Description

The FMR20B level transmitter utilizes 80 GHz frequency-modulated continuous wave (FMCW) radar technology to deliver precise, continuous level measurement without physical contact with the medium. This principle ensures reliable performance even in applications with foam, vapor, or dust. The integrated signal processing provides stable readings with high immunity to process noise and interference.

Engineered for harsh industrial environments, the transmitter operates within a wide temperature range from –40°C to +80°C and withstands process pressures up to 3 bar. Its PBT/PC housing offers excellent chemical resistance and durability. The device supports modern industrial communication via its 4-20mA/HART output, while optional Bluetooth enables safe, wireless access for configuration and diagnostics in hard-to-reach or hazardous areas.

Key Features

  • 80 GHz FMCW radar sensor for superior signal focus and measurement stability.
  • High-value build with PBT/PC housing for corrosion resistance and long-term reliability.
  • Integrated HART protocol allows for digital parameterization and diagnostics over the standard 4-20mA loop.
  • Bluetooth wireless interface provides secure, encrypted remote access for commissioning and maintenance.
  • Wide operating temperature range (–40°C to +80°C) suitable for extreme outdoor and indoor conditions.
  • Tool-free installation and guided commissioning interface reduce setup time and operational costs.
  • On-site touch display and LED status indicator enable quick local operation and diagnostics.

Applications

  • Continuous level monitoring of water, chemicals, and process liquids in storage tanks and reactors.
  • Inventory management of bulk solids like grains, plastics, and powders in silos and hoppers.
  • Process control and overfill prevention in pharmaceutical, food & beverage, and chemical processing plants.
  • Level measurement in wastewater treatment facilities, including clarifiers and digesters.
  • Remote tank farm monitoring integrated with SCADA systems via HART communication.

Frequently Asked Questions

What is the power supply requirement for the FMR20B transmitter?

The FMR20B operates on a standard two-wire 4-20mA loop, requiring a DC supply voltage between 12 and 30 volts. This powers both the sensor electronics and provides the current loop for the analog output signal, making it compatible with most industrial power supplies and PLC analog input modules.

How do I communicate with this transmitter for configuration?

Configuration can be performed via the integrated HART protocol using a HART communicator or modem connected in series with the 4-20mA loop. Alternatively, the optional Bluetooth feature allows for secure, wireless configuration and diagnostics using a compatible mobile device and the manufacturer's app, which is ideal for hazardous or difficult-to-access installations.

What is the purpose of the flooding protection tube?

The flooding protection tube (also known as a stilling well) is installed around the antenna. It protects the radar antenna from direct contact with the medium, minimizes signal disturbance from surface turbulence or agitators, and ensures a stable reflection surface for highly accurate and repeatable level measurements, especially in agitated liquids.

Can this sensor measure both liquids and solids?

Yes, the 80 GHz FMCW radar technology is suitable for measuring the level of both liquids and bulk solids. Its high frequency provides a focused beam, allowing for reliable measurement even on low-dielectric materials or in applications with obstructions, dust, or foam. The device parameters can be optimized for the specific medium during commissioning.
