Self-diagnosing Sensors An Ace For Aircraft Safety

Honeywell’s Integral Health Monitoring (IHM) series self-diagnosing sensors are designed to improve the performance of aircraft systems and reduce maintenance costs associated with false readings. The sensors can detect when damage has occurred or performance impacted. The patented proximity sensors can be designed into a range of aircraft systems such as thrust reverser actuation systems, flight controls, aircraft doors, cargo loading systems, evacuation slide locks and landing gear.

 

The proximity sensors are configurable, non-contact devices designed to sense the presence or absence of a target in harsh-duty aircraft applications such as determining when a thrust reverser is not fully closed. The sensors can detect most internal failures and display a fault output to a pilot or maintenance worker in order to help reduce aircraft downtime and maintenance costs.

 

For example, proximity sensors in aircraft landing gear systems provide a pilot with a fault alert on landing approach to warn if the landing gear is not completely deployed. With Honeywell's health-monitoring feature, the IHM proximity sensors can indicate if the error message was caused by the sensor itself rather than an issue with the landing gear.

 

Honeywell also introduced Linear Variable Differential Transformers (LVDT), which are used in engine mechanisms, pilot controls and nose-wheel steering applications, and provide next-generation aircraft with continuous position monitoring and are designed for use in harsh environments.

 

For both new sensors, Honeywell offers design engineering support and a standard design platform in which the engineering work is performed upfront to provide an off-the-shelf solution to speed up customer design cycle times. For more information, checkout an appnote.
