SITRANS LCS100
SITRANS LCS100 is a point level switch that detects point level in
liquids, solids, slurries, foam, and interface detection. Its
compact design is ideal for confined spaces with plastic or
stainless steel process connections and flexible rod and cable
probe extensions. SITRANS LCS100 is used for overflow, high, low,
and demand applications as well as pump protection. It works in all
types of vessels, pipes, and silos in a broad range of industries
including food, pharmaceuticals, chemical, petrochemical, water,
and machine building. | | | | 7ML700.-.....-.... | 7ML701.-.....-.... | 7ML702-.....-.... | 7ML703.-.....-.... |
Benefits
Potted construction provides protection from shock and vibration
Factory calibrated to work in most applications without tuning
Active shield and tunable to compensate for build-up
Optional IO-link communication and remote testing
Options for plastic or Stainless steel enclosure and M12 connection Application
SITRANS LCS100's flexible insertion length, starting at 92 mm (3.6
inch), and its versatility in various applications and in vessels
or pipes make it a good fit for most point level applications. Its advanced design provides accurate, repeatable, switchpoint
performance. The PPS (Polyphenylene sulfide) probe [optional PVDF
(Polyvinylidene Fluoride)] and optional peek are chemically
resistant with an effective process operating temperature range
from ‑40 to +125 °C (‑40 to +257 °F). The fully potted design
ensures reliability in a vibrating environment such as agitated
tanks. When used with a SensGuard protection cover, the LCS100 is
protected from shearing, impact, and abrasion in tough primary
processes. The SITRANS LCS100 is available with either a stainless steel
enclosure or a polyester enclosure and stainless steel or PPS
process connection options. Key Applications: liquids, slurries, powders, granules, food and
pharmaceuticals, chemicals, hazardous areas Configuration Technical specifications
