Endress+Hauser FTM20-AG45A in Stock Reliable Vibrating Fork Point Level Switch

If you require a robust and maintenance-free solution for point level detection in fine-grained or coarse-grained bulk solids, the Endress+Hauser FTM20-AG45A is an industry-leading choice. Known for its part of the Soliphant series, this compact vibrating fork switch is engineered to deliver precise monitoring in silos, hoppers, and conveyors. Crucially, this model is currently in stock and available for immediate shipment, ensuring you can minimize downtime and maintain operational efficiency without the long lead times typically associated with industrial instrumentation .

Product Overview: What is the FTM20-AG45A?

The Endress+Hauser FTM20-AG45A is a point level limit switch designed specifically for non-fluidized bulk solids . It operates on the proven tuning fork measuring principle (vibration technology). The fork vibrates at its natural mechanical frequency. When the fork becomes covered by the material (e.g., granules, powder, or pellets), the vibration frequency changes, and the electronics detect this change to trigger a switching output .

This specific model variant, FTM20-AG45A, comes pre-configured with the FEM24 electronic insert. This robust configuration ensures compatibility with standard industrial control systems, featuring a DPDT relay output capable of handling high-voltage loads directly .

Advantages: Why Choose the Soliphant FTM20?

The enduring popularity of the Endress+Hauser FTM20 series stems from its combination of simplicity and rugged reliability.

1. "No-Calibration" Installation (Plug and Play)

One of the standout benefits of the FTM20-AG45A is that it requires no calibration. Unlike capacitive or conductive level switches that often need tuning to the specific material, the vibrating fork is ready to use straight out of the box. It simply works, detecting material regardless of its conductivity, moisture content, or dielectric constant .

2. Immune to Material Build-Up and Flow

In the world of bulk solids, material sticking to the sensor is a common cause of false alarms. The FTM20-AG45A is designed to be immune to build-up. As long as the fork itself is free, the device will not falsely trigger. Furthermore, its operating principle is unaffected by external vibration from machinery, turbulence during filling, or air currents .

3. True Maintenance-Free Operation

Because the FTM20 utilizes a piezoelectric drive with no mechanical moving parts to wear out, it offers a long, maintenance-free service life. There are no seals to wear, no motors to burn out, and the 316L fork is highly resistant to abrasion from constant material flow .

4. Robust and Environmentally Sealed

With a heavy-duty F18 Aluminium housing rated to IP66/67 and NEMA 4X, the device is fully protected against powerful water jets and temporary submersion. This makes it ideal for outdoor installations in any climate, from freezing cold to high heat .

5. Immediate Availability (In Stock)

While many suppliers quote lead times of 8-10 weeks for this equipment , we are pleased to confirm that the Endress+Hauser FTM20-AG45A is currently in stock and available for same-day or next-day dispatch. This immediate availability helps you avoid costly production halts and long project delays.

Applications
