Sigma Series 1500 Float Level Switches are specifically designed to meet the harsh conditions found in industrial, municipal, environmental and machine level control applications. Available with up to four (4) level stages, the Series 1500 utilizes hermetically sealed reed ease of installation in tanks, drums or sight switches actuated by a magnetic embedded in the glass. Floats are restricted in their movement by positive float stops.
A non-metallic weatherproof head contains a screw terminal barrier strip for field connections through a tank top mounted fitting. Floats are provided as standard in 316SS or Buna N, however, many other non-metallic materials are available as special order. 1-1/2" or 2" NPT process connections facilitate ease of installation in tanks, drums or sight glass. Multiple stage independent switches permit both pump control and alarm functions to be carried out by a single switch assembly, easily installed.
