FILL LEVEL SWITCH CONTROLLI DI LIVELLO Fili level switch LFV20 - Reliable Overfilling, Dry Run and Pump Protection Tutti i dati ed i contenuti di questa scheda sono di proprietà esclusiva di Riels Instruments The Riels LFV200 is an all-purpose limit switch with which pre-defìned fili levels can be detected in systems for liquids precisely to a millimeter Regardless of maximum fìll amounts in containers as full messages to prevent overfilling, empty messages to prevent dry running switching signal for refìlling or as idle message for pump protection, the LFV200 runs independently of the liquid and is wear-free and maintenance-free. Measurement principle The Riels LFV200 works according to the piezo-electric resonance principle. The sturdy oscillating fork made of stainless steel is oscillated piezoelectrically The actual resonance of the oscillating fork changes signifìcantly when it is immersed in a liquid. This frequency change is converted very reliably into a switching signal in integrated electronics applications. The LFV200 can be put into operation directly without any adjustment. The switching state is visible from the outside via a two-color LED. Area of use Because the LFV200 can measure all liquids reliably with a density greater than 0.7 g/m3, there are hardly any limits to its areas of use. Its high surface quality (Ra <0.8 pm) in connection with the available process connections makes optimum and unrestricted purity possible, even in applications with maximum hygiene requirements regardless of whether for permissible overfilling protection, full and empty messages, dry running or pump protection. Advantages - Operation startup without adjustment - Product-independent switching point - Very high degree of reproducibility - Wear and maintenance free - Minimum assembly dimensions - High degree of surface quality (Ra <0.8 pim) - Optimum for CIP and SIP cleaning Limit switch for full or empty messages Piezo-electric resonance switch Dimensional drawing 1: Process connection G 3/4” 2: Wrench size 32 Temperature range -40 ... 150 °C Electric connection MI2/IP 67 I: Process connection G 3/4” 2: Wrench size 32 Temperature range -40 ... 100 °C Electric connection MI2/IP 67 I: Process connection G 2: Wrench size 32 Temperature range -40 Electric connection Plug DIN43650/IP 65
