0000000984 00000 n TE is one of the largest sensor companies in the world. A pressure sensor can also be designed to perform as a pressure switch, which generates a simple on/off signal that will change state when a preset threshold is reached. 0000069596 00000 n endstream endobj 22 0 obj <> endobj 23 0 obj <> endobj 24 0 obj <>/ColorSpace<>/Font<>/ProcSet[/PDF/Text/ImageC]/ExtGState<>>> endobj 25 0 obj <> endobj 26 0 obj <> endobj 27 0 obj <> endobj 28 0 obj [/ICCBased 43 0 R] endobj 29 0 obj <> endobj 30 0 obj <> endobj 31 0 obj <> endobj 32 0 obj <> endobj 33 0 obj <>stream ����c�I荁�NϹoֻ�?

There are several common terms associated with pressure measurement devices that are often used interchangeably. 0000000016 00000 n The devices are designed using ST’s VENSENS technology, allowing the fabrication of pressure sensor on a monolithic silicon chip, eliminating wafer-to-wafer bonding and maximizing reliability. This stress is usually pressure but can be twisting, bending, or vibrations. Follow us on Social. A sensor capable of compound pressure measurement is one that can measure both positive and negative (vacuum) pressures. 0000001900 00000 n 0000006229 00000 n case of the oil and gas industry, downhole pressure sensors require pressure ranges up to 35,000 psi at temperatures that can be as high as 200°C. 6 0 obj << /Linearized 1 /O 8 /H [ 1073 219 ] /L 116122 /E 114355 /N 1 /T 115885 >> endobj xref 6 32 0000000016 00000 n 0000001443 00000 n trailer << /Size 38 /Info 4 0 R /Root 7 0 R /Prev 115876 /ID[<558b3e780c6cd318fdbefc04267336e5><538f1101eeaa4b8a3693d67fb159dba9>] >> startxref 0 %%EOF 7 0 obj << /Type /Catalog /Pages 3 0 R /Metadata 5 0 R /PageLabels 2 0 R >> endobj 36 0 obj << /S 36 /L 117 /Filter /FlateDecode /Length 37 0 R >> stream �CM�R�#��. 0 A pressure sensor is a device for pressure measurement of gases or liquids.Pressure is an expression of the force required to stop a fluid from expanding, and is usually stated in terms of force per unit area. ...
