‘Diaphragms’

An Engineeringtalk guide

Start with the news release PH30F diaphragm pumps transfer viscous fluids from Ingersoll-Rand European Sales, which we summarised at the time by saying "Ingersoll Rand is to expand its ARO EXP Series portfolio of diaphragm pumps with a 3in ported 2:1 High Pressure pump. ". Several months prior to that, we featured the news release Simrit introduces CO2-reducing sealing concept from Freudenberg Simrit LP: "Simrit is offering seals and elastomer compounds designed to suit components used in the the agrigultural and construction plant industries that contribute to reducing CO2 emissions. ".

In August 2009, we covered the news from Impress Sensors and Systems - take a look at LVDT transducers offer reliability and long life which says: "Sam Drury, sales and marketing director at Impress Sensors and Systems, considers the advantages of using LVDT technology for pressure sensors in harsh environments, including the nuclear industry. ".

Take a look also at the news release from American Sensor Technologies, AST catalogue showcases 20 pressure sensors, as well as Impress Sensors to distribute Ashdown products from Impress Sensors and Systems, and PCB offers Series 113B and 102B pressure sensors from PCB Piezotronics.
