6.9 Static Electricity
Static electricity can cause the 4-20 mA output to appear
to jump around in an erratic fashion with a time period
of few seconds. Applications that are prone to static
electricity include insulating liquids that may be agitated
or pumped and granulars that may be air-conveyed at
high rates of speed. Conductive liquids and conductive
granulars tend not to generate static electricity. In
addition to causing erratic readings, static electricity can
cause instrument failure. If you ever get a static shock
from a sensing element, you need spark protection. (See
section 2.5)
Drexelbrook normally supplies static electricity discharge
devices (spark protectors) with its sensing elements that
are going to be used in these types of applications. If you
need a spark protector, contact the Drexelbrook Service
department.
6.10 Radio Frequency Interference
All Drexelbrook transmitters have a significant amount
of RFI protection built in. There are situations, however,
where the standard protection is inadequate. RFI filters
are available to provide additional protection for both
the sensor and the 4-20 mA loop from unusually difficult
sources of interference. Proper grounding and careful
attention to installation practices can usually make them
unnecessary. Some recommended installation practices
include:
1. Use twisted shielded cable for the 4-20 mA loop.
2. Use grounded metal conduit for all entrances to the
transmitter housing.
3. Ground the transmitter housing to a good earth
ground.
4. Use concentric shield sensors in non-metallic
vessels.
If RFI continues to be a problem, contact the Drexelbrook
service department for the proper filters and assistance.
