Meggitt Sensing Systems, a Meggitt group division, offers the Endevco Model 6222S Series, a high-temperature piezoelectric accelerometer family, designed for high-reliability vibration monitoring in helicopter health and usage monitoring systems (HUMS); ground and onboard aircraft engine monitoring; and ground-based gas turbine engine monitoring applications. They are available in three models, with sensitivities of 20, 50, and 100 pC/g and choice of three ruggedized connector styles. Models feature Meggitt’s proprietary Isoshear construction, which significantly reduces transient temperature and base strain outputs, while maintaining a high mounted resonance and continuous operation in temperatures of up to +260 C (+500 F) with long mean time before failure (MTBF). It comes with a standard ARINC three-point mounting configuration, three mounting bolts, and is designed with a rugged two-pin 7/16-27 UNS-2A threaded receptacle with an available three-pin option. As a self-generating device, the sensors require no external power for operation. The series provides a balanced differential output, allowing them to be used with any industry differential charge amplifier. This unit is designed to be compatible with the Endevco 6917B and 6917D Series of shielded, softline cable assemblies. For more information visit www.meggittsensingsystems.com.
