A modular chemical delivery system is designed to be readily convertible from use with a warewashing system to use with a laundry system, or vice-versa, merely by the replacement of one chip in the controller of the system. The dispensing system is also readily expandable by adding additional satellite pumps in order to inject additional chemicals into a single washing unit, and/or to supply chemicals to additional washing units. Plug and play technology is used so that control intelligence can be distributed from the main system controller to satellite controllers, and so that additional satellite units may be readily added, identified, and properly integrated into the dispensing system.

An Inductive Probe/Conductive Probe Emulator is designed to replace conductive probes at a much lower cost than existing inductive probe systems. The conductivity probe simulator is usable with any industrial controller that uses a standard two wire conductivity probe interface. A continuously variable semiconductor resistive element is employed to match the conductivity of any conductive probe. The system uses the inductive probe reading to adjust the resistive element to the correct value. The conductivity probe simulator can be configured to emulate any conductivity probe with any probe constant by downloading configuration parameters to the probe controller or by setting configuration switches on the controller module. Additionally, the inventive probe simulator is equipped with an embedded temperature sensing element, giving the system a capability to perform a temperature correction in the controller section, if necessary.
