 S003 Series Level Switch For Dirty and Viscous Liquids   Printer Friendly Version
The S003 is a low cost, single or multiple point level switch designed for use in extremely contaminated or highly viscous fluids Developed for parts cleaners and chemical plating tanks, the S003 features a telescoping float arm that slides in and out of the switch tube which is mounted on the side of the tank and out of the process. The retractable float movement and isolated switch element make it an ideal choice for thick, slurried or corrosive liquids where a conventional float switch will not operate. Available in lengths extended up to 20", the S003 can be furnished with up to two independent switch points and a variety of wiring options and wetted materials.
