Steve, can you provide more details such as: The type of fluid and the conductivity The physical relationship between your equipment and the application? How is the fluid piped? The RF frequency? What is the symptom that you observe? Here is my first thought assuming that the chiller pipes the fluid to and from the application through non-conductive hose and that the fluid is conductive. Yes the fluid could provide a conductive path for RF. To prove/disprove this theory the impedance of the suspected RF path could be temporarily altered by: Changing the fluid type Placing a wire connecting the chiller to the application and running along the tubing Placing ferrite cores over the tubing Then see if there is a change in the symptom. Or, the RF current flowing in the fluid can be measured with a clamp-on RF ammeter over the tubing.

We have a chiller installed in a customer application where RF is used in their process, but we believe RF is being transmitted to our product via the fluid. Soe anh one have any suggestions on how to measure RF in fluids - type of equipment, etc.? Thanks in advance and best wishes o the EMC/PSTC Family for a happy and healthy holiday season, Steve Brody ( [email protected] <mailto:[email protected]> )
