Emerson Rosemount solids level switches

Emerson’s range of Rosemount solids level switches are designed to optimise operations, increase safety and reduce waste by providing reliable point level monitoring and supporting overfill prevention. The switches enable Emerson to offer a portfolio for continuous and point level solids measurement. The vibrating fork, paddle, capacitance and vibrating rod switches within the range monitor solid materials such as powders, grains and pellets in all silo types across industries, such as food, beverage, agriculture, chemical, power, cement, mining and plastics. The compact switches require low maintenance and are suitable for operation in high temperatures, high pressures, dust and risk of explosion.

The switches can provide standalone point level monitoring to help optimise filling and emptying cycles, and can be deployed within an overfill prevention system, to prevent wasted materials, environmental impact and damage to the silo. The Rosemount 2511 and 2521 vibrating fork switches are suitable for applications involving light, fine-grained and powdered materials that require high measurement sensitivity. The switches are certified from the European Commission ATEX (Atmosphères Explosibles) to be installed in explosive areas, and all wetted parts are made from corrosion-resistant stainless steel, making them suitable for hygienic applications.

The Rosemount 2501 rotary paddle switch can be used as a full, demand or empty detector in storage silos or process vessels, as the paddle is designed to withstand heavy loads and temperatures of up to 1100°C. The Rosemount 2555 capacitance switch can be installed in pipes as a limit switch and spillage detector, and is suitable for use with materials that have dielectric values as low as 1.5. It is designed to prevent material build-up when there is a risk of coating. The Rosemount 2535 vibrating rod switch provides high chemical resistance, as it is made of food-grade stainless steel.
