Abstract

In order to resolve the problem of hydraulic valve spool displacement detection

a structure of spool sensor based on Hall element is proposed.The overall structure and working principle of the withstanding voltage Hall displacement sensor is presented.The finite element model of the sensor is modeled.The relation between magnetic flux density and spool position is analyzed.A novel displacement sensor for spool is developed

and the experiment is investigated.The results show that the linearity of the sensor is 1 % in the range of 2 mm

the sensor can be used for the proportional valve spool displacement detection.
