The SICK LFV300 Series Level Sensor precisely detects predefined liquid levels in systems to the millimeter – even under difficult operating conditions. The switches can emit a signal to prevent overfilling, a switching signal for refilling, or a dry-run signal for pump protection. The LFV300 works independently of the liquid and is wear-free and maintenance-free. A wide selection of flange, threads, and hygienic connections together with a modular device concept enable customer-specific solutions. The device is suitable for hygienic applications and can be cleaned using SIP/CIP. There are also variants for use in explosive atmospheres, to prevent overfilling in compliance with WHG, and with marine certification (GL). Besides the rugged LFV310 standard device, there are LFV330 tube-extended variants for reliable vertical mounting to bridge sensing ranges up to 6 m.
