Description
The piezoresistive pressure sensor Type 4005B…is a small, rugged general purpose sensor available in absolute pressure ranges up to 250 bar. Operating in difficult test applications over a
temperature range of –40 ... 125 °C the Type 4005B... utilizes a
fully active four arm Wheatstone bridge to generate an electrical signal which is proportional to the applied input pressure.
The Wheatstone bridge is implanted into a silicon measuring
element, a proven technology which provides significant advantages but in particular reduces hysteresis and repeatability errors. The sensing element is packaged within a M5x0,5
housing using Kistler’s DCE (Direct Chip Exposure) method of
construction. This technique has many benefits allowing Kistler
to provide accurate miniature sensors with a high natural frequency, reduced thermal error, low acceleration sensitivity and
an excellent non-linearity specification.

The sensor Type 4005B… is available in a number of variations
including those that are suitable for use with Kistler amplifiers
Type 4665 and 4618A... . Equipped with PiezoSmart®, an active sensor identification system, it is possible to reduce set-up
time and improve overall installation consistency when used in
conjunction with the amplifier Type 4665. When calibrated with
a Type 4618A2 it is possible to monitor both the pressure signal
and the sensor temperature via scaled electrical signals.
Application
The small size and excellent dynamic response of the Type
4005B… allows for high quality pressure measurements to be
made in locations where other sensors may not fit. The sensor
is well suited for the measurement of gas pressure close to the
intake valve. The sensor can be used for a variety of measuring
tasks especially of gaseous (non conductive) media.
