Emerson Rosemount solids level switches

Emerson’s range of Rosemount solids level switches are designed to enhance operations, increase safety and reduce waste by providing reliable point level monitoring and supporting overfill prevention.

The vibrating fork, paddle, vibrating rod and capacitance switches provide monitoring of solid materials, such as powders, grains and pellets in all silo types. The switches are suitable for a range of industries, including food and beverage, agriculture, chemical, power, cement, mining and plastics. The compact switches require minimal maintenance and can be operated in challenging environments, including these with high temperatures, high pressures, dust and risk of explosion, as the switches have been certified by the European Commission ATEX (Atmosphères Explosibles).

The switches can provide standalone point level monitoring to help optimise filling and emptying cycles, and can also 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.

All wetted parts of the switch are made from corrosion-resistant stainless steel, making them suitable for hygienic applications. The 2501 rotary paddle switch can be used as a full, demand or empty detector in storage silos or process vessels, as the paddle design can withstand heavy loads and temperatures up to 1100°C. The capacitance switch can be installed in pipes as a limit switch and spillage detector, while the 2535 vibrating rod switch provides high chemical resistance due to its food-grade stainless steel design.
