Abstract: A device for sensing the displacement of working members in industrial equipment is disclosed. The above sensing device includes cheap analog inductive sensors capable of maintaining the sensing characteristics irrespective of moisture and leaking water, thereby precisely sensing the displacements of the working members. The sensor housing of the device easily fixes the analog inductive sensor by simply fitting the sensor into a mount hole formed in the housing, thereby easily changing the troubled sensor with a new one and easily focusing the sensor when initially mounting the sensor to the housing. As a pair of analog inductive sensors are mounted to both side surfaces of the working member, the sensing device of this invention also prevents the operational errors to the sensors caused by the operational vibrations of the working members while sensing the displacements of the working members.
