The Vibration Division of PCB Piezotronics, Inc., (PCB) has expanded its line of Health & Usage Monitoring Systems (HUMS) products, to include new ICP, charge output and high temperature sensors. HUMS products are designed for in-flight monitoring and predictive maintenance of critical flight systems on helicopters and some fixed wing aircraft.

PCB HUMS sensors feature a robust design, are available in either ICP or charge output designs, with top or side exit electrical connectors, and in a variety of hermetically sealed physical configurations. High temperature versions operate up to +900 ºF (+482 ºC); with a + 500 g pk measurement range; and in frequencies of up to 15k Hz. Also available is the new Model 495B10 differential charge converter, operating from aircraft power, will condition the signal of a charge output accelerometer, enabling it to be used by standard data acquisition equipment.
