PURPOSE: A pressure-type water level detecting sensor is provided to fabricate the pressure-type water level detecting sensor at a low cost by simplifying a structure of the pressure-type water level detecting sensor. CONSTITUTION: A pressure-type water level detecting sensor includes a case(110), a pressure sensor(140), a circuit board(300), a supporter(120) and a tube(130). The pressure sensor(140) is installed at one side(111) of the case(110). A part of the pressure sensor(140) is exposed out of the case(110) in order to detect external pressure and the remaining part of the pressure sensor(140) is accommodated in the case(110). The circuit board(300) is installed in the case(110). The circuit board(300) includes a plurality of electric circuits for processing signals. A hole(112) is formed at the other side of the case(110). The pressure sensor(140) generates a voltage signal. The voltage signal applied to the circuit board(300) is outputted to an exterior through an output line(160). |
