Dielectric Range
10.000 cP – consult factory in case of
1500 cP
agitation/turbulence
ε ε _r 10-100 (depending installation conditions down
ε to _r ≥ 1.9) – liquids
ε_r 4-100 – solids
r ^1.9-100
Mechanical load
20 lbs (9 kg) – 7x1
Pull-down force
3000 lbs (1360 kg) – 7x2
3000 lbs (1360 kg) – 7x5
Media coating
Maximum error of 10% of coated length. % Error is related to dielectric of medium, thickness of
coating and coated probe length above level.
ε Œ Transition Zone (zone with reduced accuracy) is dielectric dependent; r = dielectric permitivity. It is recommended to set 4–20 mA signal outside the transition
zone / blocking distance.
