WGS-B type open space dust online monitor

■ General

WGS-B is a special detector for the concentration of total suspended particles. Based on the electrostatic principle, when charged dust passes or collides with the sensor in the measurement channel, it generates an electromotive force on the sensor (proportional to the dust concentration). WGS-_ B The DC part of the electromotive force is filtered out as a reference through the intelligent algorithm program, and the AC part is used for dust concentration calculation.

The laboratory and field practice has proved that WGS-B can measure the environmental dust with the concentration lower than lmg/m, and can detect 0.3 μ M diameter dust particles.

WGS-B is equipped with two alarm signal outputs: early warning and alarm, and three color indicator light: green (normal); Yellow (early warning); Red (alarm). During the use, the site workers can be informed of the change of the ambient dust concentration at that time, so that measures can be taken as soon as possible to avoid equipment damage and personal harm.

WGS-B also has continuous 4-20mA current output and RS485 communication interface, which can be conveniently connected to the system.
