<p>A sensor unit S for water heating systems, particularly for water boilers, is designed with a single housing H as a combined relative pressure and temperature sensor and has a ceramic support element C carrying an electronic circuit E including separate circuit zones E1, E2 for detecting the pressure and the temperature of the water, said support element including an active functional element M and being directly contacted by the water. The water contact area of said ceramic support element is separated from said electronic circuit E by a sealing 9 in said housing H. <IMAGE></p> |
