7603B, High Precision Triaxial, MEMS Accelerometer

The Dytran 7603B is a high precision triaxial 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 2g range, this model incorporates MEMS capacitive sensing elements 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 9-pin 5/16-32 radial connector and 1/4-28 stud mounting capabilities.

This accelerometer utilizes the same power supply as piezoresistive and strain gage sensors, operating VDC power at ±3 to ±11V, allowing them to operate as stand-alone differential output accelerometers or in place of piezoresistive bridge-type accelerometers.
