Pressure sensor: Compact design for harsh environments

No-diaphragm design fits in crowded, punishing applications.

07/17/2008



The new 4007B pressure sensor from Kistler Instrument is designed for elevated temperature evaluations and R&D studies in harsh environments where space is a consideration.

Available in measuring ranges of 0 to 5 bar (0 to 72.5 psi) and 0 to 20 bar absolute from -40 to 200 °C, the sensor is 21 mm long and 6.2 mm in diameter with integral cable. The company says that using its direct chip exposure (DCE) design eliminates the need for a diaphragm. A piezoresistive measuring element measures static and dynamic events with excellent dynamic response. The sensing element relies on an implanted resistive bridge on micro-machined silicon which minimizes hysteresis and repeatability errors. Other performance enhancements include wide bandwidth improved by digital characterization techniques.

The series is available in a number of forms, including PiezoSmart compatible with IEEE1451.4 TEDS standard. When used with a Kistler 4665 series amplifier, 0 to 10 V or 4 to 20 mA outputs are available. mounting is required. The body is of 17-4 PH stainless steel with a M5X0.5 mount. The company says this design has been used successfully in punishing automotive intake/exhaust manifold pressure measurements, and engine oil/fuel pressure studies.
