Electro-inductive dust monitor - ZiDM-3 MONIDUST

Specifications

Based on proven inductive electrification technology, the S300 series has a detection limit of 0.01 mg/m³ and retains its world-renowned reliability and robustness. The various functionalities available mean that the S300 series can be used for a wide variety of applications: in emission measurement, industrial process control or filtration system 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 often used for process control in applications where dust levels must not exceed defined limits.

The built-in relays of the S300 series can be used as dust level alarms. The mA output and RS485 interface make this instrument ideal for trend monitoring applications. The very short response time is a typical feature of Fuji Electric's analysers dust monitors. It enables early detection of malfunctions in the dust abatement process and prevents costly product loss.
