SA Series Capacitance Level Switch

The Fine-tek Capacitance Switch for liquids and solids can be used in mediums such as liquids, pastes, syrups, powders, granules, flakes and chips. It’s broad application and rugged build makes it a highly versatile across all industries. Capacitance switches rely on electrical capacitance theory (the ability of a medium to store electrical energy). When an electrical circuit has two separated conductive plates, the space between the plates acts as a capacitor and stores the electrical energy. Mediums have differing conductivity and dielectric constants which affects their energy sstorage capability. When the switch comes into contact with the medium, it can detect a change in the surroundings and this actuates the switch accordingly. Materials with high conductivity or high dielectric constants such as water tend to have high capacitance. The opposite applies for low conductive substances such as popcorn, wax or air. Thus the switch works well in mediums with reasonably high dielectric constants or conductive solutions..

SE Series

The SE series operating principle is simple. A unit is usually located through a bin wall at the top, middle or low level of a bin. During normal operation (no material present) a synchronous motor rotates the paddle at 1 RPM. When this paddle rotation is impeded by material, surroanding the paddle, motor will stall and cause the Micro switch to change state. (indicating an alarm or control) Product Introduction

FA/FB Series

The FA/FB Series is a cable float level switch product line constructed from a variety of chemical resistant materials. These are durable, low-cost, simple and easy-to-use float level switches equipped with either a microswitch, reed switch or mercury switch output.
