Endress+Hauser FTM20 Series Vibration Level Switch Level Switch, Threaded Mount, IECEx, ATEX-Rated, Housing Polyester

This vibration level switch detects material presence using oscillatory sensing and is intended for industrial process control. It operates across a wide ambient temperature range and connects via a threaded mounting for straightforward installation. The unit is built for use where electrical switching at common AC and DC levels is required and is suitable for environments that demand hazardous-area certification.

• Withstands up to 70°C for high-temperature process compatibility
• Operates down to -40°C for low-temperature installations
• Rated to 25 bar to tolerate pressurised vessels
• Accepts up to 253V AC for standard mains integration
• EPDM sealing prevents ingress and maintains process integrity
• Polyester enclosure resists chemical exposure in plant settings

• Suitable for monitoring bulk solids in storage silos
• Ideal for level detection in pressurised tanks
• Used with mixers where vibration-based sensing is required
• Can be used for pump dry-run protection in pipe systems
• Suitable for use in hazardous atmospheres requiring certified equipment

A threaded mount is provided to secure the sensor into standard process flanges or ports for a sealed mechanical connection.

The device carries IECEx and ATEX hazardous-area certification enabling deployment in classified zones.

Do not exceed 253V AC for alternating supply or 45V DC for direct supply to avoid electrical overstress.

The housing is polyester for external protection while an EPDM gasket provides the process seal at the connection interface.
