Unmatched Advantages for Bulk Solids Detection

Why choose the Endress+Hauser FTM20-AA42A over other level measurement technologies? The benefits extend far beyond basic level detection.

1. "Plug and Play" Commissioning

One of the most significant advantages of the FTM20-AA42A is its simplicity. The device requires no calibration. It can be installed and put into operation immediately, saving valuable time and eliminating the need for specialized technicians during setup .

2. Insensitive to Material Build-Up

Traditional point level switches often fail due to material adhering to the sensing element. The tuning fork of the FTM20 is specifically designed to minimize build-up, and its electronics filter out false signals caused by product accumulation. This ensures reliable switching even with sticky or adhesive solids like palm fruits or wet sand .

3. Maintenance-Free Operation

With no mechanically moving parts such as seals or motors to wear out, the Soliphant T FTM20 eliminates the primary failure points found in paddle switches. This results in lower maintenance costs and higher uptime for your facility .

4. Immune to External Influences

Process conditions like high vibration, flowing material, or air turbulence can confuse other sensors. The FTM20-AA42A’s active frequency monitoring ensures that only the damping of the tuning fork (caused by the medium) triggers a switch, ignoring external noise and ensuring fail-safe operation .

5. Reusable Function Test

The device features a built-in test magnet function, allowing for easy and recurring function testing without opening the housing or interrupting the process. This facilitates simple proof testing during routine maintenance checks .

Typical Applications

The rugged design of the FTM20-AA42A makes it ideal for various industries:

Chemical: Monitoring plastic granules or powdered pigments.

Food & Beverage: Level detection in grain silos, flour bins, or sugar tanks.

Palm Oil Mills: Robust limit detection in digesters to optimize fruit processing .

Minerals Processing: Fly ash, cement, or sand level detection.
