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

This level switch is a vibration-operated sensor designed for point detection in industrial fluid and bulk material systems. It is intended for threaded installation and functions across a broad temperature span, providing discrete level indication in processes where robust hazardous-area performance is required.

• Polyester housing resists environmental exposure while remaining lightweight
• EPDM gasket prevents ingress and maintains sealing integrity
• Operates reliably between -40°C and 70°C for varied process conditions
• Withstands system pressures up to 25 bar for pressurised vessels
• Compatible with up to 253V ac and 45V DC for flexible electrical integration
• Certified for IECEx and ATEX environments to permit use in explosive atmospheres

• Suitable for point level detection in storage tanks and hoppers
• Ideal for use on pressurised process vessels requiring 25 bar capability
• Used with hazardous-area installations where IECEx and ATEX certification is needed
• Can be used for liquid and interface sensing in temperature-varying processes

It is designed for a threaded mount which enables secure attachment to standard process ports and fittings.

The gasket material is EPDM which provides resistance to many aqueous solutions and helps maintain a reliable seal under typical process conditions.

The device accepts alternating supply up to 253V ac and direct supply up to 45V DC, allowing integration with common control systems.

The outer shell is made from polyester, offering a durable non-metallic option where metal enclosures are not desirable.
