Stroke of the smart length-measuring hydraulic cylinder is detected through integrated displacement detection device. By identifying bar code covered on surface of the piston rod and optical detecting system installed on guide sleeve to get absolute location of the cylinder, movement of the main engine can be precisely controlled. The product applies to synchronous control, unmanned manipulation and malfunction diagnosis of engineering equipment.

Displacement measurement and identification technology with precision up to 0.1mm.

Reliable cycle index of length-measuring device≥500 thousand times.

Absolute optical location measurement without reference point of calibration.

Can completely replace traditional displacement sensor, and cost of the same measurement length is lower.

Unlimited stroke detection length, easy to maintain and not affected by external factors.
