Compact Point Level Detection for Bulk Solids
The Soliphant FTM20 is designed for applications where the requirement is straightforward: detect whether a bulk material has reached a defined level.
Its vibronic measuring principle provides point-level switching for fine and coarse materials without the need for a continuous level transmitter.
Designed for Fine and Coarse Materials
The FTM20 is suitable for fine-grained and coarse-grained, non-fluidized bulk solids. This makes it applicable to a wide range of dry materials handled in storage and process equipment.
A Simple Solution for Everyday Level Monitoring
Compared with larger Soliphant configurations designed for extended measuring lengths or particularly demanding process conditions, the FTM20 focuses on a compact and straightforward installation.
Its 225 mm sensor length and threaded process connections make it well suited to typical silos, hoppers and vessels where a standard point-level switching arrangement is sufficient.
Built for Industrial Conditions
The FTM20 is specified for process temperatures from -40 to +150°C and process pressures from vacuum to 25 bar. The main wetted parts are made of 316L, providing a familiar material choice for industrial bulk-solid applications.
Suitable for Dust and Hazardous Areas
Depending on the selected configuration, international explosion-protection approvals are available. This allows the FTM20 to be used in installations where combustible dust or hazardous-area requirements need to be considered.

FAQ
What is the Endress+Hauser Soliphant FTM20?
The Soliphant FTM20 is a vibronic point level switch for bulk solids. It detects whether a dry material has reached a defined minimum or maximum level.
What materials can the FTM20 detect?
The FTM20 is designed for fine-grained and coarse-grained, non-fluidized bulk solids with a minimum medium density of 200 g/L.
Is the FTM20 a continuous level transmitter?
No. The FTM20 is a point level switch. It provides a switching signal when the bulk material reaches the defined detection point.
What are the temperature and pressure limits?
The specified process temperature is -40 to +150°C, while process pressure ranges from vacuum to 25 bar.
What is the sensor length?
The standard FTM20 sensor length is 225 mm.
What material is used for the sensor?
The main wetted parts are made from 316L stainless steel.
What process connections are available?
The FTM20 is available with threaded process connections, including R1", R1 1/2", 1 1/4" NPT and 1 1/2" NPT, depending on configuration.
What outputs are available?
Depending on the selected electronics, the FTM20 can be configured with a DPDT relay or DC-PNP output.
Can the FTM20 be used in hazardous areas?
Yes. Endress+Hauser lists international explosion-protection approvals including ATEX, FM, CSA, CSA C/US, IECEx, NEPSI and EAC, depending on configuration.
What is the difference between FTM20 and Solicap FTI55?
The FTM20 uses a vibronic measuring principle, while the FTI55 uses capacitance measurement. Both are point-level devices for bulk solids, but they use different sensing technologies and have different application characteristics.
