SITRANS LCS050
SITRANS LCS050 is an ultra-compact capacitance switch for point level detection in constricted spaces, water-based liquids, slurries, and foam.
Product Benefits
- Easy installation with no need for adjustment
- Low maintenance with no moving parts
- Highly visible 360-degree status indication
- M12 connector for ease of installation
- IO-Link communication option for advanced monitoring and configuration
Applications
The SITRANS LCS050's ultra-compact design, short insertion length of 15 mm (0.59 inch), and versatility in various applications in vessels or pipes makes it an excellent replacement for traditional point level switches.
Its advanced alternating capacitance field at the sensor tip ensures material detection based on changes in capacitance, providing repeatable performance. The PEEK probe is chemically resistant with an effective process operating temperature range from ‑20 to +100 °C (‑4 to +212 °F) and supports sterilization in place at 135 °C (275 °F) for up to 1 hour. The product design ensures reliability in vibrating environments such as agitated tanks up to 5 g.
Key Applications
- Water-based liquids with >10% water (alcohols, acids, cleaning agents)
- Slurries and foam for point level detection
- Overfill and dry run protection
- Small pipes due to its compact design
