RF Admittance Level Measurement RXL Series, IntelliPoint-1

A Leader In Level Measurement Solutions IntelliPoint RF Series Point Level Switch One of the Drexelbrook RF Point Level Switches You Won't Have to 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 the IntelliPoint RF Series recognizes changes in material, it is ideal for non-dedicated tanks that are used for a wide variety of products. Universal Power Supply Intelligent Electronics • 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. • Universal power supply automatically detects input power source. Diverse Applications • Detects the absence or presence of liquids, slurries, interfaces and granulars. • (2) SPDT relays; relay#2 can be configured as an alarm or fault. Dual Compartment Housing • Power Supply is isolated from intrinsically-safe sensing element and circuit board. Remote or Integral Electronics • Unlike many technologies, electronics can be remote mounted to a convenient or safe location The IntelliPoint electronics use a universal power supply module that can be powered from a 85 to 250 Vac or 21 to 100 Vdc supply without moving jumpers. Self-Test Feature Automatic and manual test functions ensure proper system operation. An AutoVerify™ selfcheck 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. Dual Compartment Housing New dual compartment housing separates the customer wiring and power supply 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.
