Scully five-wire optic sensors are designed
for liquid petroleum product overfill prevention and point level detection.
The new ScuL-Senseâ„¢ design is API
compliant and eliminates temperature
stresses, dramatically improving reliability
across a wide temperature range.
They are designed to be used with Scully
Intellitrol® and ST-35 series loading rack
control monitors. There is no waiting for
the control monitors’ permit light to go on because the sensor requires no warm up time. The sensors can also be used with Scully Intellicheck® II or Scully Load Anywhere ® monitor.
The five-wire optic sensor incorporates
Scully’ s unique and exclusive Dynacheck
circuitry when connected to Scully monitoring equipment. To ensure that the system will always detect an overfill condition, the controller uses pulsed signals which continuously check the entire system operation, including sensors, wiring, connectors and itself. If a sensor comes in contact with liquid, or in the unlikely event of a system fault, the pulsed signals cease and the controller automatically signals for
immediate shutdown of the loading operation.
No operator involvement is needed.
Shutdown is accomplished by controlling
pumps or valves.
