Vibrating Fork Level Switches

Vibrating Fork Level Switches Utilize a Piezoelectric-Driven Tuning Fork that Exhibits a Large Change in Resonant Frequency when Immersed into a Liquid or Bulk Solid Process. A "Smart" Microprocesso-Based Electronic Unit Keeps the Sensor in a Resonant State as it Changes from Dry to Wet or Wet to Dry. An Important Feature of this Switch is that its Resonant Frequency is not Significantly Affected by Coating on the Fork Until the Space Between the Forks is Bridged. Applications Include Redundant High/Low Process Levels without Concern for Parameters, such as Specific Gravity, Dielectric Constant or Mounting Position of the Sensor.

Resonator RS80 Vibrating Liquid Level Switch Model RS80 The Resonator utilizes a piezoelectric driven tuning fork that exhibits a large change in resonant frequency when immersed in any liquid. A "smart" microprocessor-based electronic unit keeps the sensor in a resonant state as it changes from dry to wet or wet to dry. The resonant frequency is continuously monitored for changes created by a wet or dry sensor and an alarm is provided via relay. See the RS85 data sheet for optional process connections, coatings and materials of construction for more difficult applications. More... Resonator RS85 Multi-option Vibrating Liquid Level Switch Model RS85 The Resonator utilizes a piezoelectric driven tuning fork that exhibits a large change in resonant frequency when immersed in any liquid. A "smart" microprocessor-based electronic unit keeps the sensor in a resonant state as it changes from dry to wet or wet to dry. The resonant frequency is continuously monitored for changes created by a wet or dry sensor and an alarm is provided via relay. The RS85 should be used when the application requires optional process connections, exotic materials of construction, coatings, finishes or adjustable time delay and density set point. More...

GP50 Vibrating Level Switch for Powders and Granular Solids Model GP50 The GranuPoint 50 is a Vibrating Level Switch that Detects the Absence or Presence of Dry Bulk Solids in Bins, Silos or Hoppers. The GranuPoint 50 is a Compact and Robust Design, Suitable for Top or Side Mounting. The Constant Vibration of the Fork Tine Provides Self-Cleaning Characteristics for Products that Do Not Coat or Cake. The Unique Design of the Fork and Crystal Asembly Eliminates False Level Readings. The Model GranuPoint 50 can be Used in Products that do not have Heavy Build-up on Forks. The GranuPoint 50 can Handle Dense Materials, such as Cement (80 pcf) to Extremely Light Products like Styrene (2 pcf). A Wide Range of Applications are Also Found in Dry Food Processing. More... SP60 Vibrating Level Switch Interface Measurement for Solids in Liquids Model SP60 The SludgePoint 60 is a Vibrating Level Switch Designed for Interface Detection of Solids in Liquids. The SludgePoint 60 Solid/Liquid Interface Units do not Sense Liquid but will Sense the Presence of Submerged Solids, such as Plastic Resins, Clay, Carbon Granules, Sand and Corn. It is Ideal to use when Emptying bins with a High Sediment Level or Maintaining Level of a Submerged Solid. The SludgePoint 60 is a Compact and Robust Design, Suitable for Top or Side Mounting with 1-1/2" NPT Standard Process Connection. The Unique Design of the Fork and Crystal Assembly Eliminates False Level Readings. More...
