  • Repeater of tandem sensor system
    Patent number: 6452162
    Abstract: A relay device for a concatenated sensor system includes first and second relay units (14, 16) and a relay cable (28) connecting the two relay units. When the first relay unit is located in intimate contact with one side of a sensor unit (8) that is situated at one end of a sensor unit group (4) or with one side of a master unit (2), a linking connector of the relay unit is connected to an input-output connector provided on one side of the master unit or on one side of the sensor unit. When the second relay unit is located in intimate contact with the other side of a sensor unit that is situated at the other end of a sensor unit group (4 or 6), a linking connector of the relay unit is connected to an input-output connector provided on the other side of the sensor unit. Thus, electrical connection between the master unit and the sensor unit group and between the sensor unit groups of the concatenated sensor system can be established with reliability.
