The Delta DRS1000 Non-contact Speed Sensor is a Doppler radar sensor suitable for a wide variety of speed measurement applications.
The sensor may be placed on a moving vehicle to measure vehicle ground speed. It may also be mounted in a stationary position to measure the speed of a moving object which can be anything from a thin wire passing under the sensor to a vehicle 300 meters away. The output of the sensor is a pulse with a frequency proportional to the measured speed. The cumulative number of pulses may be used to determine distance traveled or the length of a moving surface.
The speed sensor may be used with many different types of off-the-shelf hardware such as timers, counters, or digital tachometers. It can also be integrated into electronic control or data acquisition systems.
