Meggitt Sensing Systems has announced the global introduction of the Endevco model 2228C, a rugged low-mass triaxial piezoelectric accelerometer suitable for general vibration testing requirements in research and development, metrology, lighting systems, wireless equipment, space shuttle and solid rocket booster electronics assemblies, helicopter engines, combustion turbines and vacuum pump applications. With a sensitivity of 2.8pC/g, the device provides high-reliability vibration measurements on three orthogonal axes with 10-32 receptacles to allow data collection from three separate output connections. These connections also offer a visual reference for the orthogonal axes being measured. With a package weighing 15g, the device effectively minimises mass loading on small structures and objects. Units operate over -55 to +177˚C, with mounting via two-hole screw or adhesive. The self-generating device requires no external power source for operation. Signal ground is isolated from the mounting surface of the unit. Low-noise, flexible coaxial cables are supplied for error-free operation. Also available with the device are the models 133 three-channel piezoelectric signal conditioner; the 2771C remote charge converter; the 2775B signal conditioner; the 6634C vibration amplifier; or the 4990A multi-channel signal conditioner.
