| 摘要 |
<p>The invention relates to a position sensor (1) for oil-operated piston/cylinder units (30), being adapted for installation inside the cylinder and comprising a cursor (6) mounted for displacement inside a linear potentiometer (7) that is associated with one piston end to provide an indication of the piston travel. Advantageously, the potentiometer (7) and cursor (6) of the sensor (1) are housed within an armored case (3), and there is also provided a magnetic actuator (20) associated with the piston and slidable along the outer surface (4) of the rod in magnetic coupling relationship with said cursor (6). The steel structure of the case (3) is sealed to enable use of the sensor (1) under very high pressures. <IMAGE></p> |
