Patent ID: 8291769

Claim:
Multipurpose transducer (MPT) for an appliance using water, the multipurpose transducer (MPT) being provided with a temperature transducer (TT) and a turbidity transducer (TurbT), which are fixed on a first side of an electrically insulating mounting support (MS), on whose first part of said first side a transparent housing (TH) is fixed in a watertight manner, and with a pressure transducer (PT) fixed on said first side of the electrically insulating mounting support (MS), said transparent housing (TH) covering the temperature transducer (TT) and the turbidity transducer (TurbT) and a wiring (W) to them made on the mounting support (MS), and on one of its other sides of which a first transmission-line coupler (TLC 1 ) is fixed, whereto the wining (W) is conducted, characterized in that the pressure transducer (PT) is an uncompensated strain gauge, that the pressure transducer (PT) is fixed on a second part of said first side of the mounting support (MS) and that the wirring (W) connects the pressure transducer (PT) to the first transmission-line coupler (TLC 1 ).
