Four gas detector Product Overview Series vibrating rod level switch for alarm or control various silos fixed material level and the level of the various containers can detect liquid precipitates! Meter has no moving parts, and with corrosion, high sensitivity and convenient installation. Carbon monoxide gas detector solid materials: rice, milk powder, sugar, salt, washing powder, cement, stone, can liquid medium gas gas detector plastic particles: water, mud, pulp, dyes, oils, milk, wine, beverages and other works series vibrating rod level switch using a tuning fork "resonance" principle, the vibrating tube and built-in vibrator constitute 280Hz vibration frequency "tuning fork" resonance probe vibration in the drive piezoelectric element. When the probe touches the measuring object, the vibration amplitude polar distance is reduced, which was converted to an electrical signal, the relay switches to support dynamic operation ambient temperature vessel operating temperature (the order should indicate the operating temperature) vibrating rod Material: aluminum or stainless steel ( Users can customize the vibrating rod oscillation frequency: about supply voltage delay rate of vibration damping vibration rod rods media freedom delayed output signal s non-sticky material does not contain objects vibrating rod export line from corrosion around the explosion protection class contact capacity : Solid dust explosion (NA explosive places) material particles maximum dimensions liquid container order shall state the maximum pressure pressure) http://www.dingdinggroup.com/
