Choosing the correct switch materials can
often mean the difference between years of dependable service
and equipment failure. Materials that work well in oils or
petroleum products may not be the best for common detergents
or hot water.
- Stainless Steel - Ideal for high temperatures,
high pressures and corrosive environments such as food equipment,
industrial tanks or durable general use.
- Brass, Nylon or PBT stems with Buna-N Float -
Good for petroleum products, oils and wastewaters. Buna-N
floats have superior buoyancy and can be configured for
oil-water interface detection.
- General Use Plastics - Polypropylene, PVC and
Polycarbonate good to 105 degrees Good choice for general
use, acids or food applications. Can be designed economically
or custom molded with additional features for OEM applications.
