Mini piezoelectric accelerometer for jet engine and helicopter vibration testing introduced by Meggitt
SAN JUAN CAPISTRANO, Calif., 23 April 2012. Meggitt Sensing Systems in San Juan Capistrano, Calif., is introducing the model 2220E miniature piezoelectric accelerometer for high-temperature vibration measurements in applications such as aircraft engine ground vibration testing, automotive and aerospace component durability testing, auxiliary power unit (APU) monitoring, and helicopter health and usage monitoring systems (HUMS) testing.
The 2220E operates in temperatures as hot as 260 degrees Celsius, weighs 3.1 grams, and has a compact size to keep loading effects to a minimum. The design Meggitt's proprietary piezoelectric crystal sensing element in annular shear mode for sensitivity stability over time.
Signal ground is connected to the outer case of the unit. When used with its supplied isolated mounting screw assembly, the accelerometer is electrically isolated from ground. The transducer uses a centrally located thru bolt, allowing for 360-degree cable orientation. It may also be adhesive mounted, and requires no external power source for operation.
Units are also hermetically sealed, and also can be used in applications such as in-laboratory shaker table component vibration testing and large manufacturing machinery and equipment vibration monitoring.
The sensor comes with a specially designed low-noise coaxial cable. For more information contact Meggitt Sensing Systems online at www.meggittsensingsystems.com.
