Piezoresistive pressure sensor Series 7 S / 9 S / 9 FL

for the aerospace industry

The Series 7S / 9S is the latest development in media isolated piezoresistive silicon chip pressure transducers. The new low mass one-piece housing is smaller with a brazed stainless steel diaphragm for lower production cost, giving excellent long-term stability combined with easy installation. The Series 7 S / 9 S transducers are constructed from 316L stainless steel, using a high temperature hydrogen brazing technique; the brazed 316L diaphragms are highly resistant to corrosion. The diaphragm of the Series 9 FL is laser welded with the housing. Electrical connection is made via a five pin header. Leadout wires, or a PCB, can be soldered directly to the header pins. Series 7SE / 9SE versions are supplied with PCB fitted. Typical applications are, heating pumps, autoclaves and dialysers. Other applications include measurement of altitude, avionics, meteorology, servo controls, robotics, hydraulics, hygienic and pharmaceutical engineering, drift mining, injectors, and many more.
