Intellipoint SIL2 Safety Switch Combines Field-Proven Performance with Safety Conformance

In-Line Device Features Auto Calibration and Maintenance-Free Operation

HORSHAM, PA - The IntelliPoint SXRNT Series RF Admittance Point Level Switch from AMETEK Drexelbrook. conforms to IEC61508-2, Sec. 7,4,3,1 1999 FMEDA standards for Safety Integrity Instrumentation (SIL) as evaluated by Exida. The SXRNT Series is suitable for SIL1 and SIL2 installations and for SIL3 installations when installed as two redundant switches.

The International Electrotechnical Commission (IEC) developed the IEC 61508-2 standard to assist companies in implementing Safety Related Systems. It specifies the techniques and measures recommended to achieve the required Safety Integrity Level. There are four Safety Integrity Levels ranging from 1(lowest) to 4 (highest) that are based on the potential risk and number of opportunities for failure.

AMETEK Drexelbrook is the technology leader in level measurement with the industry's most complete offering of level measurement solutions. Its advancements in No-Cal technology resulted in the initial development of the IntelliPoint RF Series-the first RF point level switch that doesn't require users to calibrate or adjust set points. IntelliPoint's Auto-Calibration feature allows it to detect the presence or absence of a material without adjustment, making the device virtually maintenance free.

The IntelliPoint's 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 changes. Since the IntelliPoint recognizes changes in material, it is ideal for non-dedicated tanks that are used for a variety of products.

RF Admittance is the most versatile technology for point level measurement. The Intellipoint will accurately measure liquids, solids and slurry materials. It can also be used to detect the interface between any insulating and conductive liquid. Sensors are available in a wide selection of materials for compatibility and environments. Temperatures ranges from cryogenic to 2000 degrees Fahrenheit and pressures from vacuum to 10,000psi are attainable.

Specialty sensors are available with flexible probes for applications where a long sensor is required. The IntelliPoint also allows for the electronic unit to be mounted in a remote location away from an inhospitable environment where the sensor is located.

AMETEK Drexelbrook is a level measurement industry pioneer with over 40 years of experience. It has provided level measurement solutions to virtually every industry across a broad spectrum of applications. AMETEK Drexelbrook is a unit of AMETEK, Inc., a leading global manufacturer of electronic instruments and electric motors with annualized sales of more than $1.2 billion.
