Miniature pressure sensor uses new DCE technology

A miniature piezoresistive absolute pressure sensor, Type 4005A, from Kistler uses Direct Chip Exposure technology to give 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.

Established in Wintherthur (Switzerland) in 1957, Kistler is represented in over 50 countries and has subsidiaries in Germany, France, Italy, UK, Japan, USA, China, Korea and Singapore.

Heavy investment in research and development, 15% of staff worldwide are engaged in research and development, has generated a number of innovations using piezoelectric, piezoresistive and capacitive techniques to provide solutions to numerous force, pressure and acceleration measuring problems.

These innovations include the world's first commercial quartz sensor, two-wire constant current technology to integrate sensors with microelectronic circuitry, high-temperature pressure sensors for use up to 3500C and three-component force measuring sensors.
