Measuring device e.g. pressure sensor, for measuring operating parameter in water guiding parts of e.g. washing machine, has screen arranged in and/or at housing such that magnetic cooperation of sensor and transmitter is uninfluenced

摘要

The device (1) has a housing (3), and a membrane (4) arranged at the housing, and a signal transmitter (5) staying in effective connection with the membrane. A signal sensor (6) magnetically cooperates with the signal transmitter. A screen (7) for an external magnetic field is arranged in and/or at the housing in such a manner that the magnetic cooperation of the signal sensor and the signal transmitter is uninfluenced by external magnetic fields. The signal transmitter consists of a permanent magnet that is attached to a magnet adapter (8). The screen is made of magnetically soft metal. The housing consists of ferrosilicon, carbonyl iron and ferrite.
