Delta Speed Sensor DRS1000
The Delta Speed Sensor is an inexpensive, noncontact Doppler radar speed sensor suitable for a wide variety of applications. Small and lightweight, it requires only asmall DC power source, making it ideal for situations requiring portability or remote sensing. The Delta Speed Sensor may be placed on a moving vehicle or mounted stationary. It can measure surfacespeeds, such as vehicle ground speed or it can be used to measure the speed of a moving target. The target can be anything from a wire passing under the sensor to a vehicle a thousand feet away. The outputof the sensor is a pulse with frequency proportional to measured speed. The aggregate number of pulses may also be used to determine surface length or distance traveled. The sensor can interfacedirectly with many different types of off-the-shelf hardware, such as digital tachometers, or can be integrated into electronic control or data acquisition systems.

Features
- Non-contact speedmeasurement - Inexpensive - Digital pulse output automatically enabled according to signal strength or target presence - Small, lightweight - Low power requirement - Weather resistant

Typical Applications- Vehicle ground speed measurement - Amusement park ride testing - Conveyor belt operations - Motion sensing - Speed control - Traffic monitoring - Length or Distance Measurements
