Endress+Hauser FTM20-GN45A in Stock: Robust Soliphant Vibration Level Switch

For industrial operations handling fine-grained or coarse-grained bulk solids, reliable point level detection is critical for safety and efficiency. The Endress+Hauser FTM20-GN45A is a high-performance vibration rod level switch from the renowned Soliphant® series, designed to deliver maintenance-free operation in silos, hoppers, and bins. This model is currently in stock and available for immediate shipment, ensuring you can minimize downtime and optimize your inventory management without delay .

What is the FTM20-GN45A?

The FTM20-GN45A is a compact point level switch that utilizes the tuning fork principle to detect the presence of solids. Unlike mechanical paddles or capacitive systems, this robust device is unaffected by material flow, air turbulence, or external vibration. It is engineered specifically for non-fluidized bulk solids, including plastic granules, cereals, cement, sand, and building materials .

Key Technical Specifications

Understanding the technical parameters is essential for ensuring compatibility with your application. The FTM20-GN45A offers a robust build and versatile electrical integration:

Measuring Principle: Vibronic (Vibration Solids) 

Application: Point level detection for fine-grained and coarse-grained bulk solids.

Process Connection: NPT 1-1/2" thread, constructed from 316L stainless steel. This ensures high corrosion resistance and durability, even with abrasive building materials .

Sensor Length: 225 mm (approx. 9 inches) .

Medium Properties:

Grain Size: ≤ 25 mm (0.98 in) .

Min. Density: ≥ 200 g/l .

Process Temperature: -40°C to +150°C (-40°F to +302°F) .

Process Pressure: -1 to +40 bar (-14.5 to +580 psi) .

Electronics & Output: Equipped with a DPDT relay (FEM24 type). This allows operation across a wide voltage range of 19-253 VAC / 55 VDC, making it compatible with global control systems .

Housing & Protection: Features an aluminum housing (Type 5F18) with an ingress protection rating of IP66/67 NEMA 4X. This rugged enclosure protects the internal electronics from dust, high-pressure water, and corrosive environments .

Approvals: Suitable for use in hazardous areas with dust ignition protection approvals (e.g., GIECEx t IIIC Da/Db), ensuring safety in dusty environments .

Advantages: Why Choose the Soliphant FTM20?

The Soliphant FTM20 series offers distinct operational advantages that reduce total cost of ownership and improve reliability compared to traditional mechanical switches.

1. True "Plug and Play" Operation

One of the standout features of the FTM20-GN45A is that it requires no calibration . Technicians can install the unit and put it into service immediately. This eliminates the complex setup time associated with capacitance or ultrasonic sensors, reducing commissioning costs and human error .

2. Maintenance-Free Design

Because the tuning fork has no mechanically moving parts, there is nothing to wear out, jam, or break . This design ensures a long operating life, significantly reducing maintenance interventions compared to rotary paddle switches, which are prone to mechanical failure.

3. Insensitive to Material Build-Up

In applications dealing with sticky or moist solids, material buildup on the sensor can cause false readings in many devices. The FTM20 is designed to be insensitive to buildup; the vibration frequency is powerful enough to shed deposits, ensuring that the switch only detects the actual level of the medium .

4. Universal Applicability

The measuring principle is unaffected by the electrical properties of the material. Whether you are measuring conductive substances (like wet sand) or non-conductive materials (like plastic pellets), the FTM20 provides reliable, repeatable results .

5. Abrasion Resistance

The 316L stainless steel wetted parts offer high resistance to abrasion. This makes the FTM20-GN45A ideal for demanding applications such as animal feed, cement, and construction materials that would quickly wear down lesser sensors .

Immediate Availability

Unlike long lead-time items that can stall projects, the Endress+Hauser FTM20-GN45A is in stock and ready to ship . This immediate availability ensures you can maintain continuous production or quickly respond to critical equipment failures.

Conclusion

The Endress+Hauser FTM20-GN45A represents the pinnacle of reliable, low-maintenance level detection for bulk solids. With its robust 316L construction, simple installation, and high-temperature/pressure ratings, it is the ideal solution for optimizing your industrial process.
