Endress+Hauser FTC260 Series Capacitance Point Level Switch Level Switch, Threaded Mount, ATEX-Rated, Housing Polyester

Endress+Hauser FTC260 Series Level Switch, 70°C Maximum Operating Temperature, 25 Bar Maximum Pressure - FTC260-AA4D1

This level switch is a capacitance-based point detector designed to monitor liquid levels in industrial settings. It operates across a wide ambient temperature span and is suitable for threaded installation where reliable, single-point detection is required. The device is built for environments that demand hazardous-area certification and supports common electrical interfaces for integration into control systems.

Features and Benefits:

• Operates between -40°C and 70°C for wide thermal range use
  Withstands up to 25 bar pressure for pressurised vessels
  Accepts up to 253V AC for direct AC supply compatibility
  Low energy draw of 30 mA to minimise load on circuits
  Tolerates up to 45V DC for low-voltage DC signal applications
  Polyester enclosure offers chemical-resistant external protection

Applications

• Suitable for level detection in pressurised tanks up to 25 bar pressure vessels
  Ideal for integration into hazardous-area installations requiring ATEX approval
  Used with control panels needing threaded sensor mounting
  Can be used for monitoring conductive and non-conductive liquids in process lines
  Suitable for systems operating from standard AC mains supplies

What mounting method does it use?

The unit fits via a threaded mount for straightforward panel or vessel thread installation.

Which certification allows use in potentially explosive atmospheres?

It carries ATEX hazardous-area certification permitting deployment where explosion risk assessments require such approval.

What material is the external casing made from?

The housing is manufactured from polyester to provide robust environmental resistance.

What electrical ratings should I consider for system design?

Design for a maximum AC voltage of 253V and a DC limit of 45 V, with a maximum current draw of 30 mA.

Can it be used in low-temperature applications?

Yes, it functions down to -40°C, enabling use in cold environments.
