PRODUCTS EDITOR'S CHOICE MONITORING THE SEDIMENTATION PROCESS


KROHNE has re-engineered its OPTISENS OAM 2080 sludge blanket measuring system to extend its area of application to sedimentation processes. The result, the OPTISYS SLM 2100, allows for reliable tracking of sedimentation layers in industrial and municipal applications, as well as sludge blanket measurement in clarifiers and sludge thickeners in sewage treatment plants. Unlike ultrasonic-based sludge level


meters, the optical measuring principle used is not subject to echo returns from walls or separating zones as well as signal damping by fluff or floating sludge. The new instrument offers three measuring modes: measurement of sedimentation profile, two-zone monitoring and zone- tracking. For sedimentation profile measurement, the system directly measures the suspended solids concentration at all heights as the sensor travels through all layers of the medium. The two-zone monitoring feature enables users to monitor the heights of two predefined concentrations, e.g. fluff and sludge. It can be used


to prevent sludge washout into the next stage. For continuous level measurement of a predefined concentration (zone-tracking) the optical sensor moves within the medium until it detects the concentration and follows or tracks this zone continuously. This can be used, for example, to monitor the change of the sludge blanket level when de-pumping the sludge. The integrated signal converter of the OPTISYS SLM 2100 is the MAC 100 multiparameter converter for analytical measuring devices. Additional features include two 4…20mA outputs that communicate height and concentration according to the selected measuring mode; and both the sensor and housing


are made of stainless steel. The protection rating IP54 housing has a built-in fan and a heater for cold conditions.

Maxim Integrated Products’ lithium-ion (Li+) battery monitor is being used by Nissan Motor Co. for the Nissan Pathfinder Hybrid, a sport utility vehicle for the North American market. The Li+ battery monitor provides self-diagnostics and robust daisy-chained data communications that easily handle the high-voltage requirements of the automotive industry. According to the company, its highly integrated solution enables a smaller, lighter weight, and high-performance Li+ battery system in the hybrid. Using Hitachi’s battery system with the Li+ battery monitor IC, the Pathfinder Hybrid is said

to achieve greater driving range and improves the overall safety of the battery system. “I am pleased that Nissan selected our


cell-monitoring IC for its Pathfinder Hybrid,” commented Kent Robinett, managing director, automotive marketing for Maxim Integrated. “Maxim is advancing into a next-generation EV/HEV powertrain system, and we will continue to develop highly integrated products for this market.”

TRANSPARENT OBJECT SENSOR DETECTS BOTTLES, TRAYS AND FILM IN THE FOOD AND BEV INDUSTRY


New from Omron is the E3S-DB, a transparent-object sensor specifically designed for the food and beverage industry which is said to offer better detection of objects such as glass bottles, PET bottles, transparent trays or packaging film. To enable high-precision detection and positioning on conveyors where the smallest of gaps between


bottles exists, the device is also available in narrow-beam models with a convergent beam that has a focused spot size of just 2mm at a distance of 200mm. The E3S-DB sensors apply a technique known as P-Opaquing, which offers increased detection


At just 4.5 x 2.5 x 1cm, Pyreos has released what it claims is the world’s smallest spectrometer demonstration vehicle. This, it explains, will enable application specific focus for both consumers and customers. The unit features the company’s Mid IR sensor technology, offering low power array sensor solutions. Later this year, the company expects to


release ‘vastly smaller’ spectrometers with extremely low power consumption targeted at the wearable market.

stability through special polarising filters for PET objects. A further advanced feature also automatically compensates for light-level changes caused by ambient conditions or contamination. Additional features include an optical system that enables sensing with low hysteresis and high dynamic range – it can, for example, detect just 3% light-intensity attenuation at a distance of up to 4m. Its advanced optical system also increases stability performance by completely cutting off even the smallest amounts of stray light that might interfere with glass bottle detection. Of additional benefit, setting up the instrument is quick and easy thanks to Omron’s ‘Smart Teach’ function; and information about the operational threshold of the sensor is always clearly visible. The operator can also easily copy the setting from one sensor to another.

CALIBRATING ACCELEROMETERS


A compact, portable vibration exciter, designed to calibrate the sensitivity of accelerometers in both laboratory and field environments, has been launched by Kistler. The Type 8921B reference shaker provides an accurate, controlled vibration level to verify the sensitivity of accelerometers weighing up to 600g, or a complete measuring system, traceable to a national standard. The internal control and excitation


system provides a constant, precise frequency whilst a closed loop control maintains constant amplitude independent of the mass of the test article. Should the test article exceed the capacity of the shaker, the unit provides an audible and visual warning. The device also provides an accurate way of testing the integrity of a vibration measurement system from end-to-end. Its rechargeable battery can power the shaker for up to five hours.
