Trend monitor with 4-20mA output

S304 Emission monitor that can be calibrated to give mg/m3 output

Based on Sintrol’s proven Inductive Electrification Technology, the S300 series has a detection limit of 0,01 mg/m3, while maintaining its globally recognized reliability and robustness. Available features allow the S300 series to be used for a wide
variety of applications such as stack-, process- and filter house monitoring. It can be installed into process applications like baghouse, cyclone, dryer or other dust collection systems to monitor particulate emissions as well as filter performance.

The S300 series is also often used for process control in applications where the dust levels need to follow designated limits. The onboard relays of the S300 series can be used as a dust level ALERT / ALARM signal. The mA output and the RS485 interface makes the instrument ideal for trend monitoring applications. Very short response time is a typical characteristic of Sintrol’s dust monitors, enabling early detection of malfunctions in the dust removal process and prevention of expensive product loss to the environment.
