The Dytran series 7700 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 various g ranges, the Dytran series 7700 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 DC 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 4-pin M4.5 x 0.35 radial connector and 10-32 stud mounting capabilities.

The Dytran series 7700 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.
