PURPOSE:To obtain a pair of function-type voltages throgh a signal detector, by distributing a pair of saturable coils close to each other in the right angle to each other. CONSTITUTION:A vertical sensor 10 which detects the vertical magnetic field and a horizontal sensor 11 which detects the horizontal magnetic field have a saturable core 5 and a winding 6 respectively. A core holder 12 is formed with the silicone resin or the like and into a body with a pair of saturable cores as if the core holder held these cores. The saturable coils of the sensors 10 and 11 are fixed onto the same shaft close to each other and vertically to each other. These two saturable coils are connected to the different wave detecting circuits via a cable respectively to form a detecting head. |
