Siemens LCS 100
SITRANS LCS100 is a point level switch designed to detect point level in liquids, solids, slurries, foam, and for interface detection. Its compact design makes it ideal for use in confined spaces and offers plastic or stainless steel process connections along with flexible rod and cable probe extensions. SITRANS LCS100 is utilised for overflow, high, low, and demand applications, as well as for pump protection. It operates effectively in all types of vessels, pipes, and silos across a broad range of industries, including food, pharmaceuticals, chemical, petrochemical, water, and machine building.
SITRANS LCS100's flexible insertion length, starting at 92 mm (3.6 inch), and its versatility across various applications and within vessels or pipes, makes it a suitable choice for most point level applications. Its advanced design ensures accurate and repeatable switchpoint performance. The PPS (Polyphenylene sulphide) probe [optional PVDF (Polyvinylidene Fluoride)] and optional PEEK offer chemical resistance with an effective process operating temperature range from ‑40 to +125 °C (‑40 to +257 °F). The fully potted design ensures reliability in vibrating environments such as agitated tanks. When used with a SensGuard protection cover, the LCS100 is protected from shearing, impact, and abrasion in demanding primary processes.
The SITRANS LCS100 is available with either a stainless steel enclosure or a polyester enclosure, and offers stainless steel or PPS process connection options.
Key Applications: liquids, slurries, powders, granules, food and pharmaceuticals, chemicals, hazardous areas.
