Length and angle sensor unit

Detecting angle and length

Lwg consists of a shell, a coil spring and a spring chamber, a length measuring cable and related installation accessories. A length sensor, an angle sensor, an electronic slip ring mechanism and a pcb circuit board are arranged inside the shell.  The lwg is installed on the side of the telescopic arm. One end of the length measuring cable is fixed on the lwg and the other end is fixed on the head of the telescopic arm after passing through the reel.  The reel rotates synchronously while the boom expands and contracts. According to the number of turns and the radius of the reel, the length of cable pulled out can be measured to obtain the telescopic length of the boom.  A pendulum angle sensor with damping can measure the angle between the arm support and the horizontal line.   Lwg208 has a length measuring range of 0 ~ 33 meters and lwg322 has a length measuring range of 0 ~ 56 meters, and a larger measuring range can be customized according to the requirements of customers.
