The sensing elements utilized in ShrewdShoe have been designed in an innovative way, they are based on a barometric pressure sensor covered with a silicon coating. The presented sensing element has great linearity up to 300...

in this study, a cylindrical bolling probe was developed and evaluated for measuring stress in soil under tire traffic. the probe consists of a silicon rubber head for sensing the soil stress, a pvc tube for transferring the liquid pressure, a digital pressure sensor and a syringe for filling the probe with water and adjusting the initial inclusion pressure. a tank with pressurized air was used...

The small silicon chip of Schottky diode (0.8 × 0.8 0.4 mm3) with planar arrangement electrodes (chip PSD) as temperature sensor, which functions under the operating conditions pressure was developed. forward current-voltage I–V characteristic PSD is determined by potential barrier between Mo and n-Si (ND = 3 1015 cm?3). Forward voltage UF 208 ± 6 mV coefficient TC -1.635 0.015 mV/°C (with line...

Pressure control valve (PCV) is implemented in internal combustion engine to regulate crankcase pressure. In this study, the performance of a diaphragm PCV valve is investigated numerically and experimentally. Firstly, numerical simulation is carried out using commercial code to predict the flow and pressure distribution inside the valve. Furthermore, downstream and upstream pressure of the val...
