Fbffulfff FDJ03 Fluid/14por Leak Detection Systan. <br /> Liquid Hydrocarbon Detection <br /> Major features: <br /> • Interfaces with present FD-system-RA probes and new <br /> -RA vapor probes <br /> • Safe for all Class I,Division 1,Group D <br /> hazardous locations _ <br /> • Can monitor up to 15 probes with one control unit <br /> • Liquid Crystal Display(LCD)displays probe number <br /> and status <br /> • Keyboard entry of alarm conditions and relay closures <br /> • LCD visual alarm displays <br /> • Audible alarm—continuous for alarm,pulsing for error <br /> • RS232C data output ar <br /> • Microprocessor-based system <br /> • Permanent nonvolatile memory backup ; <br /> • Factory selectable voltages—120 VAC,240 VAC Factory <br /> Available,50/60 Hz t <br /> • Internal circuit breaker <br /> _ f <br /> Mode of operation: <br /> System works on the principles of conduction(liquids)and <br /> adsorption(vapors).Typical water is a conductive,or polar <br /> fluid. Hydrocarbons are non-conductive,or non-polar sub- <br /> stances.The system circuitry can differentiate between <br /> polar and non-polar fluids and provide the appropriate <br /> alarms and contact closures when a non-polar fluid is <br /> detected. Ambient 0°C to +50°C. <br /> Vapors are detected by a cold sensor that electrically temperature <br /> measures the force of adsorption and translates it to a resis- <br /> tive change.When a predetermined vapor threshold is ex- Economical probes for any application: <br /> ceeded,the system again provides the appropriate alarms. • Ground water probes • Vapor detect probes <br /> Installation requirements: • Surface water probes •Reservoir probes <br /> Sensor NEC Class I,Division 1,Group D • Double-wall tank probes • Piping probes <br /> hazardous locations. <br /> Cable length 1000 feet maximum to any probe.
