This process instrumentation diagram details loop connections for pH and conductivity analyzers powered by 24-volt direct current. The system incorporates analytical instruments including a pH analyzer designated DP933B1 and a conductivity analyzer designated DP933A1 with tag number SE020FP900. A flow pace Profibus-IO module with designation DP933A1-AO is integrated into the monitoring line. Interconnecting wiring and signal loops link the field sensors to the shared communication bus.
