Thanks to hacksaw and 209larry for your observations. I am not familiar with the test resistor/test RTD concept. If you could provide additional information I would appreciate it. After thinking about this all weekend, I am wondering if the extension wire is acting like one long RTD since it is...
Thanks to TD2K and hacksaw for your input. We have checked the RTDs on the Benzene Column (2-wire 100 ohm platinum) and they both read the same resistance; therefore the same temperature. This translates to a delta T of 0 across the fifth and fifteenth trays of said tower. From my own...
We recently ran temporary extension wire for RTD sensors on our Benzene and Toluene columns. The electricians used crimp-on connectors to terminate the connections. On each Column there is a set of RTDs to measure temperature differential across the appropriate trays. Since this unhappy...
I am involved with the operation of a Benzene Column being fed with extract from a Sulfolane Unit. Even though this unit is 40 years old, all the instrumentation is working (with some updates). The operators refuse to run the Differential Temperature controller in the automatic mode, because...
