Understanding Jpi Engine Monitors: Fuel Pressure Visibility

JP Instruments provide engine monitoring and analyzers for aircraft. The JPI EDM-350 Engine Monitoring System is intended for installation in experimental aircraft only. The basic kit includes: EGT, CHT, CLD, DIFF, USB, and Data Record. The full package includes the P5-connector, which has the capability of AMPS1, fuel pressure, fuel level/tanks, and volt2. The EDM-960, meanwhile, is a twin primary twin-engine management system that takes the best from JPI's EDM-760 and adds total engine display monitoring, including tach, % horsepower, Hobbs, manifold pressure, EGT, CHT, oil pressure, oil temp, fuel flow, outside air temp, volts, and amps, plus optional fuel pressure, fuel quantity, and turbine inlet temp.

The EDM-960 Twin Primary engine monitor displays fuel pressure

The EDM-960 Twin Primary engine monitor is a flagship engine monitor from JP Instruments. It is a certified primary flight instrument that can be used to replace old steam gauge engine instruments. The EDM-960 is an advanced and accurate piston engine-monitoring instrument that offers a long list of user options. It can be thought of as a personal flight engineer, constantly monitoring the engine while the pilot concentrates on flying the aircraft. The engine conditions are monitored four times per second, and the pilot is instantly warned if any measurement exceeds the programmed limit.

The EDM-960 collects and displays data in a useful way. It can be used to monitor engine temperatures, voltages, adjust the fuel/air mixture, and diagnose engine malfunctions. It is the latest graphic engine analyzer from JP Instruments, and it takes the best from their EDM-800 and adds total engine display monitoring including Tach, % Horsepower, Hobbs, Manifold Pressure, EGT, CHT, Oil Pressure, Oil Temp, Fuel Flow, Outside Air Temp, Volts, and Amps.

The EDM-960 also offers several optional features, including Fuel Pressure, Fuel Quantity, and Turbine Inlet Temp. Each individual engine display has a variable scale and alarm limit that can be customized to fit the particular airplane. The EDM-960 has internal memory that records all engine parameters, which can be recalled and displayed on a computer to keep track of the engine's health. This allows for easy post-flight data retrieval and analysis.

The EDM-960 is a comprehensive and advanced engine monitoring system that provides valuable data and insights to help pilots ensure the optimal performance and safety of their aircraft.

The EDM-350 Engine Monitor has optional fuel pressure functionality

The EDM-350 Engine Monitor is an advanced and accurate piston engine-monitoring instrument. It is designed for experimental aircraft installations only and is not meant for certified aircraft install. The EDM-350 is not just another black box; it is a flight engineer, maintenance manager, and backup instrument all in one.

The basic kit includes:

• EGT (Exhaust Gas Temperature)
• CHT (Cylinder Head Temperature) probes and harness
• CLD (Shock Cooling on "All" Cylinders)
• DIFF (Engine Health)
• USB (Data Port built-in)
• Data Record (600 Hrs. at every 6 sec)
• EZTrends (Graphing software, including Google Earth Location)

The EDM-350 is a compact system (3.5″ square) that can be customized with 17 options, including FF. It constantly watches over your engine parameters three times a second and will instantly warn you if any parameter exceeds the programmed limit.

The EDM-800 engine monitor can be customised to include fuel flow

The EDM-800 engine monitor is a cost-effective solution for monitoring your engine. It is one of the most advanced and accurate piston engine-monitoring instruments on the market. The EDM-800 monitor has been installed in thousands of cockpits, making every flight safer.

The EDM-800 can be customised to include fuel flow. It comes standard with fuel flow (201B or 231 Transducer is included), CHT (probes included), EGT (probes included), RPM (sensor included), MAP (sensor included), OAT (probe included), flight data memory (can store up to 25 hours of engine data), EzPlot (download software), data cable, and an RS232 interface connection to any GPS navigation system.

The EDM-800 has all the advanced functions of the EDM-700 but incorporates some new features like horsepower percentage and manifold pressure. The percentage of horsepower being used and RPM are displayed at the top of the EDM display. This allows pilots to be sure they are within the horsepower limits of their engine, which can be quite a task in IFR conditions.

The EDM-800 also includes hands-free, automatic scanning; all programming is done from the front panel; LeanFind™, which finds the first and last cylinder to peak with true peak detection and eliminates false peaks; displays both the leaned temperature below peak and peak; battery voltage with alarm; 24 programmable alarm limits; DIF low to high EGT with alarm; EGTs to stable 1°F resolution; shock cooling monitored on every cylinder; a user-selectable index rate; fast response probes; non-volatile long-term memory; and FAA approval as primary temperature instruments for CHT, OIL, TIT, turbine inlet temperature, outside air temperature, compressor discharge temperature, and carburetor temperature.

The EDM-930 Primary engine monitor can be used as a replacement for old engine gauges

The EDM-930 has a large, sunlight-readable LCD display and offers a long list of user options. The monitor can be used to monitor engine conditions, such as fuel quantity, fuel flow rate, and total fuel consumed. It also provides alerts if any measurements exceed the programmed limit. This can help improve situational awareness and engine performance and provide peace of mind while flying.

The EDM-930 is easy to install and can be directly mounted into the panel, replacing old steam gauge engine instruments. It is a certified primary flight instrument and can help free up valuable space in the cockpit. With the EDM-930, pilots can have improved fuel economy, reduced maintenance costs, and extended engine life.

The EDM-930 is a reliable and accurate piston engine-monitoring instrument that constantly watches over the engine while the pilot concentrates on flying the aircraft. It is a valuable tool for any pilot looking to improve their flight experience and aircraft performance.

The EDM-790 Twin Engine Monitor has a sunlight-readable LCD screen

The EDM-790 is the most advanced and accurate twin piston engine-monitoring instrument on the market. It is TSO'd for quality, meaning it has been tested and Technical Standard Ordered by the FAA. This monitor is not just another black box; it is a flight engineer and maintenance manager. It constantly watches over your engine while you concentrate on flying the aircraft.

The EDM-790 has plenty of options to customise exactly what you require. The round rear processor is offset to allow for easy horizontal installation in any panel. The monitor has two buttons that address all the programming functions, and it can be programmed from the front panel. It also has 29 alarms, including EGT Differential, Alternator Voltage, Fuel Flow, and Shock Cooling.

The EDM-790 is a cost-effective and compact advisory EDM. It is the most versatile twin-engine EGT/CHT analyser on the market and will automatically find the first EGT to peak. It will graphically display each cylinder EGT and CHT while simultaneously displaying those cylinder temperatures digitally. Aircraft voltage is also displayed digitally, as well as optional TIT, OAT, and oil temperatures.

The EDM-790 is a valuable tool for pilots, providing timely and responsive data that makes the difference between guesswork and really understanding what is going on in their engines.
