Six-DOF sensor

  • 06-Jul-2009 04:44 EDT

The DTS 6DX from Diversified Technical Systems incorporates three linear accelerometers and three angular rate sensors in a compact package of 28 x 16.5 mm (1.1 x 0.65 in), with a mass of 26 g (0.92 oz). The six channels of output provide the necessary data to calculate an acceleration vector and track its orientation in space with respect to time with post-processing calculations and plot the kinematic motion of a test piece in 3-D space. The unit is designed for high-speed impact environments and has a 6000 g shock rating. Built-in 16-pin micro circular connectors make the device durable and replacement of cables easy. The internal linear accelerometers are full bridge piezoresistive devices with a constant response, available in ranges from ±20 g to 6000 g.  The internal angular rate sensors come in ranges of ±300 to 50,000°/s and have a dc response. The sensor is suited for test and monitoring of vehicles such as crash impacts, rollover, suspension, ride and handling, as well as other applications including product testing of off-highway vehicles.
