Its a very mature non-contact absolute position detection data communication sensor technology. It consists of four parts: Grey Busbar, Antenna Boxes, Address Code Generator and Address Decoder. Grey Busbar likes a ruler with scale, Antenna Boxes similar to pointer, pointer location is the current position. No need to set original reference point. It has a five millimeter location accuracy, able to do make-and-break or continuous detection, especially for uneven rail or circular motion location detection. Generally, Grey Busbar is installed beside the rail, Antenna Boxes fixed on crane. Position value can be received on ground or crane. Address information can be transferred via own sensor, data radio or signal cable. One Grey Busbar can used on multiple movable machines and the length can be designed by project requirement. Several pieces of Grey Busbar can be connected together. With the performances of water-proof, grease-proof, dust-proof and anti-erode, it has no theoretical life cycle, widely used for severe environments like metallurgy, hydraulic engineering, open-pit mi
