MODEL100 output 4-20mA bag dust collector leak detector

Description :

　　1MODEL100Overview of bag dust collector leak detector:

　　The MODEL100 bag filter leak detector measures the electrostatic induction of dust particles passing through a fixed probe. Dust particles and probes induce static charges, which are amplified by the probe and transmitted to the monitoring and control system. The size of static charge is proportional to the flow rate of dust particles. The high-tech electronic circuit of the MODEL100 bag dust collector leak detector converts this part of the charge into a control signal output, triggering the alarm for excessive dust emissions, and continuously recording the total amount or concentration of dust particles. This device provides the latest communication coupling technology in the world. This is a modern, accurate, and stable monitoring technology, particularly suitable for continuous emission recording and data accumulation. The working principle of this monitoring system is to use the charge induction generated by the flow of dust particles around the probe to confirm the online emission amount (mg/sec) or emission concentration (mg/m3) of dust particles. In the case of relatively stable combustion conditions (i.e., at the same emission point, there is no significant change in flow rate, temperature, pressure, humidity, and smoke particle properties, with a variation of less than ± 90%), the MODEL100 bag filter leak detector can also be used for online monitoring of emission concentration (unit=mg/M3) after direct calibration.
