Signal conditioner
DC, 0-12 VDC, 0 - 999.9 gain | 126 Meggitt Sensing Systems - Measurement Group

The Endevco® model 126 is a low-cost, microprocessor controlled, three-channel DC differential voltage amplifier and signal conditioner. This model is designed with flexible setup and a wide bandwidth to 200 kHz (-3 dB corner), allowing it to be used with Endevco® bridge-type or differential output accelerometers and pressure transducers, or other industry models, across a variety of general purpose testing applications.

The model 126 incorporates variable gain adjustment, shunt calibration capability, as well as automatic zero adjustment capability for elimination of inherent DC offset voltage. The unit also features three independent operating channels with individually programmable excitation voltage level settings from 0-12 VDC; differential output and gain adjustment range from 0 to 999.9; an independent filter selectable function; and BNC output connectors, for easy hookup to readout and recording instruments. In addition, remote sense leads are provided to eliminate errors caused by driving long cable lengths.

Common applications for a high amplitude measurement system which includes the model 126 DC sensor vibration amplifier and signal conditioner, along with appropriate sensors, include drop testing; consumer electronic products testing; metal-to-metal impacts; penetration tests, structural blast loading; weapons data recorder testing; automotive crash test; and impact testing.
