The Delta M Corporation microtuf® LS3200 Single Channel Point Level Switch is a thermal differential point-level switch used for liquid level detection in vessels.
It is designed for industrial applications where a discrete level change must be detected without relying on moving mechanical components.
As part of Delta M Corporation’s LS3200 Series Basic Point-Level Switch family, the microtuf® LS3200 supports liquid level monitoring applications such as truck and railcar loading, immersion heater protection, reactor/vessel charging, and tank leak detection.
