Design of the Endevco® model 2220E features Meggitt’s own proprietary piezoelectric crystal sensing element in annular shear mode, a configuration which exhibits excellent output sensitivity stability over time. The lightweight (3.1 gm) and compact size of the model 2220E minimizes mass loading effects. 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 utilizes a centrally located thru bolt, allowing for 360° cable orientation. It may also be adhesive mounted. As a self-generating device, the Endevco® model 2220E requires no external power source for operation. Units are also hermetically sealed, making them ideal for use in extreme environments such as aircraft engine ground vibration testing; automotive and aerospace component durability testing; auxiliary power unit (APU) monitoring; helicopter and rotorcraft health and usage monitoring systems (HUMS) testing; in-laboratory shaker table component vibration testing; and large manufacturing machinery and equipment vibration monitoring.
A specially designed low-noise coaxial cable, the Endevco® model 3053V-120, is also supplied for error-free operation. Additional recommended accessories, sold separately, include the model 2771C-XX in-line remote charge converter; the model 133 three-channel signal conditioner; the model 2775B signal conditioner; or the model 4990a (Oasis) multi-rack mounted modular signal conditioning system. In addition, the model 2220E is accompanied by a comprehensive five-year product warranty, with quantities available for immediate shipment under Meggitt’s Endevco® Guaranteed In StockTM program. It is also available at specially discounted rates as part of the -R replacement sensors program. For more information, visit www.meggittsensingsystems.com.
