SAN JUAN CAPISTRANO, Calif., 8 Dec. 2011. Meggitt Sensing Systems in San Juan Capistrano, Calif., is introducing the Endevco model 2793 16-channel power supply and signal conditioner for general purpose laboratory vibration testing, aerospace and automotive test cells or higher-channel count NVH testing applications. The device is designed to accept inputs from ISOTRON or other piezoelectric transducers and remote charge converters (RCC) within a high-impedance measurement system.
Each channel offers constant current excitation, either four milliamps or 10 milliamps for the transducer or RCC, with all outputs buffered for driving long cables, Meggitt officials say. The signal conditioning unit offers a frequency range of 1 Hz to 80 kHz, as well as LED status indicators that inform the user of short, open, or normal operating conditions.
Each channel provides gain (1 or 10) and current excitation (4 milliamps or 10 milliamps) settings, selectable by internal jumpers, as well as a "D" output connector for connection to a D/A board.
