Dual-element Probes
55 57-600 Eclipse ® Guided Wave Radar Transmitter
Single Rod Probes
Distance to Probe Acceptable Objects
<6" Continuous, smooth, parallel conductive surface; e.g., tank wall.
Important that probe does not touch wall.
<6" <1" (25 mm) diameter pipe and beams, ladder rungs
<12" <1" (75 mm) diameter pipe and beams, concrete walls
<18" All remaining objects
SINGLE ROD PROBE CLEARANCE GUIDELINES TABLE
NOTE: Transition Zone is dielectric dependent;
ε
r = dielectric permittivity. The transmitter still operates but
level reading may become nonlinear in Transition Zone.
