In a previous Sensortech post entitled “Hydraulic Cylinder Position Feedback“, we discussed the basic concept of hydraulic cylinder position feedback. In case you might have missed that post, here it is for an encore appearance.
Magnetostrictive linear position transducers are commonly used in conjunction with hydraulic cylinders to provide continuous, absolute position feedback. Non-contact magnetostrictive technology assures dependable, trouble-free operation. The brief video below illustrates how magnetostrictive position sensors are used with hydraulic cylinders.
While we’re discussing hydraulic cylinder position measurement, here are a few more articles that are worth a second look:
