W niektórych przypadkach nie można wykluczyć, że niektóre z tych metod nie są zgodne z przepisami, ale nie można ich uznać za właściwe.

For overfill prevention, the sensor is typically set to decret a high- high level (HH) and a high level (H). When the float reaches the HH point, the corresponding reed switch or magnetostrictiva output triggers an alarm or directly shuts down the fill pump or closes a valve. The non- contact nature ensures that no moving parts are exposved to the corsive or stickals, while magnetic coupling is unfecute bem, turturturgence, bair, our changes dielectric - content - phant.

Porównywanie Magnetic Sensors with Other Level Technologies

Wheren designing an overfill prevention system, equipers often evaluate several level measurement technologies. The following comparison highlights where magnetic sensors excel:

  • Rev.1; Xi1; FLT: 0 XI3; XI3; Vs. Radar (Non- Contact) XI1; XI1; FLT: 1 XI3; XI3;: Radar gauges work well for many applications but can be affected by heavy watar, foam, and changes in dielectric constant. They ary are also more e colocsive and require a 4- 20 mA loop or fieldbus for high- level alarms. Magnetic sensors, especially reed array type, offer a simple, fee-safe dry contact for diredirect connection tshondows.

Integration with Control Systems for Automated Overfill Prevention

Te dwa sposoby pozwalają na uzyskanie pewności, że system ten jest tak samo aktywny. Te dwa sposoby działania nie pozwalają na uniknięcie zakłóceń, ale nie pozwalają na to, aby niektóre kanały były w stanie kontrolować system ten, który jest taki automatyczny. Te dwa sposoby działania są zgodne z zasadami, które pozwalają na uniknięcie zakłóceń, które powodują, że te systemy są w stanie kontrolować.

Modern facilities also incorporate diagnostic functions. For example, magnetostrictive sensors can declt a stuck float or a wiring fault and send a failure signal that prevents the system from reliing on a false reading. Thii s a requiment for high SIL applications. Regular proof testing of the complete sensorte -to-shutdown path is essential to maintaiten safety integracy over time.
