krohne Radar level transmitters / OPTIWAVE 6300 C

VF63400P10A0001010000100 - (Non-contact Radar (FMCW) Level Meter for Solids)

The Krohne Optiwave 6300 C uses 24 GHz FMCW radar to measure the distance to a material's surface, which is then converted to level, volume, or mass. It generates a continuously sweeping radar wave that reflects off the product, and the device measures the time-of-flight or the frequency difference of the reflected signal to calculate the distance. This non-contact method is ideal for dusty environments and challenging solid material measurements.

Working Principle

1. Radar Wave Transmission: The device emits a continuously sweeping microwave signal (FMCW - Frequency Modulated Continuous Wave) from its antenna.
2. Reflection: This radar wave travels to the material's surface in the tank or silo and reflects back to the antenna.
3. Signal Analysis: The device compares the frequency of the emitted wave with the frequency of the received, reflected wave.
4. Distance Calculation: The difference in frequency is directly proportional to the distance of the material's surface from the antenna.
5. Level Determination: The distance is then converted into a level measurement.
6. Output: The calculated level is transmitted to a control room via a standard 4-20mA signal.

Key Features

• Non-Contact Measurement: Ensures no physical contact with the measured material, reducing wear and tear and maintenance.
• 24 GHz FMCW Radar: Provides accurate and reliable measurements, especially for solids like powders and granules.
• Drop and Horn Antennas: Offers different antenna options suitable for various materials and process conditions, including polypropylene (PP) and PTFE drop antennas for dusty atmospheres.
• Dusty Applications: Designed for dusty conditions and hazardous area applications, making it suitable for challenging environments.
• SIL2 Compliant: Meets safety standards for use in Safety Instrumented Systems (SIS).
