Jerguson® External Cage Level Switches
Jerguson® products are also available under the Magne-Sonics® brand as required based on approved vendor specifications.
Jerguson offers a wide array of mechanical switch and transmitter products to provide reliable level measurement for your application. Our caged level switch products feature a unique, tri-magnet mechanism that offers high current, snap-action switching without the use of cams or springs. Products are available with ASME B31.1/B31.3, FM, UL, CSA, ATEX, & PED approvals.
The heart of the Jerguson Level Switch is its unique Tri-Magnet latching design. Not only is it mercury-free, its positive snap action eliminates the tendency of other switches to stick. There are no springs to fail, meaning that you’ll also save costs by eliminating frequent switch mechanism replacements. |
