Level switches offer choice of float designs

A K-Tek product story

The MS50 is the latest version of the low-cost float level switch from K-Tek.

The MS50 is the latest version of the low-cost float level switch from K-Tek.

Priced up to 25% less than competing models, the MS50 is designed to reliably handle a wide range of applications, including sump level control, alarms and shutdowns.

Each switch features application-specific float designs that optimise performance and reliability in the fluid being measured, whether butane, propane, oil, acid, water or interfaces between two fluids.

A unique magnetic coupling ensures optimal switch performance throughout the life of the unit.

The MS50 can be equipped with up to six SPDT switch points per unit.

For maximum up time, a K-Tek latching switch design allows each point to be adjusted and replaced in the field.

The MS50 is FM approved and CSA certified for use in hazardous areas.

A high-temperature option handles process temperatures up to 149C.

For high vibration/shock applications, such as transportation, a multiple-float option uses special nonlatching reed switches and stop collars to guarantee reliable switching.

"K-Tek's switches are designed for the needs of today's production operations, maximising flexibility and minimising down-time", said Kevin Hambrice, Director of Marketing, K-Tek.

"The MS50 can be adjusted in the field, without removing the vessel from service.

And K-Tek's broad range of float designs ensures a match for the specific gravity of virtually any fluid.

Competitive float switches are limited to only a few available float designs, mounting configurations, and measuring lengths.

They must be pre-configured in the factory and are designed such that if one contact fails, the entire unit must be replaced".

The MS50 features hermetically sealed, magnetically biased, single pole-double throw (SPDT) reed switches.

Each unit can include up to six switches for applications requiring multiple switch points or redundancy.

Due to the unique nature of the internal switches, the MS50 requires only one float for operation in single fluid applications.

For high vibration/shock applications, such as transportation, a multiple-float option uses special nonlatching reed switches and stop collars to guarantee switching.

The MS50 works in tanks of nearly any shape, size, or type.

Most variables are easily accommodated, including tank depth, type of fluid, and changes in specific gravity.

Multiple options handle environments up to 55bar at 149C.

Lengths range from 0.2 to 6m.

Retrofitting to an existing vessel is made easy with process connections that can be specified from 0.75 to 4in NPT, and flange sizes from 1in up.

Each MS50 features an application-specific float design optimised for the specific gravity of the fluid being measured.

K-Tek provides the largest selection of float designs, including 14 standard and hundreds of custom options.

K-Tek also has the largest selection of float and flange materials in the level industry.

Choices for float materials include 316 stainless steel, Alloy 20, C-276 Hastelloy, PVC, CPVC, Kynar, Tefzel and Halar.

This means the MS50 can handle high temperatures or corrosive fluids, such as hydrochloric acid.

Oversized floats are available for applications where a certain degree of build-up is anticipated.

The MS50 is FM approved and CSA certified for use in hazardous areas.

The standard housing is powder-coated aluminium; an optional stainless-steel housing handles corrosive environments.

The MS50 is also available with PVC, CPVC or Kynar wetted parts.

External relays are optionally available for the MS50.

The IR10 interposing relay output module is designed for process control equipment that may require a higher operating current than can be provided by most switches.

The PP10 latching relay provides control of on/off devices, such as motors, motor starters, solenoids, and alarms.

Both units are easily mounted and installed.

Each is supplied in an explosion-proof enclosure with terminal blocks for fast access to field wiring.

K-Tek's MS50 float level switches are available for immediate shipment.

Prices start at $465.

Prices for the IR10 interposing relay output module start at $168, and for the PP10 latching relay start at $200.

Delivery is one week from receipt of order.
