2.3.5 Troubleshooting Application Issues

There can be numerous reasons for application-related
issues. Media buildup on the probe is covered here.
Media buildup on the probe is typically not a problem in
most cases— Genesis circuitry works very effectively. Media
buildup should be viewed as two types:
• Continuous Film Coating
Film
• Bridging
Coating
Continuous Film Coating
One type of potential application problem is when the
media forms a continuous coating on the probe. Although
the Genesis will continue to measure effectively, some small
inaccuracies may occur as the signal propagation is affected
by the thickness, length, and dielectric constant of the
coating.
It is a very rare case where filming causes a noticeable per-
formance degradation.
Bridging
A more common coating problem occurs when the process
Bridging
medium is viscous or solid enough to actually clog, or
bridge, between the elements. This bridging can cause a
noticeable degradation in performance. For example, high
dielectric media (e.g., water-based) can be detected as level
at the location of the bridging.
Similarly, a problem can develop if the product begins to
build up on or near the spacers that separate the probe ele-
ments. High dielectric media (e.g., water-based) will cause
the greatest error.
Refer to Section 2.6.4 for viscosity specifications on the
various Genesis probes.
Optional Flushing Connection
The maintenance of probes in applications containing
buildup or crystallization can be significantly improved by
using an optional flushing connection. This flushing con-
nection, which is available with both probe styles, is a metal
extension with a port welded above the process connection.
The port allows the user to purge the inside of the probes
during routine maintenance.
Contact the factory for any questions regarding
applications with potential coating and buildup.
