Rosemount Temperature Measuring Unit


The Rosemount Temperature Measuring Unit measures the temperature of the cargo and vapor in the tank. It can be measured over the tank height with both three and four wire connections. The temperature data is processed by the Tank Gauge Electronics (TGE) and sent to the Supply and Communications Unit (SCU). The temperature can be monitored from the Workstation, the Tank Gauge Display, Channel Display Unit or on the Portable Readout System.
