In general glass pH electrodes are not suitable for food applications due to the risk of broken glass fragments contaminating the process. Furthermore, many designs of pH electrode need to be removed from the process stream before the CIP process can be completed. One solution could be the Type 8201 pH measuring system from Bürkert, which employs a hygienic, robust and glass-free design that can withstand high temperatures and can be sterilised in situ.
In addition, the smooth enamel external surface of the probe inhibits the process medium from sticking to it and is very easy to clean. By using industry standard signals, these pH sensors can either be integrated into an existing process control system or used in conjunction with other control components.
