Since Tangshan Steel Plant rolling mills, reducers and other equipment cannot be shut down for a long time for construction and wiring operations, a wireless vibration monitoring scheme is adopted to install wireless temperature and vibration integrated sensors on the sides, tops, and flanges on both sides of the upper cover of multiple reducers and rolling mills.
The length of the whole rolling steel is 90 meters, and the vibration detection frequency is at least 30 seconds / time, which puts forward higher requirements for battery power supply
In the working state of the sensor, there will be splashes of lubricating oil substances, and even the sensor may be wrapped, and the shell temperature will be above 50 °C when rolling steel, which has very high requirements for the protection level and temperature resistance of the sensor.
