DUST MONITOR


DUST MONITOR

For Detection of leakage of dust collector and bag filter breakage
Concentration 0mg/㎥~1000mg/㎥
measurement
range
Gas flow rate 4.0 m/s or greater
Output signal 4 to 20 mADC (500Ω)
Contact output
: 2 NONC contact for upper limit alarm,
: 1 NONC contact for fault alarm

Dust Monitor continuously measures for 24 h the dust in exhaust gas at the secondary side of a dust collector or the like and outputs the alarm signal at the abnormal condition and monitors the relative variation of dust amount with an analog signal. It detects the triboelectric charge of dust hitting the sensor probe and make outputs relative to the dust amount. Dust Monitor can be easily mounted on the existing facility to facilitate environmental management.

INTRINSIC SAFETY DUST MONITOR

For Detection of leakage of dust collector
and bag filter breakage
Enclosure Ex ib ⅡB T4 (Intrinsic safety)
Concentration 0mg/㎥~1000mg/㎥
measurement
range
Gas flow rate 4.0 m/s or greater
Output signal 4 to 20 mADC (500Ω)
Contact output
: 2 NONC contact for upper limit alarm,
: 1 NONC contact for fault alarm

Dust Monitor continuously measures for 24 h the dust in exhaust gas at the secondary side of a dust collector or the like and outputs the alarm contact at the abnormal condition and monitors the relative variation of dust amount with an analog signal.
The intrinsic safety enclosure enables it to be used in the hazardous area: Zone 1 & 2.

DUST SWITCH

For detection of broken bag of compact dust collector
Particle size 0.3 micrometer of higher
Velocity 4.0 m/s or higher
Output signal open collector output (NPN)

DUST SWITCH continuously monitors for 24 hours the filter condition of the general-use compact dust collector. It can quickly detect a very small amount of dust at the abnormality and make the dust leakage known. As well as DUST MONITOR, it detects the triboelectric charge of dust hitting the detection probe. DUST SWITCH is working environment protection sensor and can be easily installed on the existing facility.
