Technology:

The non-intrusive RF capacitance switch detects the pres-
ence of liquid or air by measuring the conductive or dielec-
tric values which are present in all materials. An electrical
capacitor is formed between the level switch and the outer
tank wall. As liquid rises and falls against the inner wall, the	2
capacitance effect is greatly increased and the 1A SPST	.

NOTE: Liquids with a conductivity value > 100 µU are fine if coating is not an issue. Liquids with a dielectric constant less than 20 may not be reli- ably detected by an LVP-51 series level switch, depending on conditions.
