Preventing a Break-in – non-invasive flowmeters in hygienic applications
High Intensity LED Module for Photochemical Flow Applications
Borealis™ from Uniqsis isanewhigh intensity LEDlamp unit, available inarange of fixed wavelengths (370, 410, 440, 460and520nm), that converts their Cold Coil™ standalone reactormoduleintoaflowreactor for pho- tochemical applications. Both the Borealis™ LEDlamp andthe Cold Coil™ reactor modules require liquid cool- ing from eitherapiped water supply oraclosed loop re- circulator. Fitted withasafety interlock, to prevent accidental ex-
posure to high intensity light, the LED lamps are powered byaprogramable power supply that automatically de- tects the wavelength of the Borealis™ LEDmoduleand adjusts the output characteristics
accordingly.Atem- perature sensorandsafety cut-out are fitted to protect the LEDs from overheating.AnInert gas purge input is provided for low temperature use.

Katronic clamp-on, non-invasive ultrasonic flowmeters have been supplied to a major biomedical product manufacturer. Removing the need to compromise the cleanliness of the process by breaking into pipes to fit the meter has helped site engineers to significantly reduce project lead time and costs. There are many processes where
clean operation is imperative, for example foods, fine chemicals and biosciences. Clean-downs and changeovers can take a long time, and so can the paperwork and permissions process that allows new equipment to be installed. Katronic channel partner and instrumentation specialists WE Instrumentation found that one of their key customers had a real issue gaining permission to instal new flow measurement, with typically six months of investigation and effort before permission would be granted to break into site pipework to install new instruments. The costs of the equipment itself was dwarfed by the costs of the decision-making process and installation, making it very difficult for site engineering staff to propose and implement process improvements in a timely way. WE Instrumentation’s Martin Adams introduced Katronic clamp-on flowmeters to the site engineers. Katronic’s Matt Bird visited site and demonstrated the equipment by quickly achieving a good flow measurement using a hand-held KATflow 200 portable flowmeter. A key advantage of Katronic equipment is that the ultrasonic core of every meter in the range is the same, so a measurement made with a portable meter absolutely mimics the performance of a fixed flowmeter. Installation is straightforward with Katronic’s unique Audible Positioning Assistant that guarantees accurate sensor positioning. Following the successful demo, an initial order of Katronic fixed systems was purchased, followed with further orders after the first batch had proved to be as successful as the demonstration.

COMPACT AND VERSATILE: PS216-Q200/-Q210 PULL-WIRE SWITCH
New components for automation technology
The Schmersal Group launches a new pull-wire switch that can be used as a signal generator to start machines, open electrically operated guard doors and gates and as a light switch in lift shafts. Key benefits of the new PS216 switch are its compact dimensions and extreme versatility, enabled thanks to high degrees of protection under EN 60529 and suitable for use in a wide range of temperatures.
Thanks to IP66 degree of protection, the PS216 pull-wire switch is protected against dust and strong water jets and thanks to IP67 degree of protection, is also protected against temporary submersion in water. The switch can be used in ambient temperatures ranging from -30°C to +80°C.
Another practical benefit is that the PS216 operates according to
the ‘start/stop principle’ in that it remains switched on after initial actuation and subsequent release. Only when the switch is actuated and released a second time is the latch released and the switch switched off.
The PS216 pull-wire switch comes in two versions – the Q200 has a
holding force of 45 N and is suitable for wire lengths of up to 50 m, while the Q210 has a holding force of 70 N and can be used with wires stretching up to 100m. Pulling on the pull wire actuates the switch function in the pull-wire switch.
Other distinctive features of the PS216 include cable entry via M20 or M12 connector and six different NC/NO contact variants.
