2.3 LOW PRESSURE SENSORS FOR ENGINE DEVELOPMENT
LP22DA
TIEZ1821A.01
The M8 water-cooled low-pressure indicating sensor LP22DA
measures the absolute pressure in the exhaust system of
combustion engines. The sensor is available with the pressure
range of 10 bar. This piezoresistive sensor is used for precise
measurement of static and dynamic pressure variations. Typical
applications are gas-exchange analysis, precise friction analysis
or turbo charger development. The integrated water-cooling
allows mounting the sensor into very narrow spaces of the
exhaust manifold. The sensor is equipped with an integrated
amplifier featuring digital thermal compensation.
