Durable magnetically actuated level switch

July 14, 2008

K-TEK recently introduced the MS41, the industry''s most durable, magnetically actuated electric switch, according to the manufacturer. The MS41 features a compact, dual-compartment design that isolates the 10 ADPDT (double pole, double throw) switching mechanism from the environment. Electrical connection is made through a hermetic seal within the enclosure that protects the internal mechanism from moisture and heat damage over an extended period of time. The rugged, NEMA 4X, stainless steel enclosure ensures the MS41 can be used in even the most corrosive, offshore environments and can handle a wide range of demanding uses, including high temperature (up to 1000˚F/538˚C) and high vibration applications, such as pump and compressor skids. The MS41 Magnetically Actuated Electric Switch features a unique cam action switching mechanism. There are no bias springs to adjust or maintain as parts age, therefore the switch requires no maintenance - no cleaning and no operational checks -- and provides more reliable performance. The trip point is infinitely adjustable along the length of a magnetic level gauge without changing the process piping. The switch is housed in a 316L stainless steel, dual compartment, NEMA 4X enclosure. It meets the requirements for use in hazardous areas and is ATEX, FM, and CSA rated as Explosion Proof and Intrinsically Safe.
