Using a Conductivity Controller in a Washer

Q. How does a conductivity controller regulate a dosing pump in a machine washer?

A. A conductivity probe would need to be set up in the sump of a machine washer. The conductivity recorded is sent to the conductivity controller that regulates the pump (usually a peristaltic pump) that dispenses the detergent into the sump. The pump dispenses until the correct conductivity is reached for the desired concentration. Typically a concentration of 0.5% or 0.1% detergent is desired.
