Claims (1)

[Scope of utility model registration request] A pair of sensors that can be installed at a distance from each other between two items that should face each other in a parallel state, a DC power supply connected to this sensor, and an indicator connected in the middle of this circuit to detect electrical changes in each sensor. The above-mentioned sensor has a strain-sensitive conductive element whose resistance value changes depending on the applied strain between a pair of electrodes, and the facing state between two articles at each sensor position can be electrically changed. A parallel state detection device that can be read.
