L10 Level Controls - Sherman Instruments

Mini-Size Level Switch is UL Recognized and CSA Listed

The Series L10 Flotect line of compact, low cost float actuated level switches. Two Basic confiurations are available: 1" NPT male threads for direct side mounting through a half coupling or with a factory installed 1" tee for external mounting. All Series L10 switches feature a hermetically sealed, SPST magnetically actuated reed switch with a unique patented mechanism for quick, positive changes between normally open and normally closed operation.

Three types of floats are offered to accommodate liquids with specific gravities as low as 0.5 and maximum pressures to 2000 PSIG. Wide media compatibility is assured with a choice of brass or stainless steel bodies and external tees; polypropylene or stainless steel floats.

All models are UL recognized and CSA listed.
