Rosemount level switches for solids

The vibrating fork, paddle, capacitance and vibrating rod switches within the latest Rosemount range are designed to ensure reliable monitoring of solid materials such as powders, grains and pellets in all silo types across industries including food and beverage, agriculture, chemical, power, cement, mining and plastics.

The switches can be used to provide standalone point level monitoring to help optimise filling and emptying cycles. They can also be deployed within an overfill prevention system, helping to prevent wasted materials, environmental impact, high clean-up costs and damage to the silo.

In applications involving light, fine-grained and powdered materials where high measurement sensitivity is required, Rosemount 2511 and 2521 vibrating fork switches provide a cost-effective solution. European Commission ATEX certification permits installation in explosive areas, and all wetted parts are made from corrosion-resistant stainless steel, making them suitable for use in hygienic applications. The Rosemount 2501 rotary paddle switch can be used as a full, demand or empty detector in storage silos or process vessels. The robust paddle design can withstand heavy loads and extreme temperatures of up to 1100°C.

The Rosemount 2555 capacitance switch can be installed in pipes as a limit switch and spillage detector. The switch is suitable for use with materials that have dielectric values as low as 1.5 and is designed to prevent material build-up in applications where there is a risk of coating. The Rosemount 2535 vibrating rod switch provides high chemical resistance due to the fact that it is completely made of food-grade stainless steel.
