According to research and study done about sensors or probes, there has been a conclusion that an Engine monitor is just as good as its own probe. This is the reason why various different electronic companies are daily adapting to trends and taking probe manufacturing very serious. An Exhaust Gas Temperature (EGT) probe is a temperature detector that is mounted on exhaust or turbine that relies on thermocouples and therefore it does not require electricity for it to work. A thermocouple is a temperature sensor that is made up of 2 different types of wires that are joined at some point that measures the temperature temperatures in Celsius or Fahrenheit. Outstanding Features of an EGT Probe The following are some of the characteristics of a genuine Exhaust Gas Temperature: • It has a voltage display – an EGT which is single channeled can measure battery voltages of at most 30V which is designed with a programmable alarm that senses high or low voltages, failure in drive belts or faulty batteries. • Has a settable high alarm • Time display meter – this determines the actual time of ignition • It has a service-interval reminder which is inbuilt • It contains both an audible and a LED visual alarm – the audible one can be turned on or off when viewing something while the visual one grows red at an occurrence of an alarm condition • External alarm output that’s for remote indicators • Have LCD that have graphics that are sunlight readable • It has a high voltage protection for harsh environments vehicles and also has voltage reversal Basic Layout of an EGT When you see an EGT you will see the following: • An Audible alarm • LED alarm • A harness – it connects power, thermocouple and external alarm • Down button – adjust the contrast • Menu button – enables you to access the menu system • Up button – increases the contrast to maximum • An LCD that displays the graphics How Does an EGT Really Work? The thermocouple is the heart of EGT. When the temperature increases at its junction, the metals that meet expand producing electrical pulses. Basically, the level of voltage being generated by these pulses is dependent on the type of metal of thermocouple and the amount of heat. The sensor is usually connected to an EGT Gauges that registers the level of temperature that is generated during the throttle or normal functioning of the engine. If there is damage the red Led light will glow. Just know the lower the ETG the more efficient is your engine. In conclusion, an EGT Probes is one of the most important sensors that can warn you as a driver in situations that can damage your engine and will actually guide you on the level of fuel to use. However, it is advisable that you don’t use excess EGT which can destroy your engine.

An aircraft RPM censor is one of the most important instruments inside of an aircraft. This specific instrument measures the RPM of the Bendix in the Magneto, or the Bendix inside the Slick Magneto. More recently, they have been used in the Dual Magneto, but this is not a popular application. The Bendix Magneto can easily be repaired if something goes wrong with it. Typically, you can tell there is something wrong with the Magento by the report sent back from the sensor. Since aircraft is not a popular focus of manufacturers, the most popular options are made by J.P. Instruments. What Does the Magneto Run Off of? The Magneto does not run off of the aircraft's battery. Instead, the power to the magneto comes from the spark plugs, which work like a miniature generator. The Bendix Magneto acts as a small generator would, but inside of the aircraft. It also serves as a transformer, a breaker switch, and a distributor guide, which provides a high amount of power back to the spark plugs. The RPMs are relayed into the cockpit and read by a sensor. The pilot is able to gauge the function of the components it is attached to, to ensure that the aircraft is operating normally. Why Do You Need an RPM Sensor? The RPM sensor inside of the aircraft is essential to the safety of flying your plane. Any sudden drop in RPMs on the sensor Digital Gauges can alert the pilot of a significant problem or deficiency with the spark plugs of the craft. Generally, the magneto wears equivalent to the rate of the point faces. The system was designed this way so that the pilot can monitor the wear of the components and ensures that all aspects of the plane are functioning on the same timing structure. If there is a fluctuation in the RPM sensor, this could mean that there is significant wear to the components that could result in equipment failure. The pilot can also tell if the cam follower has adequate lubrication by monitoring the RPM sensor. They will have warning before the aircraft engine develops delayed timing, or if the fuel is not being burned properly. When to Replace the RPM Sensor If you notice any deviation in the RPM reading, you should first have all of the components connected to it checked. Some of them may need to be replaced. If you have replaced all of the parts that are associated with the RPM Sensor, and it is still providing a fluctuating reading, you should probably replace the RPM Sensor. Replacing the Aircraft Sensor Systems is a lot easier than you may think. All you have to do is remove the vent plug from the magneto plug. Insert the right aircraft flight instruments (which will vary depending on your specific aircraft). Feed the wiring bundle toward the firewall, but do not detach it. Make sure you have enough slack in the wiring bundle and plug the connector according to the package instructions. |
