Dwyer L8 FLOTECT Liquid Level Switch
The Model L8 Flotect® Liquid Level Switches are float switches constructed of polyphenylene sulfide, Ceramic 8 and 316 SS. This liquid level switch provides accurate set point control of liquids with specific gravities as low as 0.6.
DIMENSIONS
BENEFITS/FEATURES
- Excellent chemical resistance with float constructed from durable polyphenylene sulfide and leak-proof body
- Longer life and decreased maintenance costs with liquid level snap switch, which is magnetically actuated with no direct mechanical linkage to leak or fail
- Quick and easy installation by simple placement of the unit in a horizontal position with the index arrow pointing down.
- Suitable for mounting in a protected environment with UL recognitionas an industrial motor controller per UL standard 508
