The L92 Series Vibrating Fork Point Level Switch is a heavy-duty stainless steel vibrating fork ideal for measuring the presence of solids and powders across a wide range of media and applications. When materials come into contact with the fork tines, the frequency of vibration falls relative to the natural resonance frequency in free air, sending an electronic signal detecting the presence of material. These durable, yet compact, devices come with a wide range of electrical connections, outputs, fittings, and a number of other selections to meet any end-user demands. The vibrating fork level switch is ideal in free flowing powders and granules, most commonly found in the agriculture and cement industries. They can be mounted on the top or side of tanks or grain elevators, and can operate in temperatures up to 392°F and pressures up to 215 PSIG.
