Radarowy przetwornik poziomu JFR3 FMCW

The JFR3 FMCW radar level transmitter is a non-contact measurement device suitable for measuring liquid levels in most tanks. It is easy to install, easy to maintain, and can be used in corrosive applications. Its high precision and stability make it widely used in liquid level detection and industrial process control.

FMCW radar (JFR) uses a high-frequency scanning method (in the GHz range); electromagnetic waves are transmitted from an antenna to the target being measured and then reflected back to the receiver over time. During this time, a frequency difference appears, which can be further calculated to obtain the distance from the transmitter tip to the target being measured. The FineTek FMCW radar uses K-band frequency scanning, with a measurement bandwidth of approximately 1 GHz. This frequency difference is processed by a fast Fourier transform (FFT), which allows for accurate differentiation of the main signal from background noise or echoes. The use of a phase-locked loop (PLL) circuit ensures high measurement accuracy and reliability.

Main features:

• Non-contact measurement
• Ability to measure corrosive and toxic liquids, hydrocarbons, and slurries
• The measurement is not affected by specific gravity, temperature, viscosity, or foam
• Echo wave display - allows for precise adjustment and setting of parameters
• Scanning of the measurement range, editing and removing background noise, save function
• Ability to display distance, material level, percentage, and 4-20mA current
• Low power consumption: max. 480 mW at 24 V DC (2-wire)
• Calibration and parameterization possible using FAS software on PC

Applications:

• With its versatile on-site level meter display, it can be used for distance measurement, liquid level measurement, stock level indication, or pump control.
• Liquid level monitoring in raw water, recycled water, or wastewater in various applications such as storage tanks, rivers, canals, swimming pools, etc.
• Liquid level measurement in process tanks containing media such as water, grease, resin, paint, heavy oil, beverages, etc.
