Winterthur, April 2022 – Kistler's new 4017A piezoresistive absolute pressure sensor combines excellent measuring features with universal applicability. Thanks to its compactness, innovative design and outstanding media compatibility it is optimal for use in engine development as well as hydraulic and pneumatic applications, in both hot and cold environments.
Piezoresistive (PR) pressure sensors consist of a silicon-based Wheatstone bridge which changes its electric resistance when exposed to pressure. This PR effect means that the sensing element is free of drift to a great extent – and is ideal for capturing static pressures. The PR pressure sensors can also be used for dynamic pressure measurements due to their ability to capture rapidly changing pressures even in low-pressure ranges. That is why such sensors became a standard choice in automotive applications, where precise measurements in the engine air and fuel path are required – but also for subsystem development such as brakes and cooling applications, that require high precision sensing.
