•_ MODEL 510 <br /> BEAUDREAU DISCRIMINATING SENSOR <br /> BEAUDREAU ELECTRONICS INC. <br /> The Model 510 Discriminating Sensor is <br /> designed to provide gasoline dispenser <br /> sumps or submersible turbine sumps with <br /> fully discriminating leak detection. The <br /> sensor uses a polymer strip to detect fuel <br /> at any level along its length and has an <br /> optical sensor mounted at the top for <br /> sensing high level accumulation. It will <br /> only alarm if it detects fuel or if water in <br /> the sump reaches the high-water sensor — <br /> it is not affected by background vapors in <br /> the sump. Upon alarming, the sensor will <br /> shat off the dispenser or turbine power <br /> until the fuel is removed. Once the sensor <br /> has been exposed to fuel, the polymer <br /> strip inside the sensor housing can be <br /> replaced with a new strip to prevent future <br /> false alarms. The strips are inexpensive <br /> and are easy to replace. For more <br /> information, contact Beaudreau Customer <br /> Service at 1-800-739-4435. <br /> SENSOR OPERATION <br /> Unlike other leak detection sensors, all Beaudreau sensors are designed to connect directly to the <br /> dispenser or STP electrical junction box, eliminating the need for installing new conduit and pulling new <br /> wires. This allows sites with existing secondary containment to be easily retrofitted with leak detection. <br /> The 510 Discriminating Sensor can be operated by either the Beaudreau 404-4 Controller (shown above) <br /> or the new 500 Series Controller. While both controllers are designed to shut off power to the dispenser <br /> 1 or turbine when the sensor alarms, the 500 Series Controller can also send fuel or water alarm signals to <br /> an inside monitoring system across existing electrical wiring. <br /> SPECIFICATIONS <br /> Part No. Sensor: 511) Controller: 401-4 or 500 tteplaeemerrt Strip: 510 S <br /> Dimensions Sensor Ileighl: 13.00" (length of detection 11.110 ').
