Sensor device for measuring humidity, pressure and temperature in a hydrogen process gas stream in a Brennstoffzellenanordung, hydrogen fuel cell assembly and the use of the sensor device for measuring the pressure, the temperature and the relative humidity in a gas process flow for a drive unit

摘要

The device has a humidity sensor (80) placed close to a temperature sensor, and an electrical heat unit placed close to the sensor (80), where data output of the sensor stands in connection with a digital serial bus. The sensors and the unit are assembled together to form an integrated compact module. A main temperature sensor is placed adjacent to a module in gas process flow. A pressure sensor is situated close to the module.
