The optical air contamination monitor which has the solid-state forma anemometer, and this anemometer

摘要

(57) Abstract Objective Being accurate, power consumption is little, the wa is in the operation range the tsuThe te in the temperature which changes soritsudosute which substantially is unrelatedHaving anemometer, and solid-state forma anemometer of to formaIs the optical air contamination monitor is offered. Constitution The flow of the atmosphere in flexible pipe 12 is led to the fumes detectorProviding in the shielded tube 13 which for the sake of is interposed in the wall of flexible pipe 12And others the re it is being the anemometer, being enclosed into glass, flow of the atmosphereThe Zener diode which is bleached in the re (the component for the sample) 10With, to be deeply protected inside tube 13, in ambient temperature the position?The re it is the Zener diode (the standard component) to have 11, daioAs for join wire of do 10 inside tube 13 printed circuit board of fixingTo be adhered by 14 mechanically and electrically, bias resistance and the latter partThe electronic circuit is left from tube 13 far. Wind velocity of this configurationThe meter being accurate, is actual in the temperature which changes low in the power consumption and operation rangeBecause qualitatively it is unrelated, it applies to the optical air contamination monitorIt can do ru thing.
