Wideband frequency response piezoresistive pressure transducers target small vehicle research

August 06, 2012 //By Julien Happich
Meggitt Sensing Systems has launched rugged, miniature, high-sensitivity Endevco piezoresistive pressure transducers to support the rigorous demands of small vehicle research and development.

The piezoresistive pressure transducers can be used for high-reliability fuel consumption analysis (air-to-fuel ratio), airbag inflation and safety testing, vehicle transmission testing, anti-lock brake systems (ABS) testing, hydraulic systems monitoring, and high-speed train external pressure variations. The Endevco piezoresistive pressure transducer models feature a four-arm strain gage bridge, ion implanted into a silicon diaphragm, for a wideband frequency response.

This unique sculptured diaphragm design produces twice the sensitivity of traditional flat diaphragms, resulting in improved resolution. Integral hybrid temperature compensation of these transducers further provides stable performance over a temperature range of -18°C to +93°C, with custom ranges upon request. Units offer lightweight, rugged construction and small diameters, for installation within space constrained environments. They are offered in multiple ranges with up to 300 mV FSO (depending upon model) and excellent non-linearity of <1% to three times over-range with up to 10X minimum burst pressure, up to 20,000 g shock resistance and high stability in temperature transients.
