DUST MONITOR
Dust Monitor

Detection of caused by dust level
dust collector bag breakage or leak

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.

Concentration measurement range

0mg/㎥~1000mg/㎥

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 SWITCH
DUST SWITCH

For detection of broken bag of compact dust collector

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.

MICROWAVE FLOW SWITCH
Microwave Flow Switch

Non-Contact Movement Detection Sensor

Microwave Flow Switch, applying the principle of Doppler Effect, is a flow detection sensor for bulk solid/powder applicable to various application like flow monitoring of pneumatic feeding line, plugged chute detecton, etc... High performance in flow and plugged detection for dry powder. Hardly influenced by adhesion or dust because of high permeability microwave system. Self-diagnosis function automatically detecting decrease of sensitivity. Digital circuit system preventing set value from drifting. Withstanding pressure ability up to ±980kPa internal- pressure in pipe.

Setting range

Max. 1.5m

Frequency

24GHz band

Allowable pressure approx. ±980kPa(9kgf/cm2)or below

MICROWAVE FLOW MONITOR
Microwave Flow Monitor

Monitoring the relative flow rate balance of multi-branched piping system

The Microwave Flow Monitor is a solid flow sensor with the microwave technology. It can monitor the relative balance of flow rates in multiple branch pipes divided from a main pipe and since the total flow rate of branch pipes and the one of a main pipe are monitored, it is possible to check the balance of flow rate and control the flow rate. Also it can be applied to various solids and since there is no protrusion inside pipe, no clogging will occur. Further it can be used for the various applications such as a combustion boiler, a blending bin and a distribution system.

POWDER FLOW METER(SolidFlow / DensFlow)
SolidFlow

Continuous inline monitoring of powder flow rate

The SolidFlow is a measuring system specifically developed to measure the flow rate of powder and bulk solids through piping. The latest microwave technology is applied to enable continuous and highly accurate measurement of powder and bulk solids. The SolidFlow is particularly effective for measurement of low concentration flows and the DensFlow for high concentration flows.
