Float Switch Handling

Product Description

This mini vertical float switch offers dependability for general use at cost effective prices. For general use, potable water or acids, a polypropylene level switch is just what you need, while a nylon level switch with Buna-N float provides superior buoyancy for petroleum fluids and oils. Only 1/4″ larger than the FS25, the FS12 is suitable for any applications where there are tight space constraints

This vertical level sensor design is available with 1/8″ NPT or 3/8-16 Bulkhead threads and can be manufactured in custom colors or materials. Functionality is retained at a maximum temperature of 110°C and max PSIG of 100 with Buna-N float. Both models feature a 50-watt switch.

These inexpensive vertical float switches are good for everyday applications in the food and beverage industry. For example, for monitoring a restaurant’s grease traps to ensure they are cleaned at the right time. Also to ensure waste oil containers are properly emptied are also important for the safety of occupants and the public.
