Safety IntelliPoint RF Switch
Mar 16, 2009
Safety IntelliPoint RF SwitchThe Safety IntelliPoint RF Switch is the first RF Admittance device with SIL certification. The safety switch was developed specifically for above ground bulk storage facilities, such as tank farms, to meet the American Petroleum Instituteís 2350 Recommended Practice (RP) for overfill and spill protection. The safety switch is derived from Drexelbrookís IntelliPoint Series of RF Admittance point level switchesóthe industryís first RF point level switch that does not require users to calibrate or adjust set points. The IntelliPoint is able to detect the presence or absence of material without calibration. Users need only to install the switch in a tank and apply the power. The IntelliPointís software continuously monitors the application for changes in composition, dielectric or conductivity and maintains a repeatable trip point on the probe. The IntelliPoint requires significantly less maintenance than traditional mechanical switches, and its Cote-Shield technology ignores errors caused by coating build up on the sensing element that often results in false alarms. The safety switch is available in a two-wire configuration. The system is housed in a dual compartment enclosure that separates the customer wiring and power supply from the sensing element and operating circuits. The encapsulated power supply/terminal block design also eliminates the possibility of damage caused by moisture in the conduit.
