Problem
Solution
No output change with level change
Check wiring; verify that the correct input
voltage is applied
Verify that liquid is filling the sensor gap
Check for dense foam or dried product in
the gap. Switch may not function properly
if either condition exists.
Check sensor phono plugs for a good
connection. Unplug and Re-plug each
connection.
Check for excessive aeration in process
fluid. This is particularly important in
viscous fluids.
The output is “chattering”
Check wiring; verify that the correct input
voltage is applied
Check for turbulence. Relocate switch or
isolate from turbulence
Check for excessive aeration in process
fluid. This is particularly important in
viscous fluids.
