The mesoscopic particle monitor is widely used in the fields of environmental protection and production process control, such as emission monitoring and maintenance of dust collectors, measurement of pneumatic conveying flow of solid particles, and various output interfaces make it flexible to use in different occasions. The unique digital signal filter design can effectively remove all kinds of electromagnetic interference and keep the instrument stable under severe working conditions. High precision and large range cover the measurement range of particle two-phase flow from dust emission to pneumatic transportation; Its continuous automatic zero baseline tracking and deviation elimination function enables the circuit to achieve zero deviation and zero drift without manual zero inspection on a regular basis; It has the functions of automatic continuous probe pollution, fault detection and range span detection.
