PURPOSE:To obtain a sturdy and highly practical detector against turbulence such as acoustic noise and vibration, by providing a reinforced layer formed from a polyurethane-oriented foaming agent having a through hole at the center within a capsule. CONSTITUTION:A reinforced layer 12 formed from a polyurethane-oriented foaming agent is provided at the center in a capsule 9 and has a through hole 13 arranged along the length thereof. A first signal cable 3 and a first power source cable 8 electrically connected to a sensor body 1 and a power amplifier 4 are put through the through hole 13. With a damping action of an external force by the reinforced layer 12, it is possible to reduce the application of turbulence such as acoustic noise and vibration to the cable 3 significantly thereby realizing a sturdy and highly practical magnetic detector. |
