The existing linear sensor is usually one-sided coupling type, that is, the moving ruler is only installed on the side of the fixed ruler, so the measurement performance of the sensor can not avoid the influence of the gap change between the moving ruler and the fixed ruler, the difference of parallelism and other assembly problems. In order to achieve high measurement performance, the straightness of sensor installation and operation trajectory often needs to meet stringent requirements.
The reduction furnace is a traditional equipment for producing tungsten, molybdenum, chromium, nickel and other metal powders. The fifteen-tube furnace is one of the most commonly used multi-tube reduction furnaces. It is applied to the sensor part. The switch of the furnace door at the feeding end adopts mechanical structure. The whole pushing process is controlled by Mach proximity switch. The Mach proximity sensor obtains the position signal and the PLC controls the deceleration. Optional proximity sensor model specifications FBB-18D12P1-DS12, FAB-30D15N1-D3, FAB-30D25N1-D3, FAB-30D40N1-D3
By improving the structure and installation mode of the moving ruler and the installation mode of the fixed ruler, the sensor can effectively restrain the influence of the gap between the moving ruler and the fixed ruler, the parallelism difference and other assembly problems on the measurement performance, thus reducing the requirements for the straightness of the sensor installation and operation trajectory.
