Sintrol S304: Continuous Particulate Matter Dust Monitor

Sintrol S304 is a continuous dust monitor that can be calibrated to mass concentration units (mg/m). For applications requiring absolute value measurements, it helps plant operators know the exact amount of dust passing through stacks or outlet ducts.

– Key Features: Equipped with a 4-20 mA output and two independent alarm relays to further optimize plant processes.

– Working Principle (Inductive Electrification): Utilizes advanced algorithms and signal filtration, combining DC and AC signals generated by particle contact and proximity to deliver highly accurate dust measurements.
