Introduction
The Endress+Hauser Liquicap FTI51 is a robust capacitive rod probe designed for point level detection in highly viscous, build-up forming liquids. Featuring active build-up compensation, it delivers reliable level, interface, and foam detection in demanding industrial and hygienic applications, with flexible communication and comprehensive global approvals.
Key advantages
1. Active Build-Up Compensation: Eliminates false triggers from sticky, high-viscosity media deposits, ensuring reliable point level switching without routine maintenance.
2. Multi-Function Detection: Detects liquid level, liquid-liquid interfaces, and foam in conductive media, enabling dual-point pump control with just one process connection.
3. Extreme Process Resilience: Withstands temperatures from -80°C to +200°C and pressures up to 100 bar, suitable for harsh industrial environments.
4. Fast, Calibration-Free Commissioning: One-button calibration allows quick setup; no recalibration needed after electronics replacement, reducing downtime.
5. Universal Compliance & Safety: SIL and WHG overfill prevention certified, with ATEX, marine, and hygienic approvals for use across global industries.
