A device for measuring a gap between two objects located remotely from a user includes a base, a slider and a wedge. The slider is slidably received in the base and the wedge is attached to the slider and also slidably received in the base. A push-pull cable has a proximal end connected to the slider. The wedge is inclined at a predetermined angle and slides along an angled surface of the base such that a force applied to a distal end of the cable causes an upper surface of the wedge to move vertically forcing the wedge and the base into respective contact with the two objects forming the gap. By measuring the distance that the push-pull cable slides, the vertical distance traveled by the wedge and thus a measurement of the gap may be determined.
A device for measuring a distance between two objects, comprising:
The device of claim 10, wherein the distal portion of the flexible actuator comprises a sliding indicator arranged to slide along a measuring scale such that movement of the inner cable relative to the outer casing can be determined. 13, The device of claim 12, wherein the flexible actuator has a threaded connection with the base.
A method of measuring a gap between a rotor and a stator in a turbine with a gap measuring device, the gap measuring device comprising a base including an upper surface and a lower surface such that the upper surface is disposed at an incline to the lower surface, a wedge having a top surface and a bottom surface such that the bottom surface is arranged to slidably engage the upper surface of the base wherein the bottom surface is disposed at an incline that matches the incline of the upper surface such that the top surface of the wedge and the lower surface of the base are disposed parallelly to one another, and a flexible actuator having a first end coupled to the wedge such that a force applied to a second end of the flexible actuator causes the bottom surface of the wedge to slide relative to the upper surface of the base thereby causing a distance change between the parallelly disposed top surface of the wedge and lower surface of the base, the method comprising:
