Wood chip or wood pellet heating systems are modern CO2-neutral biomass heating systems for both private and large industrial plants. As the volume consumption is relatively large compared to liquid fuels, the knowledge of the current level is particularly important. For large industrial heaters the feed quantity has to be controlled and thus measured as well.

Conventional simple level gauges are often overstretched because of the dirty and dusty environment in a tank or on a chip-conveyor belt. Whereas ultrasonic sensors measure reliably even in dusty air and with polluted membrane. Wood pellets are pressed sawdust with no additives. They are particularly suitable for home heating. Wood chips are used mainly in agriculture and industry, where wood residues are available almost for free.

Best suited ultrasonic sensors for this application are the UFA or the UN Series.

Fleece is a nonwoven fabric of individual fibers. It consists of loose fibers, which are not linked. The strength of a fleece is based only on the fiber's own adhesion, but it can be influenced by further processing. To be able to handle and use the fleece, it must be reinforced, for which various methods can be applied. Nonwoven fabrics are used for example in various hygiene articles.

To control the desired compression of the material in production one can measure its sound permeability. The denser the material, the more impermeable it is for sound. With the ultrasonic fork sensors type UBA-A of WayCon good and reproducible results are achieved. The sensor output is directly an analogue signal which is a function of the accoustic permeability of the fabric which passes between the transmitter and receiver of the sensor. The sensor is very fast, thus it works even with fast moving material webs. Applications...

The new DK830S series from Magnescale

The new DK803S gauge series combines high accuracy and robustness with slim and compact design. This new gauge provides a measuring range of 30mm which is a perfect addition to the current models with 2mm, 5mm and 12mm stroke. Due to the high accuracy of 1,3μm (p-p) over the entire measuring stroke of 30mm, this system is suitable for the measurement of precision parts with very fine tolerances.

With a max. response speed of 250m/min at 0,5μm resolution and 80m/min at 0,1μm resolution, this system is a perfect fit for applications with very short cycle times.  Gauges

UBA-A ultrasonic fork sensors used in production of photovoltaic foils

The new UBA-A sensors  are used in the production of novel flexible photovoltaic foils. Existing silicon based photovoltaic cells are deposited on glass, which is heavy and fragile. The new partially transparent polyimide films are subjected to vacuum coating processes and rolled up at the end. The low weight and mechanical flexibility opens completely new fields of solar electric power generation. Application

WayCon Positionsmesstechnik has submitted a suggestion to BP for the oil well incident in the Gulf of Mexico.

Application: Pipe connection to an undefined natural opening or pipe system e.g. blowout preventer BOP, with escaping liquid/oil under high pressure.

Since the 1st of April 2010 the new Magnescale Co., Ltd has taken over the measuring business from Sony Manufacturing System Corp. In Europe the newly established company Magnescale Europe GmbH which is a subsidary company of Magnescale Co., Ltd will take care of the sales & marketing activities for the MS buisness.

Within the next 6 month, the logo on the products, manuals and packages for Lasercale, Magnescale and Digital Gauge from Sony will be replaced to the brandname “Magnescale“. There will be no changes in performance, specifications and quality of the products. In the transfer phase of 2010, it might be possible that the customers receive products with the name Sony and Magnescale.

The series of magnetostrictive transducers with SSI interface have been renewed, increasing performance to satisfy market demands. The electronics has been completely redesigned to improve the linearity and communication of all models. Among the principal innovations is the new “internal linearization” option, which provides linearity up to 4 times higher than the standard version by performing linearity compensation in the electronics.

The entire SSI series has been given new electronics compatible with EMC standards and is more resistant to power surges. The reduction in overall noise improves transducer communication. In addition, the communication structure has been aligned in all versions (with and without the oversampling algorithm), making the entire series more compatible with SSI sensors made by other companies.

With regard to technical specifications, maximum working temperature has been raised to 90°C and current input has been halved, dropping to 50 mA, the lowest level on the market for this product!

The new edge sensors type UBA with ultrasonic through beam sensors. New software algorhythms and a unique ultrasonic transducer material allow an accuracy and temperature stability so far only realized with optical systems. But the ultrasonic fork barrier is much less sensitive to dirt and dust compared to optical sensors. Further more transparent materials such as foils can be perfectly handled. The so called plane change error has been minimized to almost zero. Together with the high sampling speed of the sensor this means that fast moving and thus fluttering webs are well aligned.

The sensor can ideally be adjusted to the actual air conditions by the help of the teach-in function. Furthermore acoustically transparent materials such as textiles can be measured. With teach-in the signal output can be defined at fully closed as well as at fully open fork. In addition, the output signal can also be inverted via teach-in. The new sensors can be teached by push buttons or through the connector. 3 LED indicate the actual position in 5 steps.

An ancient burial monument ca. 300 BC, was unearthed 100 years ago in the near of Thessaloniki, Macedonia, Greece. Over the years the monumnet is becoming unstable due to ground erosion. A solution to stabilize the monument was needed. The responsible Division of the Ministry of Culture appointed the company „Neotek“ a greek distributor of WayCon Positionsmesstechnik GmbH in Germany to find a solution.

To accomplish this project, an accurat measurement system was necessary to collect the relevant data. Various draw wire transducers from the series SX are connected to a self-standing data logger and a battery box. Power is conserved by a timing switch. The Waycon displacement transducers monitor structural deformations and convergences. Readings are taken every 6 hours.  more pictures, slideshow

Measure distances with millimeter accuracy. Define positions. Measure fill levels.Register motion processes. The LLD Series from is a opto-electronic distance meter designed for industrial applications. Measurements up to 150 m are performed precisely, fast and in a non-contact fashion using the comparative phase shift method. Equipped with interface options such as Profibus DP, SSI, RS232 or RS422 as well as selectable switching and analog outputs, the sensors can easily be integrated into any industrial infrastructure including fieldbus-driven process controllers.

The compact and robust design shape combines with low power consumption, and the possibility to set specific de-vice parameters warrants flexibility in use. Optional heating enables indoor and outdoor operation at low temperatures.

The benefits are phase comparison by distances up to 150 m, distances can be reliably determined in a noncontact procedure that requires no reflector, easily perceivable measuring beam is provided for pinpoint alignment of the sensor.
