Part # L90

The L90 Series Vibrating Fork Level Switch is a heavy-duty, stainless steel tuning fork for measuring liquids across a range of media and applications. When placed in liquids, the frequency of the vibrating fork falls relative to its natural resonance frequency in free air, sending an electronic signal detecting the presence of liquid. These durable, yet compact, devices come with a wide range of electrical connections, outputs, fittings, fork lengths and a number of other selections to meet any end-user demands. These devices are ideal in free-flowing liquids, and for flow detection in pipelines. They can be mounted on the top or side of tanks, and can operate in temperatures up to 392°F and pressures up to 215 PSIG.

Part # L91

The L91 Series Vibrating Rod Point Level Switch is a heavy-duty stainless steel vibrating rod ideal for measuring the presence of solids and powders across a wide range of media and applications. When materials come into contact with the measuring rod, 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. These devices are 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.

Part # L92

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.
