SITRANS LCS100 is a versatile point level switch designed for detecting level in liquids, solids, slurries, foam, and interface applications. Its compact design makes it ideal for confined spaces, with options for plastic or stainless steel process connections and flexible rod/cable probe extensions.
SITRANS LCS100 offers flexible insertion lengths starting at 92 mm (3.6 inches) and provides versatile performance in various applications across vessels and pipes. Its advanced design ensures accurate, repeatable switchpoint performance.
The PPS probe (optional PVDF) and optional PEEK materials provide excellent chemical resistance with an operating temperature range from -40 to +125°C (-40 to +257°F). The fully potted design ensures reliability in vibrating environments like agitated tanks. When used with SensGuard protection cover, the LCS100 is protected from shearing, impact, and abrasion in demanding processes.
Available with stainless steel or polyester enclosures and stainless steel or PPS process connection options.
