At this point, the signal from an identical oil leak sense wire 45 is inputted in oil leak sense wire 45, by making partial pressure electricity
Hinder R1, the position of the corresponding piping of the resistance value of R2, R3 ... and it is different, can be obtained by the position of the transistor Tr of corresponding oil leak position
Output.For example, making the 47 (component of detecting part of the resistance value of divider resistance R1 with the oil leak sense wire 45 of the position with piping
48) resistance variations are consistent, if thus there is the sensing of the output 1 from transistor Tr1 to export, it is known that right for from being piped
The oil leak for the position answered.
By being configured to as it appears from the above, the happening part of oil leak can be determined easily, and buried tank 1 can be carried out easily
Study for a second time courses one has flunked.
