Modular absolute pressure sensor
09 January 2017
Designed to meet the demands of highly dynamic applications, the new absolute pressure sensors from Kistler Instruments cover pressure ranges from 0-5 bar to 0-500 bar.
The seven sensors all offer automatic sensor identification, wide dynamic range and digital temperature compensation. The modular design allows the sensor to be combined with a wide range of adapters to make the Type 4011A exceptionally suited to a wide variety of applications where highly dynamic events in challenging environments need to be monitored in real time with maximum precision and reliability.
The separation of the measuring element from the measured media by a welded stainless steel diaphragm ensures excellent media compatibility whilst digital temperature compensation minimises temperature induced zero point and sensitivity changes without impairing the signal bandwidth. Two temperature compensated ranges, -20 to 120°C and 15 to 180°C, allow a wide variety of applications and the temperature output allows the sensor element to be monitored to identify potentially damaging conditions before sensor malfunction is caused.
The Type 4011A can be used as a universal absolute pressure sensor to take measurements on exhaust systems with a cooling adapter but is equally suited to intake area or water pressure measurements. In addition, the new sensors open up new possibilities for exhaust gas back pressure measurements. Designed specifically for engines with an exhaust manifold integrated in the cylinder head, one version can be mounted directly or through the cooling jacket using a sleeve. The fully shielded cabling with kink protection together with the high-grade steel diaphragm ensures maximum lifetime, enhanced signal quality and increased functionality.
Although designed to meet the needs of automobile engine development and testing applications, the new pressure sensors are equally suitable for other dynamic, absolute pressure measurements in challenging applications where precision, integrated temperature compensation and long life are demanded.
