Hemco provides the latest in Ground Verification Monitors, some of which visually confirm a ground connection between the transport and the loading terminal, giving you peace of mind and more importantly, safety. We provide Ground Verification Monitors that use technology that is compatible with transport ground systems used today. One monitor has a 5 amperage, 240 volt relay output for control of terminal automation systems (T.A.S.) or pump control devices when used as a stand-alone system. We distribute a monitor that is equipped with green and red lamps for visual status indication. When a proper ground signal is present the green lamp will light and a permissive signal will allow the load rack to be operational. If the ground is lost, the red lamp will come on indicating a non-permissive state and shut down the loading operation.
