Barksdale UNS-PA or PP (Formerly Series BLS-7) Level Switch - Plastic

Barksdale's UNS-PA/PP family of level solutions are ideal for applications requiring a side-mounted switch. With their compact design, they are suitable for use in small tanks and vessels, as well as larger tanks where top mounting is not an option. A choice of polyamid (nylon) or polypropylene wetted parts allows for broad media compatibility and assures trouble-free operation over a wide range of media temperatures. Switch polarity can be changed from normally open to normally closed by simply rotating the assembly 180 degrees. For applications requiring a durable yet economical side-mounted level switch, the UNS-PA/PP is the solution.
