EDITOR ’ S CHOICE ifm ’ s new longer-tip conductivity sensors simplify CIP

Particularly suited for use in CIP ( cleaning-in-place ) applications in the food and beverage industries , the new LDL201 conductivity sensors from ifm electronic have a 77mm long sensing tip which makes them versatile and easy to install in a variety of hygienic process connections . In addition , the tip features solid PEEK construction which virtually eliminates the risk of breakage even if the sensor is subjected to high levels of stress .
Typical applications for the new LDL201 sensors include monitoring / control of cleaning agents , checking rinse water for residues and product validation . Since the sensors allow improved process control to be achieved , they typically enable users to cut costs by reducing energy usage during CIP cycles , along with the consumption of water and cleaning agents .
LDL201 sensors have a conductivity measuring range of 100 µ S / cm to 1000 mS / cm and feature an integrated temperature sensor . They have a continuous operating temperature of -25 to + 100 º C and a maximum of 150 º C < 1 hr . They are provided with an IO-Link interface which provides loss- and error-free transmission of measured conductivity and temperature values . IO-Link also allows easy parameterisation , which not only aids initial set up but also makes it quick and easy to adjust settings to accommodate recipe changes .
With food-grade material used for all parts exposed to the media in which they are being used , ifm ’ s new conductivity sensors meet EHEDG , FDA and 3-A standards . They are available for fast delivery and are complemented by a wide range of accessories . These include welding adapters , clamps , hygienic pipe fittings and pre-terminated connecting cables .

Demand grows for improved water treatment systems

Stringent discharge rules for trade effluents are fuelling enquiries into the benefits of the latest wastewater processing technology , says Axium Process .
The filtration specialist has seen a rise in demand for customised membrane systems as environmental responsibility , operational costs , and discharge limitations put increasing pressure on companies to find improved solutions for trade effluents .
Derek Davies , Business Development Director at Axium Process , said “ A growing number of industrial companies need to balance their discharge consent against increased levels of production and spikes in output linked to manufacturing processes . Failure to do so can result in hefty fines , snap inspections , and reputational damage .
“ Even similar industries have very different filtration requirements , so the ideal solution is a purpose-designed treatment process for each application . To identify and optimise the best solution , our engineers first conduct investigative pilot trials on the feed material either at our test facility in Swansea or the manufacturer ’ s premises . The trial results will clearly identify the main requirements for the project and associated benefits .”
Advances in effluent processing techniques mean that crossflow membrane filtration can filter raw effluent and recover high quality water . It allows highly customised solutions to be developed that can meet ambitious sustainability goals .
As it is a physical process no chemicals are required to separate suspended or dissolved materials . The technology has the potential to significantly reduce effluent disposal costs while recovering up to 95 per cent clean reusable water .
Water recycling systems from Axium Process can be used in almost any industry , including pharmaceutical , food , drink , textiles , chemical and automotive . They can also be used to complement other waste treatment processes such as anaerobic digestion . www . axiumprocess . com
