The new 4080B/BT piezoresistive sensors from Kistler feature advanced electronics and fully media-separated measuring elements

Designed for high-precision pressure and temperature monitoring in harsh motorsport environments, the new Type 4080B and 4080BT piezoresistive sensors are exceptionally rugged. According to Kistler, they offer constantly reliable operation in addition to maximum measurement accuracy and signal quality.

The new sensors feature integrated high-precision signal conditioning and a very wide, fully compensated temperature range, from 25 to 150°C (77 to 302°F). An entirely media-separated measuring element ensures reliable operation with maximum measurement accuracy and signal quality. Enhanced electromagnetic compatibility also guarantees operation and measurement accuracy in environments exposed to electrical or electromagnetic effects.

Their compact dimensions mean that the new sensors can be used for all standard onboard applications in motorsport. The most compact model – Type 4080BT – is ideal for demanding applications in the most confined spaces, and is available in pressure ranges of 5, 10 and 20 bar. As well as the media-separated measuring element, this sensor features an integrated PT1000 temperature probe, making it ideal for measurements in fuel systems, cooling water circuits or transmission applications. Based on integrated signal conditioning, the measuring element supplies voltage output signals for the pressure module and temperature probe. These advantages make the Type 4080BT suitable for universal use. The sensor also offers maximum flexibility for connection to a data acquisition system.

With pressure ranges of 5, 10, 20, 130 and 250 bar, Type 4080B offers a wider pressure range than Type 4080BT. Optional plug-and-play LEMO connectors save time and effort when connecting either sensor to the test bench.
