Pneumercator LS 600

Pneumercator LS 600

Item #LS600

The Pneumercator LS 600 series liquid level float switches provide the highest degree of dependable accuracy for sensing and controlling liquid levels. They may be used with audible alarm consoles such as the Pneumercator LC 1000 or customers' own to actuate high and/or low level warning devices. The LS 600 is available with intermediate switches for control of pumps to maintain liquid levels within a predetermined range. The LS 600 series is simple in design and operation. A magnet within each float actuates a hermetically sealed dry-reed switch. The encapsulated switches are sealed inside the sensing probe and completely protected from exposure to liquid or vapor. Float travel is restricted via the use of stops placed immediately above and below the customer specified switch operating points.
