E+H tuning fork level gauge FTL31-AA4M2AAWBJ limit switch instead of FTL20-0025

Tuning fork limit switch FTL31

Limit detection switches in a compact hygienic design and stainless steel housing

The Liquiphant FTL31 liquid limit switch is suitable for all industrial measurements, mainly in the machinery industry. Liquiphant can be used for cleaning, filtration systems as well as spill protection in cooling and lubricating containers and dry running protection of pumps.
compact:
- Smallest size tuning fork sensor on the market
Safety:
- Continuous self-monitoring
- Reliable switching action, not affected by medium properties
Simple:
- No calibration or adjustment required
- Plug and play

Advantage
Designed to meet the highest quality and environmental sustainability requirements. The self-monitoring Liquiphant switches safely even in the event of a power failure.

Unaffected by changes in medium properties, providing precise switching points

Plug and play sensors can be used practically without adjustment, even in the case of changing media. Measurements unaffected by conductivity, sticking, disturbance, flow or air bubbles

No calibration required, no specific knowledge or tools (eg: software) required

Rugged stainless steel (316L) for maximum durability - no mechanically moving parts, maintenance free

Modular design offers different process temperatures and the widest variety of process connections and accessories on the market to meet every application requirement

No mechanical moving parts, maintenance free


Application field
The FTL31 is a reliable limit detection switch in a compact design with a stainless steel housing; suitable for general industrial applications in all industries, such as OEM equipment with limited installation space.
