Abstract

A multifunction rotating disk sensor apparatus is used to continuously monitor changes in bath parameters, such as temperature, pH, additive concentration, etc., within the plating tank. The sensor apparatus is located with the rotating disk electrode to allow for accurate measurement of bath characteristics. In the figure, the body 1 of the apparatus is shown detached from the sensor head 2. The body 1 is rotated by an electric motor through an interconnecting shaft 3 which is made to be compatible with commercially available rotating disk assemblies. An intermediate shaft 8 is connected to drive shaft 3 via threads 9. Electrical contact to the rotating assembly is with a set of brushes 4 mounted as a unit 5 and secured to the stationary cylindrical wall 6 of the motor housing.

Multifunction Rotating Disk Sensor

A multifunction rotating disk sensor apparatus is used to continuously monitor changes in bath parameters, such as temperature, pH, additive concentration, etc., within the plating tank. The sensor apparatus is located with the rotating disk electrode to allow for accurate measurement of bath characteristics. In the figure, the body 1 of the apparatus is shown detached from the sensor head 2. The body 1 is rotated by an electric motor through an interconnecting shaft 3 which is made to be compatible with commercially available rotating disk assemblies. An intermediate shaft 8 is connected to drive shaft 3 via threads 9. Electrical contact to the rotating assembly is with a set of brushes 4 mounted as a unit 5 and secured to the stationary cylindrical wall 6 of the motor housing. Electrical signals from the head 2 are passed to external processing electronics through a connector socket 7. The brushes 4 contact conducting rings 11 which are electrically isolated from each other and the shaft with insulating rings 12 and an insulating sleeve between the rings and the shaft (not shown). The shaft 8 is slotted to allow for easy wiring 13 of the conducting rings 11 to the multipin socket 14 of the bayonet connector 11 for connection to head 2. For the multifunction head 2, electrical connection is made to the body 1 by male connector 15. The cylindrical head 2 is constructed of chemically inert material, such as TEFLON* and is mechani...
