Dust Concentration Meter "Dust Monitor" for Detecting Leaks and Tears in Bag Filters
PFM Series
Catch dust that cannot be visually confirmed! A dust concentration meter that ensures safety through continuous monitoring.
The dust monitor continuously measures the dust concentration in the exhaust gases on the secondary side of dust collectors and monitors changes in relative dust levels, outputting alarm contacts and analog signals in case of abnormalities. It detects the frictional static electricity of dust that comes into contact with or passes near the detection probe. It can be easily installed in existing setups and is useful for environmental measures. Additionally, it is equipped with a concentration correction function, allowing for output correction to the dust concentration obtained by JIS measurement methods by adding a correction factor to the detection signal. Changes in dust levels due to leaks or tears in bags can be monitored, and continuous concentration changes can be output at levels close to actual measurements, enabling trend management of dust collector performance to be monitored at values close to JIS measurement methods. Moreover, it has obtained domestic explosion-proof certification, making it usable in first and second category hazardous locations (zone 1.2). ● Domestic production ensures stable supply Maintenance only requires regular cleaning of the probe. ● Low cost with performance equivalent to optical methods Measurement range of 0 to 1000 mg/m³ with 9 range switches. Detectable particle size from 0.3 μm. ● No specialized knowledge required. Range setting and sensitivity adjustment can be easily made with a switch.
