Liquid-level on/off point-sensing control
LASC series provides liquid-level and on/off point-sensing control with a self-calibrating, auto-sensitivity feature, eliminating manual adjustment. When liquid reaches the sensing probe, a microprocessor algorithm determines its resistivity, and automatically sets optimum control sensitivity. Single- and multi-level designs are packaged in DIN-rail enclosures for compact panel mounting and powered by 12, 24, 24, 120 or 240 VAC line voltage. If liquid level control and on/off temperature control is needed in a single device, specify the series LASD with pushbutton programming, and separate control relays for on/off liquid level and on/off temperature control using a single RTD probe for single level.
