Barksdale UNS1000-BN18 Level Switch/Temperature Option

The UNS1000-BN18 is a top mount level switch that offers a choice of four different process connections, three electrical terminations and an optional temperature sensor. With a maximum stem length of 23.6 inches, the UNS1000-BN18 can be customized to the exact stem length you need. The brass stem and Buna-N float ensure broad chemical compatibility and are ideal for most hydraulic oils and water. Barksdale level switches have performed reliably for years in applications as diverse as Solvent Recovery Systems, Marine, HPU Reservoirs and Sump Tanks.
