In its EXspect 271 backscattering sensor, the company EXNER is launching a compact measuring device for reliable and economical turbidity measurement. One major benefit of the new sensor is in the spherical design of its optical measurement system. This minimises the attachment of air bubbles and the build-up of deposits. The focussing of the beam due to the sapphire lens allows for a measurement right on the barrier layer of the medium, meaning only the reflection is measured, and not the proportion of the light beam absorbed. Both the attachment of all kinds of things to the measurement system and the measurement of absorbed proportions are drawbacks on the current market.
The measurement takes place in the near-infrared region (NIR) at a wavelength of 880 nm, which allows for colour-neutral measurement. The LED light source being used guarantees a long-lasting and stable signal. The stainless-steel case of the EXspect 271 has a hygienic design and is suitable for CIP/SIP. As another special feature, NIST-traceable reference standards can be obtained for calibrating or checking the sensors in the field.
Due to its hygienic and robust design, the EXspect 271 sensor is suitable not only for many applications in the food and drinks industries, but also for diverse applications in the processing industry. This includes, for example, yeast recovery, phase separation, purification processes in dairy plants, and the measurement of cellulose concentrations.
EXNER Process Equipment GmbH, based in Ettlingen, is in the middle of the Karlsruhe technology region. The medium-sized company has operated as an international provider of high-quality process holders for pH measurement and optical sensors for the determination of cell growth and turbidity for 15 years. The owner-run company is characterised in particular by its accurate and long-lasting products, its agile and flexible way of doing things, and customer-specific solutions. The products developed and produced by the ISO9000-certified business offer the highest degree of variability and can therefore be configured to meet almost any requirement. Customers from the chemical industry, in the bio and food technology sectors, and the pharmaceutical industry all benefit from their consulting and support services, as well as their innovative research and development division. Thanks to the combination of their expertise gained over many years and the use of new technologies, their products are being continuously developed and optimised for each area of application. So, the processes become safer, more efficient, and more accurate. In addition, EXNER products are being supplied by distribution partners and OEM customers all over the world.
