Min. Fluid SG
Must close level (SG=1)
Must open level (SG=1)
These devices are particularly suitable for
detecting low levels of liquids in the
bottom of tanks and containers, and for
lower SG liquids. Typical applications
include vending machines, commercial
dishwashers and auxiliary tanks on
vehicles.
* ETFE cable needs to be selected in order to achieve the maximum temperature rating
