Non-contact detection of bulk solids

December 2003 Sensors & Transducers

The detection of bulk solids of all kinds in mining, food and beverage and storage applications just got that bit easier with the release of the microwave barrier Soliwave M FQR 50/FDR 50 from instrumentation and control specialist, Endress+Hauser.

The newly launched Soliwave M uses a contact-free procedure for limit detection of bulk solids. It can be installed in containers, conduits and shafts, or on free-fall shafts. Soliwave M can also take a measurement through non-metallic container materials from the outside and can operate in temperatures up to 70°C and pressures up to 400 kPa.

The radar device is suitable as a level limit switch for controlling and counting all types of bulk solids, including wood chips, wood dust or flour, plaster, cement and ash, paper or cardboard shred, gravel and sand, dried powders and bags and boxes.

The option of a flush front for contact-free assembly is available. For different media the signal strength, which can be read off the receiver's LED display, can be adjusted to alter the sensitivity of the measuring device. A robust mechanical design ensures no wear and tear, long serviceable life, as well as maintenance free operation. Assembly is simple, using a standard R11/2 thread screw. The bulk solid level-measuring device conforms to ATEX 1/2 D.

Operation is simple: the FQR 50 emitter projects the signal via an integrated horn antenna. The FDR receiver, normally directly opposite, detects the signal and forwards a switching signal to the Nivotester FTR evaluator. Alarm and control devices may be connected to these relay outputs. If, for construction reasons, a direct confrontation of the emitter and the receiver is not possible, the microwave beam can be redirected via a flat metal mirror. By using reflectors, the range of the microwave barrier (normally between 8 m and 20 m) is reduced by around 10% per reflector.
