Radar sensor for accurate ground speed measurement
ifm offers a lightweight and compact, yet robust and precise radar sensor for ground speed measurement that is user-friendly and easy to configure for most applications.
Using the Doppler principle, the R1D201 sensor detects the speed of the vehicle and outputs the true process value of speed automatically via the CAN interface.
Benefits
- Non-contact speed measurement with minimal modificaiton of the currecnt mechanical structure required. No physical contact with the target makes it durable and low maintenance.
- High accuracy in all weather conditions. Reliably operates in rain, fog, snow, or dust where optical systems often fail.
- All-terrain compatibility, including dirt, gravel, pavement, etc. Not affected by tire wire or slippage as wheel-based sensors are.
- Compact and lightweight footprint allows installation in minutes.
- Real-time speed monitoring enables operators to make changes as needed.
- Speed is detected in both forward and backward directions.
