Early warning

The ability to monitor two conductivity cells using a single transmitter was a key factor in Eon's decision to replace obsolete conductivity instrumentation at Kingsnorth power station with dual channel transmitters from ABB.

Conductivity meters are used to sample the station's high-purity boiler water and the turbine condenser water purity. Although not immediately critical to the station's operations, they detect any build-up of impurities and provide an early warning of contamination.

The contract included 23 AX400 Series dual input transmitters, 13 AC220 conductivity cells, 33 AC220 cells and 44 flow chambers.
