Pressure sensor: Compact design for harsh environments
No-diaphragm design fits in crowded, punishing applications.
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.

Annual Salary Survey
In a year when manufacturing continued to lead the economic rebound, it makes sense that plant manager bonuses rebounded. Plant Engineering’s annual Salary Survey shows both wages and bonuses rose in 2012 after a retreat the year before.
Average salary across all job titles for plant floor management rose 3.5% to $95,446, and bonus compensation jumped to $15,162, a 4.2% increase from the 2010 level and double the 2011 total, which showed a sharp drop in bonus.
