SCUL-SENSE Five-Wire Optic Sensor

Brand: Scully Signal Company
Request Information
Scully five-wire optic sensors are purpose-built for liquid petroleum product overfill prevention and point level detection. 

They are designed to be used with the Scully Intellitrol® and ST-35 series loading rack control monitors. The sensors can also be used with the Scully IntelliCheck® II Monitor or Scully Load Anywhere® Truck Monitor. There is no waiting for the control monitors’ permit light to go on because the sensor requires no warm up time. 

Overfill prevention applications include road tankers, rail cars and storage tanks. The five-wire optic sensor is a critical component in Scully’s unique and patented Dynacheck circuit design. When used in conjunction with Scully electronic monitoring equipment, our overfill protection sensor will provide consistent failsafe monitoring. 

By constantly checking a “closed loop” pulsing signal across the entire system, Scully ensures a safe and reliable loading operation. If rising fuel contacts the sensor, this signal is interrupted and the controlling pumps and valves are shutdown. No operator involvement is needed to end the loading operation.
Features
  • Ensures a safe and reliable loading operation by constantly checking a “closed loop” pulsing signal across the entire system 
  • Requires no warm-up time
  • Eliminates operator involvement to end the loading operation - pumps and valves are automatically shut down if rising fuel contacts the sensor
  • Can be wired in series for compatibility with Scully Load Anywhere® or IntelliCheck®3 onboard monitors
