Page 14: Principle Of Operation, Physical Effects, And Limitations
5 Principle of operation, physical effects, and limitations Sintrol dust monitors are based on a unique Inductive Electrification technology. The measurement is based on particles interacting with an isolated probe mounted into the duct or stack. When moving particles pass nearby or hit the probe a signal is induced.
Page 15: Particle Size
Particle size In terms of particle size, 425µm (40 mesh) is generally defined as the limiting size to classify a material as a “dust.” The minimum particle size which the Dumo is able to detect is 0.3 microns. The best working range of the Dumo is between 1 and 200 microns. Linearity, maximum concentrations, and calibration The measuring range and the behavior of the Dumo depends on many factors, such as the dust material (as explained in chapter 5.1 Influence of particle material), particle size, flow speed and installation location.
Page 16: Influence Of Flow Velocity At The Dumo
Figure 7: Effect of Ambient Temperature Influence of flow velocity at the Dumo Since the Dumo is equipped with an internal sampling fan which provides a constant flow speed. The fan is also monitored for changes in the performance to ensure a constant flow speed. In situations with high winds (>5m/s), the surrounding airflow may affect the internal flow speed of the Dumo and decrease the accuracy of the measurement.
Page 17: Mechanical Installation
6 Mechanical Installation Critical installations in health or explosion-prone areas, as well as use in all dust control  systems, need to be reviewed and approved by an expert consultant who is responsible for the integrity of the system design and compliance with locally accepted codes. Critical installations are considered to be such installations where a failure may directly or ...
Page 18: Distances And Grid Layout
Distances and grid layout  Dust always needs to move in form of airflows, winds, or clouds actively towards the Dumo.  Dumo’s fan accelerates the gas towards the probe only once it is very close to the duct inside the Dumo. The fan will NOT actively pull dust particles towards it. The pulling effect of the fan is already negligible at less than ½...
Page 19: Electrical Installation And Wiring
7 Electrical Installation and Wiring Pay attention when choosing the cable. It must meet and be installed according to all locally  applicable codes, and must be suitable for the environment it is going to be installed in.  Always use a shielded cable when possible. Make sure to connect the shield to a protective earth potential at a single location.
Page 20: Grounding And Usage Of Grounded Power Supply
Grounding and usage of grounded power supply Risk of injury! If the Dumo is not properly grounded, it may react to changes in the ground potential and show false results, resulting in severe health impacts to workers and/or a failure of the explosion prevention system. ...
Page 21: Connecting The Solid-State Relays (Ssr)
Connecting the solid-state relays (SSR) Alarm signals can be transferred as digital I/O signals using two dedicated wires. Signal levels conform to the power source voltage (V+ (1 and 2) and V- (C)). I/O signals are designed to be used as relatively short-range triggers for logic implementation or to drive external relays.
Page 22: Connecting The Ma-Output
Connecting the mA-output An active and isolated mA-output signal (mA+ and mA-) is used to transfer an analog 4-20 mA current signal that describes the measurement value. After the default auto-setup procedure, the normal signal level is set to be 5% of the scale (i.e. 4.8 mA). Thus, a max signal level of 20 mA indicates a 20-fold increase in dust levels since auto-setup.
Page 23: Connecting The Rs-485 Bus
Connecting the RS-485 bus TIA-485-A, also known as ANSI/TIA/EIA-485, TIA/EIA-485, EIA-485 or RS-485, is a standard defining the electrical characteristics of drivers and receivers for use in balanced digital multipoint systems. The standard is jointly published by the Telecommunications Industry Association and Electronic Industries Alliance (TIA/EIA). Digital communications networks implementing the EIA-485 standard can be used effectively over long distances and in electrically noisy environments.
Page 24: Connecting A Rs485 Network
Connecting a RS485 Network Multiple Dumo dust monitors can be connected into a single network. This ‘daisy chain’ connection allows for several devices to be communicated with using only minimal wiring. Both Modbus RTU and Sintrol Network protocols are supported. To use Modbus RTU protocol the RS485 bus needs to be connected to the CH-1 RS485 terminals according to the following schematics.
Page 25: Parametrization And Calibration
8 Parametrization and calibration Dumo requires minimal set-up time to get to regular operating conditions. For trend monitoring applications, it is enough to run the auto-setup procedure. During regular operation, the Dumo continuously measures dust concentrations and sets an alarm signal according to the concentration and pre-set alarm levels. The adjustment of the parameters can be done by using ...

Page 27: Auto Setup Description
Auto setup description The auto setup function is a unique Sintrol 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. The auto setup function analyzes the present measurement signal, determines the average value and establishes a normal operations baseline.
Page 28: General Usage Of The Display And 4-Key User Interface
General usage of the Display and 4-Key user interface The Dumo is equipped with a 4- Digit, 7- Segment display, 2 magnetic switched (option) and 6 key buttons. The optional magnetic switches are placed alongside the front-panel LED’s whereas the push buttons are inside the connection area below the circular threaded plug.

Page 35: Sintrol Dusttool Software
9 Sintrol DustTool Software Sintrol Dumo is equipped with USB and RS485 interfaces for connecting to DustTool. Both interfaces are preconfigured to use Sintrol Network protocol from firmware version 3.0.2 onwards. Connect a USB cable directly to a Windows PC or alternatively, use a generic USB-to-RS485 converter and connect to the device’s RS485 bus.
Page 36: Parameters Tab
PARAMETERS tab Figure 20: DustTool main window In the PARAMETERSS tab, you can modify the operating parameters of the connected dust meter. The basic operating principle to change parameters is as follows: 1. Change parameter to the desired value 2. Press the “Save” button to save the changes into the memory of the instrument. If the “Save” button is not pressed, the changes will not be sent to the device and the values will be lost at program shut down or when the instrument is detached.
Page 37: Wireless Connectivity Of Dumo
10 Wireless connectivity of DUMO The wireless connection operates on the proprietary Sintrol Network communication protocol. The protocol stack takes care of automatically forming the network and routing data within the network via the strongest available connection possible. It is recommended to name each Dumo in a wireless network before the installation. In this way, each device will be easily identified by the given name when the network is otherwise automatically created.
Page 38 Figure 21: Sintrol Network Example Wireless router (Optional): To use a wireless network, at least one additional unit is needed. This unit is used as the communication base station which converts physical signals into the radio network and back. The base station can also be connected to a PC via USB, where it is then possible to run Sintrol DustLog 8 data collection software to manage and operate the network online.
