MULTIPURPOSE TRANSDUCER FOR AN APPLIANCE USING WATER
First Claim
1. 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, which transparent housing (TH) covers 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 (TLC1) is fixed, whereto the wining (W) is conducted, characterized in that it is provided with a pressure transducer (PT), that the pressure transducer (PT) is fixed on a second part of said first side of the mounting support (MS) and that the wining (W) connects the pressure transducer (PT) to the first transmission-line coupler (TLC1).

Abstract
A multipurpose transducer for an appliance using water, like a washing machine, a dishwasher or a hot-water tank converts physical parameters like water temperature, cleanness and pressure in said appliance into electric signals. It is provided with a temperature transducer (TT), a turbidity transducer (TurbT) and a pressure transducer (PT), all of them being fixed on an electrically insulating mounting support (MS). The pressure transducer (PT) is made as an uncompensated strain gauge in a thick film technology. The temperature transducer (TT) made as a termistor is also manufactured in the thick film technology. The multipurpose transducer (MPT) of the invention requires less work steps to be manufactured, mounted and connected in the appliance of said type than earlier transducers.
