LS-10 general-purpose three-wire models provide level measurements at depths of 0.5-24.5 ft to an accuracy of ۪.25 percent. A tight eight-degree beam operates in restricted-spaced environments. Inch and centimeter measurements are displayed on a digital LED, and an integral 10 A/250 Vac relay is included for direct actuation of pumps, valves, and alarms. The polypropylene enclosure is rated at NEMA 4X, and a two-wire version offers a range of 0.5-18 ft and CE/CSA approval for intrinsic safety.

The LS-20 two-wire point level switch is designed for in-tank or tank-side entry. The relay or FET output provides a reliable switch interface with such remote devices as PLC, SCADA, and alarm. Sensor rating is NEMA 6 (IP68) and includes CSA/NRTL (UL) and CE approvals with selectable switch state of NO and NC and accuracy of ۫ mm in water with ۪.5 mm repeatability.

The LS-50 proportional relay controller/indicator features three sensor inputs and two relay outputs. The failsafe design allows direct actuation of pumps, valves, or alarms, and LED indicators display sensor, relay and power status. Units mount on a 35 mm DIN rail or panel-type installation.
