Blind Transmitters: A return to the basics
Analog transmitters easily send process measurements from different areas in a plant to a central PLC where process control decisions can be made based on transmitter feedback. Analog transmitters are great cost-saving alternatives to single-point controllers. In situations where multiple sensing locations are required, single point controllers’ costs can add up quickly.

Process Puzzler
We’re expanding our old oil refinery. Part of the expansion includes replacing our underground settling tanks. Unfortunately, we’re not sure where all the flows are coming from; generations of engineers added to the network, making analysis of this complex of underground piping almost impossible. Can you suggest any methodology for identifying these sources? In addition, laboratory tests show that we have naphthalenes in our settling tanks, which confounds our efforts to reduce the size of the new settling tank. This tank will replace one of the larger, older, corroded tanks. How can we reduce the size of this new tank and handle naphthalenes?
