The miniature pressure transducer M5 takes its name from the fine M5 thread at the sensor head that makes it possible to take measurements in places which are difficult to access and in narrow pipelines. Together with its ability to measure media at temperatures of up to 180 °C in a dynamic range from 0 to 50 kHz, this makes it ideally suited to measurements on engine test benches.
