POINT LEVEL DETECTION LEVEL Tutti i dati ed i contenuti di questa scheda sono di proprieta esclusiva di Riels Instruments Field of application CONTACT RLBFI is designed for level detection in tanks and dry-run protection of pumps by empty pipe monitoring. It detects liquid, pasty or oily media, but also solid-bulk materials like flour or plastic granulate. The CONTACT RLBFI is capable of media differentiation by distinguishing the specifc properties, such as oil, water foam and liquid. Reliable performance is assured in any mounting position (from top, bottom or side). Depending on the desired process connection, different mounting options are available. Corresponding mounting aids and adaptors for conventional process connections are available as an accessory Two switching outputs are available with dedicated switching windows. The switching function is programmable as PNP NPN or digital (pushpull) polarity as well as the switching logic like Normally Open (NO), Normally Closed (NC) or inverted. CONTACT RBFI in its default confguration covers a major part of potential applications. Where customer-specifc confguration is required because of demanding media (e. g. foamy or adhering), qTeach, remote teach, IO-Link or the FlexProgrammer allows for easy optimation of the switching windows. The measured data can be visualized on a PC for further parameter adjustment, for example time constant of a damping function and inverted switching output logic. Measuring principle An electrode integrated into the sensor tip forms a capacitor with the environment. The medium determines the capacity value depending on its dielectric constant (DC values). A resonant circuit occurs together with a coil in the sensor electronics. Depending on the resonance frequency measured and the programmable trigger threshold, the switch signal is activated. The EHEDG certifcate is only valid in connection with the appropriate installation parts. These are marked with the "EHEDG Certifed" logo. The 3-A Sanitary Standard requirements are only met with the appropriate installation parts. These are marked with the 3-A logo. Approved for explosion hazard areas when installed as specifed. Approved by Underwriter Laboratories (UL) for use in the USA and Canada as an industrial control device. Highlights of the product • Detection of liquids, bulk solids and powders. One sensor for all applications. • Compact immersion length • Capable of differentiation between foam and liquid • Insensitive to adherent or sticky media • Status indication via multicolour LED • Compact stainless steel housing, up to IP69K protection • Teach-in on-site or remote via control cable • Two switching outputs with dedicated switching windows • Configuration and IO-Link interface Construction and function 1. Sensor tip 2. LED 3. Connection with M12 plug • Overfll protection • Run-dry protection The sensor can be mounted on any point in the vessel. A sensor mounted at the top of the vessel (1) ensures against overfilling. Sensors attached further down detect a maximum (2) or minimum (3) limit level. A sensor attached at the bottom or on the outfeed pipe (4) can protect a connected pump against dry running.
