In my opinion an isolator is pointless, for this this reason the development and production (which costs a lot of money initially) hasn`t a high priority anymore at the moment.
This could help:
- if the probe is defective (too old) replace it
- if you have an ungrounded ProfiLux power supply the use of a grounded power supply may help to eliminate the interferences from the Tunze pumps (the latest ProfiLux are shipped with a grounded PSU as standard in order to get rid of problems with noise from 3rd party products)
