Guardian Avionics Unveils smartPlane EM100 iPad-Based Engine Monitor for smartPlane System

Posted by on 7/22/2019 to News
Guardian Avionics of Tucson, AZ is pleased to unveil the smartPlane EM100 Engine Monitor, the newest component in the smartPlane line of products allowing aircraft owners to transform their panel into a budget-friendly glass cockpit using the entire line of iPad products from Apple. The smartPlane EM100 Engine Monitor allows owners to connect a wide range of non-proprietary sensors and probes to the EM100, where it converts and relays real-time engine performance and health data to the smartPlane 851 that collects, decodes, and displays the engine data through the smartMFD app on the iPad. Once captured within the smartMFD app, all engine and performance data is collected, logged, and uploaded to the smartCloud online application using 4G or WiFi connections to allow the owner to see valuable long-term trend analysis in an easy to use format.

The smartPlane EM100 may be configured for either 4-cylinder or 6-cylinder piston engines and is able to monitor the following parameters:
  • Exhaust Heat Temperature (EGT) - up to six cylinders
  • Cylinder Heat Temperature (CHT) - up to six cylinders
  • Turbine Inlet Temperature (TIT) - up to three inputs
  • Outside Air Temperature (OAT)
  • Internal Inside Air Temperature (IAT)
  • Oil Temperature (OT)
  • Oil Pressure (OP)
  • Fuel Pressure (FP)
  • Fuel Levels (FL) - up to four tanks
  • Fuel Flow (FF) - up to two inputs
  • Revolutions Per Minute/Tachometer (RPM)
  • Manifold Pressure (MP)
  • Shunt for AMP Meter
  • Voltage Input Monitor
Unlike many engine monitors that use proprietary probes and sensors, the EM100 can be configured with sensors and probes commonly available through popular aircraft parts retailers. The collected data is transmitted to the smartPlane 851 via high speed RS232 to give instantaneous readouts through the easy-to-understand user interface on the smartMFD app for iOS.

“When speaking with our customers, we found that everyone needed a better engine monitor solution.” said Ash Vij, President of Guardian Avionics. “Though we still work with many engine monitor manufacturers to collect and transmit engine data to smartPlane, we felt it was time to give owners a lower cost choice that gets the job done without breaking the bank… and the EM100 paired with the smartPlane 851 is that choice.”

Currently available for the experimental/homebuilt market, the EM100 must be paired with a smartPlane 851 as a package. The smartPlane 851 is currently approved for installation under the FAA NORSEE (Non-Essential Safety Enhancing Equipment) program for Part 23 Certified Aircraft and the EM100 will be submitted for consideration later in 2019.
