The Dytran model 7604A3 is a high precision variable capacitance (VC) accelerometer, designed to be used as a drop-in replacement for piezoresistive units in new or existing zero-to-medium frequency instrumentation applications.

Available with a 25g range, the Dytran model 7604A3 incorporates a MEMS capacitive sensing element and an advanced ASIC to simulate piezoresistive bridge operation, as well as an integrated VC accelerometer chip with high drive, low impedance buffering. Units respond to both DC and AC acceleration. On-board regulation minimizes supply voltage variation effects, making them relatively insensitive to temperature changes and thermal gradients. Sensors are hermetically sealed for reliable operation in high humidity and dirty environments, and feature a custom integrated circuit amplifier and differential output stages, with a flying leads integral cable.

The Dytran model 7604A3 accelerometer uses the same power supply as piezoresistive and strain gage sensors, allowing them to operate as stand-alone differential output accelerometers or in place of piezoresistive bridge-type accelerometers. This unit uses an integral cable with an environmental boot and a laser welded hermetically sealed housing for reliable operation in high humidity and dirty environments.
