Description of the principle of displacement sensor

First, what is the spool displacement sensor
The position of the spool of the hydraulic control system can be fed back by the displacement sensor. The typical sensor is the LVDT spool displacement sensor. The measurement principle of differential pressure transformation has the characteristics of high precision, good linearity and fast response speed. The unique sealing method and isolated electromagnetic induction technology make the LVDT spool displacement sensor can withstand up to 35Mpa. Widely used in hydraulic control fields, such as servo valves, reversing valves, proportional valves, and macro servo cylinders.
Second, the characteristics of Soway spool displacement sensor
1, withstand high pressure, can withstand 35MPa
2, output switch or 2 line 4-20mA or 3 line voltage signal
3, 4-wire switch signal, 6-wire AC
4, working voltage 9 - 28V DC, power consumption <2W
5, wide measuring range (2.5 - 35mm)
6, highly integrated small size
