The rotary kiln large ring gear yaw measuring instrument is composed of a magnet, a proximity switch, a main machine, a converter, a rotating large ring gear, an electromagnetic probe and the like. At the time of operation, the inductive probe is mounted on the side of the large ring gear, and the magnet is attracted to the side of the large ring gear to be placed close to the switch and to enable it to generate a signal. Connect the switch and sensor to the main unit with a cable. The operating host can easily detect the radial yaw data of the large ring gear.
When using the measuring instrument, pay attention to the following points: 1. Since the range of the proximity switch is less than 20mm, pay attention to the radial displacement of the cylinder within 20mm when measuring; 2. Ensure the stability of the electromagnetic probe. In order to reduce the measurement error, in order to ensure that the probe does not touch the large ring gear, try to make the probe close to the large ring gear.
