Festo Canada has announced the MS series of pre-assembled filtration products designed to lower the risk of particle contamination when compressed air comes into direct contact with food or packaging in the food zone. The three different models in the series — MS4, MS6, and MS9 — conform to FDA and US Food M SSafety Modernization Act guidelines for clean air. The filtration systems fo aare rated for air flow ranging from the MS4 at 360 l/min to MS9 at 7,800 l/min. In addition to the three7 sstage filters, MS air preparation units ccome with a lockout/tagout feature. Red/green gauges indicate when filR ters require replacement.

T series EASMT/EASYMT PTFE bellows solenoid valve from The P Plast-O-Matic is designed for severe service applications with m most types of liquids. Units are suitable for pressure, drain or vvacuum service, and sizes range from 1/4 to 1 in. Valves are sspring return normally closed and direct-acting with a simp ple push-pull plunger design. There is no minimum pressure rrequired for operation. The PTFE bellows shaft seal is said to eeliminate the need for an elastomer seal which can weakeen as a result of chemical attack. The PTFE bellows assures ssmooth, non-sticking operation, the company says, and has a cycle life of over 2 million in laboratory conditions. The bello lows design also allows a stock valve to be used for vacuum o or pressure. The poppet seat ensures bubble-tight shutoff.

Brooks Instrument has made ISO/IEC 17025 certification available as an option on its SLA series Biotech mass flow controllers (MFC). Engineered specifically for the needs of the biotechnology market, the MFCs are used to precisely measure and control the delivery of process gases necessary for cellular metabolism in biotech applications, the company says. This certification, in addition to FDA/USP class VI/ADI-free elastomers and other certificates, satisfies even more regulatory compliance requirements for biopharmaceutical manufacturers that depend upon accurate flow control calibration for their applications. Highlights of the series also includes a broad range of analog and digital I/O options suitable for most biotech applications. An independent diagnostic/service port permits users to set alarms and diagnostics, tune, troubleshoot or change flow conditions without removing the mass flow controller from service. The series is said to provide a highly configurable platform based on a simple modular architecture. The feature set was carefully selected to enable dropin replacement and upgrade of many brands of mass flow controllers. Watch product video at www.cpec.news/hls.

The MIM electromagnetic flowmeter from Kobold Instruments measures and monitors small to medium sized flow of conductive liquids in pipes. According to Faraday’s Law of magnetic induction, a voltage is induced in a conductor moving through a magnetic field. The voltage induced in the measured media is proportional to the flow velocity and is therefore a value for the volumetric flow. The flow rate will be calculated based on the cross-sectional area of the pipe. The measurement does not depend on the process liquid and its properties such as density, viscosity and temperature. The two outputs can be independently sett to switch or provide an analog or frequency output. A batching function can also be selected. Watch demo at www.cpec.news/xke.
