Based on 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 make the instrument ideal for trend monitoring applications.
Very short response time is a typical characteristic of Fuji Electric dust monitors, enabling early detection of malfunctions in the dust removal process and prevention of expensive product loss to the environment.

The measurement is based on particles interacting with an isolated probe mounted into a duct or stack. When moving particles pass nearby or hit the probe, a signal is induced. This signal is then processed through a series of advanced algorithms to filter out the noise and provides the most accurate dust measurement.
Classic triboelectric technology is based on the DC signal, which is caused by particles making contact with the sensor to transfer charges.
Inductive Electrification Technology is based on the Triboelectric AC signal and it minimizes the influence of sensor contamination, temperature drift and velocity changes. By using Inductive Electrification Technology, it is possible to reach a detection limit as low as 0.01 mg/m³.
The Auto Setup function is a unique Fuji Electric Dust Monitor feature which allows for a simple, user friendly setup. During the Auto Setup procedure, which is done in normal process conditions, the dust monitor will automatically adapt to the process conditions and set the measuring range and alarms accordingly. At normal conditions the instrument will show green light and the mA output is set to 5% of range.
In case the measuring point is before the filtration system, the Auto Setup baseline could be several g/m³ and after the filtration system the Auto Setup baseline could be only a few mg/m³. In both cases, no manual range setup is required.
The S303 and S304 are equipped with a local user interface for setup and adjusting the instrument.
The operator can see the actual measurement values on the 4- digit 7 -segment display in mA, % or mg/m³.
With the 4-button interface the operator can navigate and change the most important operating parameters.
Next to the display, is a button to start the Auto Setup procedure.
Since 1993, our technology is globally recognized with over 20 000 installations in more than 50 countries.
The measuring principle has evolved into a proven standard for dust monitoring needs.
Extensive tests of S300 have been carried out in Finland and Germany. The results showed excellent linearity over various dust types.
The graph below illustrates the mA output on standard test dust ISO 12103 medium (Arizona Road Dust).
Temperature tests showed close to no impact over the whole temperature range.
The S300 series comes with a wide range of different probes and process connections.
The new mechanical solutions reflect our field of experience over the last twenty years.
The S300 series has been designed and developed to adapt to industrial processes and customer requirements.
The S300 series comes with a 500 mm long probe, made of 316L stainless steel with Ryton as an insulator material. This probe withstands temperatures up to 300 °C and up to 600 kPa pressure. The quick clamp enables fast and easy removal of the instrument. This is beneficial especially in difficult process conditions where the probe might have to be cleaned regularly.
Probe Lengths and Coatings (Optional):
A wide range of different probes are available as options to allow customized solutions. Adhesive and wet dusts may create a conductive dust build up on the probe which will negatively influence on the monitor’s accuracy and reliability.
As Inductive Electrification is based on the transfer of electrostatic load from the probe to the amplifier, conductive dust build up may lead to a bridging effect from the probe to the grounded ductwork.
To help avoid this bridging, Fuji Electric has developed a number of coatings for the different process conditions:
Used in process conditions with high probability of dust build up on the probe.
Air purge ensures that the base of the probe stays clean of dust build up.
The high-temperature probe can be used in process conditions up to 700°C.
The air purge option is not available for this sensor.
Flanges for process connection can be selected according to the customer's datasheet .
The S300 series is able to be networked using the RF platform.
This reduces cabling costs and eases installation with a fully integrated, easy to use RF connection.
Each monitor has a range of up to 1 km and can act as a repeater within the network. With directional antennas the range can be significantly extended.
Wireless network features :
The S300 series monitors can be managed and parameterized with the DustTool PC Software. This offers a convenient platform to view measurement results, to initiate the Auto Setup and adjust the parameters of the monitor.
Just connect a USB cable directly to a USB
connector or use a generic USB-to-RS485 converter and connect to the device’s RS485 bus.
DustTool will automatically detect the interface being used and connect to the device.
