Barksdale UNS-2000 Series (Formerly Series BLS 800) Multi Level Switch

Barksdale's Series UNS 2000 Level Switches offer a level control solution that is fully customizable to the exact needs of your application. This series of Level Switches can be configured with up to six floats, each with its own individual switch point. A variety of mounting options and materials are available, ensuring compatibility with your vessel. Floats are available in stainless steel and Buna-N, ensuring a broad range of media compatibility. 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, an integral temperature switch (optional) and high pressures up to 580 psi, the UNS-2000 is the level switch to choose.
