Interface measurement for cathode gold deposition in electrolyzer

The Challenge

A gold mining company in Sakhalin Area in Russia needed to detect the interface of cathode gold deposition in electrolyzer cone to prevent short circuits between cathodes and anodes. Process preassure 5 bar, temperature up to +150°C. Liquid medium: alkaline solution NaOH 5%. Solid medium: slurry of cathode gold particles. The company was looking for a sensor to do this.

Our Solution

The solution is a vibrating fork for interface measurement VN 1020. The electronic has a adjustable sensitivity to find the right switchpoint. The robust stainless steel probe in 316L is perfect in this application.
