Health and usage monitoring systems for aircraft hoist systems are described herein. In some embodiments, a health and usage monitoring system comprises a capacitive load cell and a processing unit for communication with the capacitive load cell, the capacitive load cell comprising a load receiving surface and a capacitive assembly coupled to the load receiving surface, the capacitive assembly comprising parallel electrically conductive plates separated by a reversibly deformable spacer construction wherein the parallel plates comprise aligned apertures providing a passageway through the capacitive assembly for the hoist system cable.

Hoist health and usage monitoring system and components thereof

A method of detecting a combustion chemical in a region and setting an alarm based on concentration levels of the combustion chemical comprises the steps of: monitoring the region for a combustion chemical with a sensor having a measurable parameter which changes in value proportional to concentration levels of the monitored combustion chemical, the measurable parameter being ambient temperature dependent; generating an ambient temperature measurement of the sensor; reading the measurable parameter and ambient temperature measurement; processing the measurable parameter and ambient temperature measurement readings to generate a temperature compensated concentration level of the monitored combustion chemical; and setting an alarm based on the generated temperature compensated concentration level. A fire detector unit for implementing the foregoing described method is also disclosed.
