Meggitt Sensing Systems, a Meggitt group division, has recently introduced the Endevco® model 2775B, a high-reliability benchtop signal conditioner with fixed amplitude output signal and real-time front panel level meter, for use within environmental test laboratory, aerospace test cells, ESS, calibration systems and general vibration laboratory testing applications.

The Endevco® model 2775B is designed to accept inputs from ISOTRON® (IEPE-type) transducers, piezoelectric transducers, and remote charge converters (RCCs), with a full scale input range from 0.01 to 100,000 engineering units (EU's) and a wide sensor sensitivity input range of 0.01 to 10,000 mV/EC and RC/EU, with a gain range of 0 to 10,000 and a frequency response bandwidth of 120 kHz (-3 dB corner). Units offer AC, DC and servo outputs and operate from 90-240 VAC input power, with selectable ground isolation for cleaner data collection. With capability to install up to six units in an optional 19-inch rack accessory (model 4948A), the flexible setup of the model 2775B is accomplished either manually via the unit's front panel, or via the unit's integral RS232 interface using the supplied optional application software (model 35933A). An additional filter card (model 35771) or filter with single/double integration (model 35818) is also possible.
