Abstract

PURPOSE:To make the detector durable and increase the detecting precision thereof by transducing differential pressure into an amount of mechanical displacement and by detecting this amount of mechanical displacement consecutively. CONSTITUTION:At the time of stoppage of driving of a closed hydraulic circuit system with pressure chambers A and B of the differential detector built in the circuit, a through bolt 8 does not move and a magnetic resistance element 19 detects a point 0. When the pressure in the pressure chamber A rises, diaphragms 6 and 7 are bent to displace the through bolt 8. At the same time, the number of magnetic lines of force which a magnet 15 moving to the right integrally with the through bolt 8 delivers to the magnetic resistance element 19 is changed and thereby a resistance value is changed. Thus, the amount of displacement of the through bolt 8, i.e. the volume of load is transduced into an electric signal and this is delivered through the intermediary of a lead wire.
