Summary
The dust warehouse environment, the material level measurement becomes a difficult problem; such as rotary paddle level switch, vibration rod type liquid level switch, capacitance level switch in general use for three months or so in a semi paralyzed state until the use to measure and control the measurement of ordinary. Summary of the reasons for the failure of the following: (1) the measurement of the material level is the use of the side of the installation, and the installation of the side of the meter depth of the instrument can not be more than one meter. Because the insertion depth of more than one meter will make the powder bin packing is inserted into the probe rod bending; (two) due to dust particles of dust are relatively small, the most easily formed positions within the internal hanging; (three) the production process caused by condensation, make bin powder hanging serious.
According to the analysis of the above reasons, in order to accurately measure the height of the material level of the dust removal chamber, the idea of measuring the probe can not be buried in the warehouse. Based on the comprehensive analysis of the domestic and foreign dust storage units of a variety of factors, according to the internal characteristics of the dust removal chamber, combined with the production of many years of experience in our plant, the invention of the dust chamber material level meter. It can fundamentally avoid back bin hanging submerged probe and can accurately measure the material level, and has anti friction anti solid impact corrosion resistance high temperature and other characteristics, so that long-term use and measurement in the dust bin completely.
Dust storage warehouse level instrument product features
1, strong adaptability: can be used in any dust collection, in high temperature, high pressure, strong corrosion, strong adhesion, strong dust free working environment.
2, no maintenance: because the sensor has the advantages of simple structure, no moving parts, all the operation without maintenance.
3, punctuation is simple: you can use any warehouse two points automatically complete punctuation.
4, the performance of a wide range: the ability to continuously measure or switch signals to show the location of the dust bin.
5, no temperature drift: not because of the temperature or density changes in the media drift
6, reliable life: unique technology to ensure the instrument life of up to 15 years

Installation of material level measuring instrument for dust collector
Internal structure of dust collecting bin:
In the design and production of dust storage chamber, in order to make the dust storage chamber is not deformed and screening large. Often in the warehouse or welding on the steel mesh. We want to make the transmission probe avoid hanging layer, in the transformation of old equipment is not changed under the condition of more must use steel or mesh layer in the bin.
Above we analyzed, we can adapt the dust removing bin transmission probe under the premise to precisely the warehouse material in the measurement, the key is to avoid hanging layer, which we use to dust bin channel or the screen. First we installed base probe required in the middle of the channel steel welding, the measuring probe from the installation base installed vertically, from the base to the signal along the channel leads to lower, so it can avoid hanging layer and can accurately and continuously put the dust silo level is measured.
