Product overview
Sigma side mounted float level switches are a compact way to monitor low, intermediate and high levels in tanks. The rugged, quick mounting and maintenance free design is the natural choice for tanks with large insertion depths, or where the top and bottom of the tank cannot be reached.
A small pivoted float is the only part that projects into the tank. These sensitive, accurate switches are typically used on storage tanks, high pressure boilers, sterilisers and process tanks.
