DATA SHEET DREXELBROOKIntelliPoint RF™ Series Two-Wire Point Level Switch • No calibration or setpoint adjustments. • Ignores changes in dielectric or conductivity. • Automatically recognizes and ignores coatings to prevent false alarms. • Continuous self-test monitors circuits and sensing elements for faults. • Detects the absence or presence of liquids, slurries, interfaces and granulars. • 8mA (Alarm) 16mA (Normal) or 8mA (Normal) and 16 mA (Alarm) • Unlike many technologies, electronics can be remote mounted to a convenient or safe location The only RF switch you won't calibrate. Simply install the IntelliPoint RF Series into the tank and apply power...that's it! Unlike other RF or capacitance systems that require calibration via setpoint potentiometers, jumpers, magnets, or pushbuttons, the IntelliPoint RF Series reliably detects the absence or presence of material without any adjustments. The IntelliPoint RF Series software continuously monitors the application for changes in composition, dielectric or conductivity, and maintains a repeatable trip point on the probe. Other RF and capacitance systems require calibration adjustments when the process material is changed. Since the IntelliPoint RF Series recognizes changes in material, it is ideal for non-dedicated tanks that are used for a wide variety of products. Automatic and manual test functions ensure proper system operation. An AutoVerify™ self-check circuit continuously monitors that the complete system is functioning properly. The Manual Certify not only checks the function of the system, but also checks the AutoVerify self-test circuits to make sure that they are also working properly. New dual compartment housing separates the customer wiring from the sensing element and operating circuits. The encapsulated power supply/ terminal block design eliminates the possibility of damage caused by moisture in the conduit.
