Mainly responsible for measuring and controlling material levels.The application of ash hopper level gauge is very wide, which can measure position parameters such as liquids and solids. It measures the position quantities that are difficult to directly measure in storage equipment through various engineering principles, and can output electrical signals, making it easy to achieve automatic control. Simply put, a level gauge is an instrument that measures the position of an object! The ash hopper of a dust collector is a crucial component in dust collection equipment. It collects the waste dust during the dust removal process. In the case of widely used bag type dust collectors, when the smoke containing a large amount of dust at the inlet collides with the bag that blocks the dust under strong negative pressure, the larger part of the mass directly falls into the ash hopper, while the smaller part of the mass dust adheres to the surface of the bag and mechanically shakes under the external force of the anti blowing or pulse jet valve airflow to achieve the dust cleaning process. All the cleaned dust falls into the ash hopper. Dust collectors that are in working condition for a long time generally work continuously, cleaning the dust in online compartments. At this time, a large amount of cleaned dust * falls into the ash hopper, but the volume of the ash hopper is... Limited, so there must be a feedback signal to the PLC before the dust hopper is filled with dust The system is designed to schedule time to clean the dust in the ash hopper in order to continue working. At this time, a controllable ash discharge valve is usually installed in the ash hopper to facilitate the transfer of dust. The feedback signal in the above process relies on the level gauge, which is an instrument installed in the ash hopper to detect the position of dust in the hopper. With it, it can know how much ash is in the hopper, so as to organize work. Level gauges can be divided into RF admittance level controllers, heavy hammer level gauges, resistive level gauges, resistive rotary level gauges, and tuning fork level switches.
