50 Maintenance-Free pH Sensor for Harsh Environments
The Yokogawa FU24 is a new 'four in one' pH sensor designed to offer virtually maintenance-free operation and long sensor lifetime – especially in harsh applications involving severe temperature and pressure fluctuations. The new sensor incorporates a patented Yokogawa-designed bellows system, which automatically compensates for the effect of pressure fluctuations.
Such pressure variations can be highly detrimental to sensor operation, as they can initiate a pumping effect resulting from the expansion and shrinkage of the gel or liquid inside the sensor. The outcome is that the process liquid will start to ingress into the sensor and the reference voltage - and hence the pH measurement - will start to drift.
In the FU24 sensor, pressure fluctuations are automatically compensated by the built-in bellows up to 10 bar, making the sensor virtually insensitive to pressure variations. A positive overpressure maintained by the tension in the bellows generates a steady flow out of the sensor.

Online Library of Technical Filtration Information
Porvair Filtration Group has announced the publication of two new technical brochures adding to its comprehensive online library of product and applications information. The new 4-page technical documents provide an informative introduction to Porvair's popular Microfil and Polyfil filter product ranges. Each document includes a descriptive introduction, target applications use, key features and benefits, construction data, technical specifications, chemical compatibility and quality assurance information.
Microfil is a range of absolute rated, pleated glass fibre filter cartridges that can be used as both a prefilter and a final filter. Microfil filters have been designed to safeguard products by employing a high efficiency melt blown polypropylene layer downstream of the glass fibre media, whilst still offering the benefits of glass fiber media. Microfil cartridges are available as single or multiple module units of 5, 10, 20, 30 and 40 inches, in a range of three particle retention ratings: 0.5, 0.8 and 1.0 microns absolute - Beta 5000 (99.98% efficiency).

Polyfil cartridges are the filter of choice for organisations seeking absolute removal of unwanted particulates and for prefiltration to membrane filters. The unique high surface area pleated polypropylene design of Polyfil cartridges helps to achieve lower running costs and a smaller process footprint. Polyfil cartridges are also highly resistant to integrity failure caused by steam sterilisation and have excellent chemical compatibility characteristics.

With the ability to be controlled automatically or man ually, this easy-to-use system can be supplied with glass vessels ranging from 100ml to 3 litres, which can be changed in less than one minute. Designed for applications where elevated pressures are required, the Potassium Pressure System is ideal for protocols requiring hydrogenation, carbonylation.
Offering powerful overhead stirring and a temperature range of -80 to +200°C, the basic system provides automatic temperature and stirrer control, as well as pressure sensing.
In addition, PED/ASME compliance, a burst disc and pressure relief valve makes the system extremely safe.
Modes of operation include: manual pressure control, automatic pressure maintenance, pressure control with mass flow monitoring, mass flow control and off gas monitoring.
Control via the Atlas base can be manual or automated, enabling the simple logging of all data to a .csv file, which is easily downloadable to a USB stick.
In addition, optional PC control offers advanced functionality, including the complete automation of all parameters, alarms and real- time graphs.
