Barksdale UNS-1000 Series (Formerly Series BLS 700) Multi Level Switch

Barksdale's Series UNS-1000 Level Switches offers a level control solution that is fully customizable to the exact needs of your application. Available in lengths up to 40", the UNS-1000 Level Switches can be configured with up to five floats, each with its own individual switch point. A variety of mounting options and materials are available, ensuring compatibility with your vessel. Standard construction materials include stainless steel and brass. Floats are available in stainless steel and Buna-N. Alternative materials may be available upon request. Switches may be configured either as one common circuit (Group 1 or 2) or as independent circuits (Group 3 or 4), with SPST or SPDT reed switches. For applications requiring multiple setpoints with pressures below 220 psi, the Series UNS-1000 is the level switch to choose.
