Piezoresistive absolute pressure sensor employs direct chip exposure technology to provide superb linearity, minimal hysteresis and an extremely high natural frequency
The new miniature piezoresistive absolute pressure sensor, type 4005A, from Kistler uses new direct chip exposure (DCE) technology to provide superb linearity, minimal hysteresis and an extremely high natural frequency.
The M5 size sensor is ideal for measurements in intake ports, gas exchange investigations and many other static pressure measurements.
The DCE sensor design eliminates the need for an isolating steel diaphragm leaving the piezoresistive silicon element directly exposed to the gas.
A fine screen and protective coating minimise the risk of the element suffering physical damage.
This new design provides a high performance in a very small package, says Kistler.
