D=Minimum distance from end of unit to lowest actuation point
The SERIES F7-MS Multi-Station Level Switches provides a customized level switch
to meet application requirements. Switches can be configured with up to six different
control points and stem lengths up to 140˝ (3.56 m). Stems and floats are available in
316 SS or brass, SPST or SPDT switches, and choice of mountings.
FEATURES/BENEFITS
• Customized level indication quickly and affordably
• Rugged construction with multiple options yielding exceptional versatility
• Capable of supporting larger, more buoyant floats
• Durable construction asserts long reliability in contaminated or turbulent media
