| 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 7S / 9S can be installed into a housing using an O-ring seal, or it can be welded. Welding should only be made to the flange at the rear of the transducer. Performance specifications will remain unaffected by the installation or welding process. The O-ring seal may be fitted directly below the flange, or as a peripheral seal at the front face of the transducer. The rear flange can be modified or machined off completely where space is important. The thin flange and outer capsule wall ensure that mechanical mounting stresses are not transmitted into the measuring cell. The structure also has good thermal conductance and the sensor closely tracks the process media temperature. The transducer is constructed from 316L stainless steel, using a high temperature hydrogen brazing technique, the brazed 316L diaphragms are highly resistant to corrosion. 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. Every pressure transducer is subjected to comprehensive tests for pressure and temperature characteristics, and is delivered with an individual calibration certificate (except for version 7SE / 9SE). Special testing is available on request from the customer. 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. |
