Safety IntelliPoint RF™ Series
Two-Wire, Point Level, SIL Conforming Safety Switch
One of the Drexelbrook RF Point Level
Switches You Won't Have to Calibrate
The 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.
Self-Test Feature
Automatic and Local or Remote Manual test functions
ensure proper system operation.
Intelligent Electronics
•t Meets Title 49 Part 195 DOT and API 2350
regulations.
•t For use in safety related systems with
requirements for functional safety for SIL2 (SIL
3 with Redundant Switch) In accordance to
IEC61508-2, Sec. 7.4.3.1 1999 (Conforms to
SIL, FMEDA Requirements - Exida)
•t No calibration or setpoint adjustments.
•t Automatically recognizes and ignores coatings
to prevent false alarms.
•t Continuous self-test monitors circuits and
sensing elements for faults.
•t Remote or Integral Electronics
Diverse Applications
• Liquids, Slurries, Interfaces and Granulars.
Dual Compartment Housing
The 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.
Auto Verify™
Each IntelliPoint™ is supplied with a continuous
self-test feature that constantly monitors the integrity
of not just the electronics, but the sensing element
and interconnecting cable. If a fault is detected,
the IntelliPoint Auto Verify™ feature alerts plant
personnel.
Manual Certify™
The IntelliPoint™ provides a method to manually test
the entire system without removing the sensor from
the tank. The Manual Certify Test checks that the
Auto Verify circuits are operating and confirms the
probe and cables are properly connected. The Manual
Certify also allows the IntelliPoint™ electronics to
sense changes in the probe that simulate contact
with the media or a floating roof. This provides the
user with a method to insure working performance
without having to climb the tank. At the completion
of the Certify test routine, the output is momentarily
held in the alarm state so personnel can confirm that
the control circuits connected to the Final Control
Element are functioning properly.
