PIEZORESONANCE ANALYZER OF VAPORS AND GASES Russian patent published in 2000 - IPC

Abstract RU 2145707 C1

FIELD: monitoring of atmospheric pollutants. SUBSTANCE: piezoresonance analyzer of vapors and gases incorporates gas line made of absorbing filter with sorbent, chamber with piezo-resonance sensor and flow agitator, measurement device composed of measurement generator, unit measuring changes o frequency. It also has second flow agitator connected to inlet of absorbing filter. Controlling input of second flow agitator is linked to proper output of control unit. It is preferable to install agitators of fan type in proposed analyzer with fan blades made of inert materials. EFFECT: increased measurement precision, prolonged service life of such analyzers used for analysis of corrosive media. 1 cl, 1 dwg, 3 tbl
