FMCW Radar Level Transmitter

The FMCW radar level transmitter is a non-contact measuring device that is suitable for applications in high temperature, high pressure and corrosive environments. It is easy to install and requires no maintenance, especially in environments requiring high accuracy.

Main Features:

• Non-contact measurement
• Measurement of corrosive substances, toxic liquids, hydrocarbons, and slurries
• Unaffected by specific gravity, pressure, temperature, viscosity, or foam
• 5-digit LCD display
• Indicates the signal waveform inside the silo
• Selection of various measurement units (m, cm, mm, inch, Ft, %, mA)
• Distance and actual level measurement
• Language selection: Traditional Chinese, Simplified Chinese, English
• Output: 4-20 mA / 4-wire / 2-wire
• Modbus RS-485 for increased isolation and ease of remote control
• CE standards for isolation (EFT 2000V, Class B or better)
• Suitable for medium-range signal
• Isolated circuit design

Applications:

• Chemical industry
• Petrochemical industry
• Pharmaceutical industry
• Food industry
