Abstract (en)
[origin: EP0473295A2] A molten metal detection sensor provided with hermetically sealing means for sealing an internal space of the sensor. The molten metal detection sensor includes a hollow holder (3) assembled in a metal mold, an electrode rod (1) extending through the holder (3) and an insulator (2) interposed between the electrode rod (1) and the holder (3) at one end portion of the holder (3) confronting a molten metal path. A rear open end of the holder (3) is attached with a lid member (15) for hermetically confining an internal space of the holder (3), and a filling material is filled in the internal space. One end portion of a lead wire (9) is connected to the electrode rod (1) for transmitting a molten metal detection signal to an external device. The lead wire extends through a wall of the holder (3) at a penetrating portion (14) where a tubular member (17a) is provided to surround the lead wire (9). The tubular member (17a) is engageable with the wall of the holder (3), and a top end of the tubular member is sealed by a sealing means (18). <IMAGE>
