Dual Axis Intelligent Accelerometer RD300

The RD300 combines Lamerholm Electronics advanced low cost piezo electric accelerometer technology with sophisticated electronics and software to offer an advanced intelligent accelerometer for vehicle damage monitoring.

Key Features

  • Very low cost
  • Two built in accelerometers
  • Built in temperature sensor and compensation
  • Serial digital output
  • Built in processor with damage detection algorithms
  • Low power consumption
  • Single 5V supply
  • Non volatile memory for custom mapping

Features

The RD300 has been designed as a very low cost disposable sensor to be fitted to fleet vehicles to monitor them for possible collision damage.

Whilst the primary target market is for hire fleets the device is also useful for large operator owned vehicle fleets where collision monitoring can make a significant contribution to operating cost reductions.

A pair of high performance piezo electric accelerometers monitor vehicle accelerations and vibrations in the horizontal plane. A micro processor analyses the signals from the sensors and continuously evaluates the probability of a collision having occurred.

When this probability exceeds a certain preset level the RD300 transmits a message on its serial data output describing the type and severity of the event.
