SCUL-SENSE Two-Wire Optic Sensor

Brand: Scully Signal Company
Scully two-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-15 series loading rack control monitors. The sensors can also be used with the Scully IntelliCheck® II 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 two-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
  • Maximum safety with Dynacheck - Automatic and continuous self-checking circuitry when used with Scully electronic rack and vehicle onboard monitoring systems
  • Scully’s field-proven electro-optics technology
  • Wide Temperature Range. Adjustable Sensing Level
  • Instant-On™ - Instant permissive signal. No warmup time required
  • Quick purging of liquid  - ”fast” repermit as product level drops below the sensing point
  • Fully compatible with all Scully thermistor controllers
  • FM approvals for Class I, Division 1, Groups C and D hazardous locations in the US and Canada
  • Meets requirements of API Recommended Practice RP-1004
