Rf Capacitance Level Switch

The Hopper Level Switch is designed to provide accurate and reliable point level detection for solids (powders and lumps), liquids, and slurry stored in vessels, silos, and hoppers. This advanced level switch ensures precise monitoring of high and low levels, making it ideal for industrial applications.

The electronics consist of an oscillator, a detector, and an output relay, which work together to detect level changes efficiently. The Hopper Level Switch probe includes an active section and a shield section, both insulated from each other and the vessel ground. This design enhances measurement accuracy while preventing false readings.

Unlike conventional sensors, the Hopper Level Switch is engineered to ignore material buildup or coating, ensuring consistent performance even in challenging environments. This feature makes it a reliable choice for applications where material adhesion can cause incorrect level indications.

With its robust design and high precision, the Hopper Level Switch is widely used in industries such as food processing, cement, agriculture, and chemical processing, ensuring optimal material management and process efficiency.

The Hopper Level Switch is designed for precise point level detection and process control in a wide range of industries. It ensures reliable monitoring of solid, liquid, and slurry materials, making it an essential component in industrial storage and processing systems.

Key Applications of Hopper Level Switch:

Used in bins, vessels, tanks, chutes, and conveyors for accurate level monitoring.
Ideal for industries handling plastics, chemicals, coal/fly ash, and concrete.
Ensures precise level detection in food ingredients, pharmaceuticals, and animal feed storage.
Widely applied in grain storage, mining, foundries, and wood or paper processing.
Suitable for various industrial materials, improving efficiency and safety.

With its high accuracy and durability, the Hopper Level Switch is a reliable solution for ensuring optimal material flow and preventing overfill or dry-run conditions.

The Hopper Level Switch operates on the RF capacitance principle, detecting the presence or absence of material by sensing minute changes in capacitance (as low as 0.5 pF). These changes occur due to the difference in the dielectric constant between the stored material and air, allowing for precise and reliable level monitoring.

Key features of the Hopper Level Switch include:

Interference-free operation, ensuring accurate level detection in industrial environments.
Simple calibration for easy setup and maintenance.
Fail-safe functionality to prevent false readings and enhance system reliability.
Superior performance in dusty, sticky, or clinging materials, making it ideal for challenging applications.
Class II hazardous location ratings for safe use in various industrial settings.

The Hopper Level Switch comes with a wide assortment of probes and extensions, making it suitable for solid, liquid, and slurry materials stored in hoppers, silos, bins, and tanks. Its high precision and durability make it an essential component for efficient material level monitoring in industries such as cement, food processing, pharmaceuticals, and mining.
