RLT1100 Series Radar Level Meter (FMCW 80GHz)

This device is an advanced FMCW radar level gauge that operates in the frequency range of 76 to 81 GHz and with an operating bandwidth of 5 GHz, it provides the ability to measure levels up to 120 meters. Its minimum blind zone is 8 cm and is available in two-wire and four-wire models. Using short millimeter waves, this level gauge provides accurate performance in challenging conditions such as dusty environments, high temperatures and sloping surfaces. Due to its advanced design, it can measure the level of liquids and solids in tanks, silos and industrial environments and maintains its efficiency even at working pressures up to 20 MPa and operating temperatures up to 1200 ° C (in the High Temp model). Applications involving liquids or bulk solids often use radar level measurement. It is suitable for level measurement in the oil and gas, chemical, food, pharmaceutical and corrosive environments or with acidic vapors. It is also ideal for inclined surfaces or conical tanks where high accuracy and reduced environmental interference are required. General benefits Level measurement up to 120 m for solids (0.6 to 120 m) and 30 m for liquids (0.08 to 30 m) regardless of the type of material (liquids or solids with a dielectric constant of at least 2). Precise level detection with a measurement accuracy of ±1 mm and a range resolution of ≈3 cm. Compact transmitter with dimensions Ø100 x 270 mm, 4-20 mA current output and programmable error outputs (e.g. 3.8 mA, 4 mA, 20 mA, 21 mA or Hold). Menu-guided operation with 128 x 64 dot graphic display and 4 push buttons (LDM) capable of displaying the echo curve, historical data and settings. Safe error handling with digital error codes (e.g. 0000 for normal operation, 0001 for no echo found). Flexible power supply with 15-28 VDC (two-wire) or 220 VAC (four-wire) and HART / RS485 / USB-to-serial communications for local or remote troubleshooting (including 4G and Bluetooth). Optional design with IP68 protection, Exd ia II C T6 explosion protection and threaded or flange mounting for use in areas with a risk of explosion and dust.
