Magnetically actuated electric switch


K-TEK, a leading manufacturer of
state-of-the-art instrumentation for level measurement, today announced the
MS41, the industry's most durable, magnetically actuated electric switch.
The MS41 features a compact, dual-compartment design that isolates the 10 A
DPDT (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 1000šF/538šC) 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 MS41 is the most durable, magnetically actuated switch on the market
today," stated Kevin Hambrice, Director of Marketing and Customer Service at
K-TEK. "The cam driven, snap action, bistable switch means no bias springs
to maintain. And mounting and adjustment is easy...only a screwdriver is
required. The stainless steel, dual-compartment chamber provides exactly the
kind of robust housing needed for corrosive, offshore applications like oil

The MS41 switch can be used with K-TEK's KM26 Magnetic Level Gauge, LS
Series Cage Level Instruments, or an external chamber that contains a
magnetic float. The MS41 senses high or low levels within a vessel. The
unique, magnetic coupling action eliminates the need for seals, diaphragm
springs, or torque tubes because there is no physical contact with the

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.
