- Model LSA01 Series - Capacitance Level Switch Single Point Detection



AYSIX LSA01 series level switches are highly reliable microprocessor based sensors designed to alarm on the high or low condition of liquids and certain dry bulk media in metal tanks. The LSA01 includes a transmitter housed in a rugged enclosure, a rigid probe up to 20 feet long and a fitting. Probe material is SS316, supplied bare or PFA jacketed. Additional standard features include and adjustable time delay, SPDT relay, LED relay status indication, and a simple push button calibration.

The LSA01 senses level using RF capacitance measurement technique together with microcontroller technology for high resolution point level detection. A probe mounted in a vessel forms a capacitor with the vessel wall. The capacitance of the configuration is measured by the LSA01 and is used to provide point level switch control. Hi and low alarms are easily set with push-button convenience for differential level applications such as pump control. For vertical probes with a setpoint along the length of the probe, a consistent material dielectric will ensure a consistent and repeatable alarm point.

  • Detecting a single point, tip sensitive or at any point along the probe
  • Detecting high or low level
  • Detecting level of liquids, solids, slurries, foam
  • Operating in any shape of metal type vessel
