Application Troubleshooting

Media buildup on the probe and stratification are common application concerns. Media 
buildup on the probe is not a problem in most cases, but when it occurs, it can be viewed 
as two types: Film Coating and Bridging. A twin rod probe can be used when minor film 
coating is a possibility. For more extreme buildup, use the Model 7ML1303 or 
7ML1304 Single Rod Probes. 

Level Applications

Continuous Film Coating

The most typical of coating problems where the media 
forms a continuous coating on the probe. SITRANS 
LG200 will continue to measure effectively with some 
small degradation in performance. A problem can 
develop if the product begins to build up on the spacers 
that separate the probe elements. High dielectric media 
(e.g., water-based) will cause the greatest error. 

Bridging

Media that is viscous or solid enough to form a clog, or 
bridge, between the elements causes the greatest 
degradation in performance. High dielectric media (e.g., 
water-based) will show as level at the location of the 
bridging. 

Stratification/Interface

The standard SITRANS LG200 transmitter is designed to 
measure the first air/media interface it detects. 
However, a low dielectric over a high dielectric 
application can cause a measurement problem and 
cause the electronics to trigger on the high dielectric 
medium that lies beneath the low dielectric medium. 
Select the Fixed Threshold option to read the upper 
medium. Example: Oil over water.
