Abstract:
1. A cylinder stroke system with a laser proximity detector, the system comprising: a. a pressure containing tube comprising a first tube end and a second tube end; b. a cylinder rod movably disposed within the pressure containing tube, wherein the cylinder rod comprises a cylinder rod first end and a cylinder rod second end; c. a piston disposed on the cylinder rod first end; d. a first fluid port formed in the pressure containing tube, wherein the first fluid port is in fluid communication with a first fluid source, and wherein the first fluid port provides a first fluid to the pressure containing tube adjacent the cylinder rod; e. a second fluid disposed within the pressure containing tube, wherein the second fluid is isolated from the first fluid by the piston; f. a blind end cap and mount having a cap portion connected to the first tube end and a mount portion connected to the cap portion; g. a laser secured to the pressure containing tube in communication with a laser controller, wherein the laser generates a beam, and wherein the beam causes a reflection from the piston; h. at least one optic guide disposed through the first tube end for directing the beam from the laser and through the second fluid to contact the piston; i. a lens separating the at least one optic guide from the second fluid; and j. a camera in communication with a main controller, wherein the camera receives the reflection from the piston and converts the reflection into a reflection signal, and wherein the camera transmits the reflection signal to the main controller to determine a position of the cylinder rod in the pressure containing tube.
