Meggitt Sensing Systems, a Meggitt group division, has introduced the Endevco® model 2793, a 16-channel power supply and signal conditioner, designed to accept inputs from ISOTRON® or other piezoelectric transducers and remote charge converters (RCC) within a high-impedance measurement system.
Each channel of the Endevco® model 2793 offers constant current excitation, either 4 mA or 10 mA for the transducer or RCC, with all outputs buffered for driving long cables. The signal conditioning unit offers a relatively low per-channel cost and a wide frequency range of 1 Hz to 80 kHz. LED status indicators inform the user of short, open or normal operating conditions, ensuring greater test setup reliability. For added flexibility, each channel provides gain (1 or 10) and current excitation (4 mA or 10 mA) settings, selectable by internal jumpers. In addition, the model 2793 offers a “D” output connector for simple connection to a D/A board.
