The various functions available mean that the ZiDM series can be used for a wide variety of applications: 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 ZiDM series is often used for process control in applications where dust levels must not exceed defined limits. The integrated relays of the ZiDM series can be used as alarm signals for dust levels.
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 feature of the Fuji Electric dustanalyser . It enables simple, intuitive setup. During the Auto Setup procedure, performed under normal process conditions, theanalyser automatically adapts to process conditions and sets the measurement range and alarms according to these conditions. Under normal conditions, the instrument displays a green LED and the mA output is set to 5% of scale.
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 analysers ZiDM-4 EMIDUST and ZiDM-3 MONIDUST are equipped with a local user interface for configuration and adjustment.
The operator can view measurement values in real time on the 4-digit display, in mA, % or mg/m³.
The 4-button interface allows the operator to navigate through the menus and modify the most important parameters.
An additional button to start the automatic configuration procedure is located next to the display.
Since 1993, our dust measurement technology has been recognized worldwide, with over 17,000 installations in more than 50 countries.
The measurement principle has become a proven standard for the accurate detection and quantification of dust levels.
Numerous laboratory test campaigns have also demonstrated excellent linearity on different types of dust.
The graph below illustrates the mA output in the ISO 12103 standard test (Arizona Road Dust Test).
Temperature tests showed close to no impact over the whole temperature range.
The ZiDM series is available with a wide range of probes and process connections.
The new mechanical solutions reflect our field of experience over the last twenty years.
The ZiDM series has been designed and developed to adapt to industrial processes and customer requirements.
The ZiDM series is supplied with a 500 mm probe made of 316L stainless steel and Ryton insulation. This probe withstands temperatures up to 300°C and pressure up to 600 kPa. The quick-release clamp enables the instrument to be removed quickly and easily. This is particularly useful in harsh process conditions, where probes need 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 analysers ZiDM series can be networked using a Fuji Electric 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 analysers ZiDM series can be managed and parameterized with DustTool software. This provides a convenient platform for viewing measurement results, initiating auto-tuning and adjustinganalyser parameters.
Plug a USB cable directly into the USB connector, or use a generic USB-RS485 converter, then simply connect to the unit's RS485 bus.
DustTool will automatically detect the interface being used and connect to the device.
