NameElectrostatic dust concentration detector

Model: S303

summary:
Sintrol S303 dust concentration detector from Finland,It is an improvement based on the previous generation STD10 series. By adopting the principle of electrostatic induction and combining years of on-site experience, the accuracy, reliability, and ease of operation have been greatly improved. The calibration of the product is fully intelligent, representing the development direction of future electrostatic dust meters, with users all over the world.

Xinchuang S303 dust emission detectorIn addition to switch output, online continuous signals also have 4-20 mA analog signal output. Can be used to monitor changes in dust concentration trends. Usually installed downstream of filters, cyclones, or similar equipment to monitor solid particle concentration, prevent leaks, and provide early warning.

An insulated metal electrode is installed in the flue, using the principle of AC induction. The DC part of the signal is separated and stored, and only the AC part of the signal is used to calculate the dust content. When dust comes into contact with or passes near this insulated metal electrode, an electromotive force is induced inside the electrode. This electromotive force is directly proportional to the dust concentration. It is measured and amplified, and interference signals are filtered out through intelligent algorithm software before outputting a standard 4-20 mA signal. Measurement is not affected by adhesion on the probe.
