Abstract
A torque sensor includes an adjustable platform vertically adjustable to place a sensing module near a rotating target to obtain measurements there from with a sensing element. The apparatus can be configured to include a bottom channel mounted to a base and a PCB tray mounted to a top channel, the PCB tray and top channel vertically adjustable from the base by a rotating shaft. The top and bottom channels are coupled to side bars and side channels in pairs movably connected by joint pins with a rotatable shaft movably connecting said joint pins. The sensing module is movable with respect to the base via rotation of said rotatable shaft causing movement of said pair of side bars and side channels, placing said sensing element nearest a target to obtain rotational movement data.
Claims20
A system, comprising:
- an adjustable platform including a base, a sensor carrier and a translatable component;
- and
- a torque sensor disposed on said sensor carrier and configured to receive a torque signal from circuitry disposed on a target shaft adjacent to said torque sensor;
- wherein said movable component comprises a top channel and a bottom channel mounted to said base, said top channel and said bottom channel coupled by a pair of side bars and side channels movably connected by joint pins and a rotatable shaft movably connecting said joint pins, said joint pins connecting said pair of side bars and side channels, wherein said torque sensor is movable with respect to the base via rotation of said rotatable shaft to cause movement of said pair of side bars and side channels, thereby positioning the torque sensor in greater or lesser proximity to said target.
A movement sensing system, comprising:
- a sensing module including a sensing element mounted in a PCB tray;
- an adjustable platform including said PCB tray mounted to a top channel and a bottom channel mounted to a base, said top channel and said bottom channel coupled by a pair of side bars and side channels movably connected by joint pins and a rotatable shaft movably connecting said joint pins, and said joint pins connecting said pair of side bars and side channels, wherein said PCB tray is movable with respect to the base via rotation of said rotatable shaft to cause movement of said pair of side bars and side channels, and wherein said sensing element is placed near a target after movement by said PCB tray to obtain torque data from said target;
- and
- at least one guide plates attached at a side of said at least one adjustable platform, wherein said top channel and said bottom channel in association with said pair of guide plates is evenly adjustable during movement of said rotatable shaft in order to permit said sensing element with said PCB tray to accurately engage a target, and wherein said sensing element detects and obtains torque data from said target.
A torque sensor, comprising:
- a pair of guide plates attached to sides of an adjustable mechanism and a metal screw, wherein said adjustable mechanism, in association with a pair of guide plates, is adjustable to permit a PCB tray including a torque sensing element to engage in vertical axis movement with a rotating shaft and thereby attain enhanced detection sensitivity and infinite resolution from said rotating shaft.
