allows you to remove your old steam gauge instruments and move up to the most advanced and accurate piston engine-monitoring instrument on the market. Designed to be used both vertical or horizontally, the rear processor is offset to give almost unlimited install choices, and features a long list of user options. TSO’d as a PRIMARY instrument and for quality, the EDM 900 is not just another black box along for the ride. It is a Flight Engineer … a Maintenance Manager … a Backup Instrument. For the price there is nothing that gets close to it. You can almost think of the EDM 900 as your personal flight engineer. It’s always there, working in the background, constantly watching over your engine while you concentrate on flying the aircraft. You can make an entire flight without ever pushing a button, if you so choose. Yet your EDM will be monitoring your engine parameters three times a second and will warn you instantly if any parameter exceeds the programmed limit.

Additions to the EDM 900 that can be purchased are the following and can be checked below to be added:
TIT, IAT, CRB, CRT, Fuel Pressure NON TURBO, Fuel Pressure TURBO, Flush Mount and/or additional Amps/ Volts.
There is an experimental discount - it will come without an STC, below as well.

Accuracy and Resolution, are two of the most misunderstood terms in instrumentation. Because an instrument displays 1 degree increments (resolution) does not mean it is accurate to 1 degree. JPI’s accuracy comes from its linearized thermocouples. Other’ put and estimating straight line through the center of the thermocouple calibration “S” curve. With this method the instrument is accurate at only three points along as the the straight line crosses the “S” curve. Therefore errors of +/- 10′ are quite possible while still displaying in 1degree resolution. Our competition is advertising +/- 1/2′ accuracy at full scale. This would mean that =/-1/2′ of 2000′ (full scale) is +/- 10′; there is a big difference. JPI has found nothing in the Aviation market that compares to our linearized accuracy.

Not only is the EDM 900 TSO’d (available as non TSO’d for experimental aircraft as well), but all of the functions covered by the EDM 900 are TSO’d and STC’d as PRIMARY functions.
