Description
Introduction
The Endress+Hauser Liquiphant FTL43 is a compact, hygienic tuning fork level switch purpose-built for liquid applications in food & beverage, life sciences, and aseptic processes. It delivers reliable, maintenance-free high/low level detection, overfill protection, and pump dry-run prevention—even in narrow skids, pipelines, and tight process tanks. With plug-and-play functionality, certified hygienic design, and optional IO-Link/Bluetooth communication, it combines ease of use with continuous diagnostics via Heartbeat Technology, making it ideal for both standard and demanding sanitary environments.
Key advantages
- Sanitary & Versatile Hygienic Design：Electro-polished 316L wetted parts, certified to 3-A, EHEDG, and global food contact standards (FDA, EC 1935/2004), supporting Tri-Clamp, Ingold, and other industry-standard hygienic connections.
- Wide Operating Range with High Pressure/Temp Resistance：Reliable performance from -40 °C to +150 °C process temperature and vacuum to 64 bar (928 psi) overpressure, with optional density compatibility down to 0.4 g/cm³.
- Smart Diagnostics & Safety Compliance：CRC checksum algorithm ensures parameter integrity, while Heartbeat Technology enables on-demand verification without process interruption, supporting WHG overfill protection compliance.
- Flexible Communication & Easy Integration：IO-Link, HART, and Bluetooth connectivity enable remote configuration, monitoring, and maintenance, paired with one-button operation and plug-and-play commissioning for fast setup.
- Compact & Adaptable Form Factor：Optional pipe extensions up to 1.5m (5 ft) fit narrow skids and modules, while the compact hygiene housing minimizes installation footprint without compromising performance.
