Pacific Sensor Technologies recently supplied a Bin Master Smart Bob inventory measurement system and PRO-Series point level capacitance probes to Power Station for installation on
18 of their coal bunkers.

The Smart Bob inventory measurement system was installed to let operators know the exact level of the coal in each of the 18 bunkers. It was chosen because it provides a simple interface between the Smart Bob remotes and a programmable logic controller located in the coal handling control room.

This programmable logic controller initiates a measurement by providing a dry contact closure to a Bin Master remote start unit. It can then retrieve the bunker level measurement from an analog 4-20 mA current loop output from the remote start unit, which is then displayed in the control room thanks to the human machine interface software package.

PRO III X point level capacitance probes with flexible extensions were also installed on top of the bunkers to provide a high and high/high signal.
