Engines & Probes
Dynon offers a variety of probes to accompany the EMS-D10 instrument with very attractive package pricing. The probes initially offered by Dynon are optimized to support a variety of engines including Lycoming, Continental, Rotax, Jabiru, and ULPower. Probes may also be purchased individually to monitor other types not specifically packaged by Dynon.
Airplanes with existing engine sensors may already be compatible with the Dynon EMS-D10 system. The EMS-D10 was designed with the intention of retrofitting some of the more popular non graphical systems already in existence like Grand Rapids EIS systems. While not 100% backward compatible, replacement costs are minimized to the extent possible. Please review the specifications and sensors charts on this website for additional detail.
Dynon offers a variety of engine probes. These can be purchased individually, but are usually bundled in complete engine packages. Engine probe packages include the wiring harnesses and all probes required. The purchase of an engine package saves approximately 10% over buying its contents separately.
At present, Dynon offers engine probe packages for the following engines:
- EMSKIT-L4C, Lycoming/Continental, 4 Cylinder, Carbureted
- EMSKIT-L4F, Lycoming/Continental, ULPower, 4 Cylinder, Fuel Injected
- EMSKIT-L6C, Lycoming/Continental, 6 Cylinder, Carbureted
- EMSKIT-L6F, Lycoming/Continental, 6 Cylinder, Fuel Injected
- EMSKIT-RTX, Rotax 912, Carbureted
- EMSKIT-RTXis, Rotax 912 iS, Fuel Injected
- EMSKIT-J22, Jabiru 2200
- EMSKIT-J33, Jabiru 3300
The probes, harnesses, and sensors included in each of these kits are detailed in our price list and order form. Additionally, individual sensors and harnesses are available for purchase to accomodate customers that do not have one of the above engines.
A significant advantage of these systems over the standard analog gauges is its ability to continuously monitor each parameter for the pilot and post an alarm anytime an abnormality arises.
To facilitate a wide variety of engines and pilot preferences, each engine measurement is individually setup during the installation process. Pilots can define the color coded operating ranges, whether or not an alarm is generated, and how the alarm behaves once active. Alarm behavior can be set to either be latching, which requires operator acknowledgement, or self-clearing, which lets the alarm remove itself once the offending parameter returns to its normal operating range.
Whenever an alarm condition occurs it is annunciated in a variety of ways:
- A red bar is posted across the bottom of the screen
- The alarm menu is posted across the bottom of the screen
- The measurement value(s) in the alarm state blinks red
- An alarm contact output is closed, which turns on a user-supplied alarm light
- An audible tone is annunciated through the audio panel or intercom when connected
Pilots can deal with alarms in multiple ways. Pressing silence allows all visual annunciations to remain, but the audio tone is muted. Alternatively, the alarm can be fully acknowledged, in which case the audible signal, red alarm bar and external alarm light are all dismissed. Regardless of any action, the alarming measurement value will remain in the blinking red alarm state until the alarm condition is no longer present.
New Programmable Alarms - CHT Shock Cooling & Span Alarms
Current EMS models are now equipped with CHT shock-cooling alarm capability to alert pilots whenever cylinders drop their temperature too suddenly. Separate temperature span alarms are also included that actively monitor across all EGTs & CHTs. Unique temperature span set points can be programmed for lean and normal operating modes.
