Description

The Renke RS-RAD-N01-1-EX employs Frequency-Modulated Continuous Wave (FMCW) radar technology operating in the 76–81 GHz millimeter-wave band. This advanced principle allows for highly accurate distance measurement by comparing the frequency shift between transmitted and reflected signals, ensuring stability unaffected by temperature, pressure, or vapor presence in the measurement path.

Its integrated CMOS RF chip and compact lens design produce a narrow 6° beam angle, minimizing interference from tank walls, agitators, or other obstructions. The sensor is engineered for continuous, maintenance-free operation in demanding applications, from water resource management to industrial process control, thanks to its IP67 protection against dust and water ingress.

Key Features

  • Advanced 76–81 GHz FMCW radar ensures high measurement precision and stability.
  • Exceptional ±1 mm accuracy across the entire 0.1 m to 65 m sensing range.
  • Narrow 6° beam angle reduces false echoes and environmental interference.
  • IP67-rated enclosure provides robust protection against dust and temporary water immersion.
  • Low 0.2 W power consumption enables energy-efficient, continuous monitoring.
  • Wide operating temperature range from -40°C to +80°C for extreme environment suitability.
  • RS485 digital output facilitates reliable long-distance communication and easy integration into SCADA, PLC, or data logger systems.
  • Compact and durable design simplifies installation and ensures long-term reliability.

Applications

  • Continuous level monitoring in industrial storage tanks for water, chemicals, or fuels.
  • Water resource management in rivers, reservoirs, lakes, and irrigation channels.
  • Level measurement in sewage treatment plants and wastewater holding tanks.
  • Process level control in food & beverage, pharmaceutical, and petrochemical industries.
  • Flood warning and rainfall monitoring stations for environmental surveillance.

Frequently Asked Questions

What is the communication protocol and how do I wire the RS485 interface?

The sensor uses a standard RS485 digital communication interface, typically operating on a Modbus RTU protocol. You will need a 2-wire connection (A and B data lines) plus power and ground from the 10-30V DC supply. Consult the manufacturer's datasheet for the specific register map and wiring diagram to integrate it with your PLC, data logger, or SCADA system.

What is the minimum and maximum measurable distance for this radar sensor?

The Renke RS-RAD-N01-1-EX has a non-contact measurement range from 0.1 meters (100 mm) up to 65 meters. The ±1 mm accuracy specification is maintained across this entire range, making it suitable for both close-proximity and long-distance level monitoring applications.

Is this sensor suitable for outdoor use and harsh environments?

Yes. The sensor features an IP67 ingress protection rating, meaning it is dust-tight and can withstand temporary immersion in water up to 1 meter for 30 minutes. Combined with its wide operating temperature range of -40°C to +80°C, it is designed for reliable performance in outdoor and harsh industrial environments.

How narrow is the radar beam, and why is that important?

The sensor has a very narrow 6° beam angle. This focused beam is crucial for minimizing interference from tank walls, internal structures (like ladders or agitators), or foam on the liquid surface. It ensures that the radar signal is primarily reflected from the target material, leading to more stable and accurate measurements.
