Kistler has announced the latest addition to its 4080A range of piezoresistive absolute pressure sensors for motor racing applications: the Type 4080AT combined pressure and temperature sensor. The new M6 miniature sensor features a temperature probe and integrated signal conditioning, designed to cope with harsh ambient conditions and it can be installed directly in the vehicle or test bench.
The Type 4080AT supports reliable monitoring of pressure in hydraulic, cooling water or oil circuits, allowing for early detection of problems, optimization of system design and real-time monitoring of critical conditions for operation.
Thanks to a media separated measuring element, the sensor can operate reliably with maximum measuring accuracy and signal quality criteria that Kistler is crucial in motor racing applications. The additional integrated PT1000 probe allows dynamic temperature measurements in liquids at up to 200°C. The 4080AT features maximum flexibility for connection to a data acquisition system thanks to a unique concept that includes integrated signal conditioning and an analog voltage output from 0.2 to 4.4 VDC (pressure) and 0.5 to 4.5 VDC (temperature).
Optimized calculation algorithms also mean that the compensated temperature range is now increased to a maximum operating temperature of 150°C – so the sensor meets the demanding requirements for modern onboard sensor technology.
The Type 4080AT is FIA-homologated and can be supplied in variants with a LEMO plug connector or a flylead cable, and is available as from the end of 2015.
