Abstract
PURPOSE: To obtain an output corresponding to only the blocking of a filter all the time by actuating a display etc., by the difference in outputs of pressure and wind between upper stream and lower stream of the filter of a dust collector, an air cleaner, etc.
CONSTITUTION: As the blocking of the filter 2 increases, the diffrence between the pressure P1 in the upper stream 6 of the filter and the pressure P2 in the lower stream 7 of the filter becomes greater and thereby the output 9 of the pressure difference detector 8 is increased. Since the output 12 of the wind amount detector 11 is small when the amount of wind is small, the output of the differential type amplifier 13 goes great and the display 14 deflects in a wider range. When the amount of wind is great, where there is a difference in pressure between upper and lower stram of the filter, the output of the differential type amplifier is small even the ouput of the pressure difference detector 8, and thus the deflection of the display 14 is small. When the diffeence in pressur between upper and lower stream of the filter is increased due to the blocking of the filter 2, the output of the pressure difference detector 8 and the differential type implifier 13 become great and therefore the display 14 deflects largely.
