Embodiment Construction

[0053] An inductive position sensor as shown in Figures 1 to 5 includes a read head 1, a modulation wheel 2, a drive circuit capable of outputting a drive signal, and a signal processing circuit, wherein the read head 1 includes a read head insulating ring 11 and a read head The soft board 12, the read head insulating ring 11 covers the inner and outer surfaces of the read head soft board 12, and the two form a whole, the read head soft board 12 includes a transmitter winding, a receiver winding and a cable 15 for signal transmission connection, The flexible board 12 of the read head is in the shape of an L-shaped square. The transmitter winding and the receiver winding are arranged in a thin layer area. The cable 15 is connected to the cable connector 16. The insulating ring 11 of the read head has a gap for connecting the read head. The corner of the connection between the soft board 12 and the cable 15, the joint of the read head soft board 12 and the read head insulating ri...

Abstract

The inductance transducer comprises the reading out head, modulating wheel, drive circuit and signal treatment circuit of the outcome drive signal, features in the insulation ring of the reading out head, reading out head soft plate, modulator and its insulation ring, with the synchronous wheels allocated on the coaxial shaft from the inside to the outside in ring distribution, with gaps between the reading out soft plate and the modulator, which comprises the modulating components and modulating soft plate, equal distance between the width between the modulating components and the adjacent two modulators, the corresponding circle center angle and component distance related circle center angle on the cross section of coal center equipped components of the arc for each modulating component are equal, and it is the same with the circle center angle of the negative ring unit and of the positive ring unit. It also opens an inductance transducer location sensor reel, with the said sensor installed inside the reel through the sensor shaft.

Description

technical field [0001] The invention relates to an inductive position sensor, and the invention also relates to a tape measure containing the inductive position sensor. Background technique [0002] The inductive position sensor is a tool commonly used by people to measure linear displacement. It has high precision, low power consumption and is easy to carry. However, the current inductive position sensors can only be used to measure linear displacement, and cannot be used for rotary or rolling measurement methods. Therefore, most of the current inductive position sensors are linear, while ring-shaped inductive position sensors have not yet appeared. A tape measure comprising a ring-shaped inductive position sensor has therefore also not been seen. At the same time, calipers are also commonly used measuring tools. At present, the commonly used calipers are electronic digital calipers, and there are three main types of common electronic digital calipers: capacitive position ...
