1. Introduction
1.1 Safety
ProSens sensor is powered from the transmitter.
DIN Rail Transmitter requires 24 ±10 % V DC power.
Caution:
The duct has to be exposed to a clean atmosphere during installation.
As such, the following should be considered:
• The gas flows or dust can be hazardous.
• Those flow can be inflammable, explosive, etc.
• The gases can be hot or under pressure.
1.2 Product Overview
The ProSens dust measurement systems are microprocessor-based and are pre-adjusted instruments for
measuring dust burdens in an airstream. ProSens is designed to monitor the clean air section behind filter
components and for measuring dust concentration in exhaust air ducts.
It is a compact unit consisting of a sensor and transmitter, enclosed in an IP 66 enclosure, which has been
specifically designed for easy installation and operation.
The standard transmitter is enclosed in the IP 65 housing and incorporates a touchscreen.
A DIN Rail Transmitter is also available, which is configured using the PC software.
The PME provides USB and RS 485 interfaces for PC configuration, the DIN Rail version can communicate
via RS 232 or RS 485 interfaces.
The PC software allows for configuration and calibration, which included the setting of internal parameters
like filter time, alarm hold time, etc.
With the software it is possible to monitor signal trends and to log protocol files.
ProSens is designed process pressures up to 2 bars and process temperature up to 250 °C.
An optional version is to be used in EX-zones category 1/2 gas & dust.
The sensor is connected to the transmitter using a 4 wire cable.
1.3 Mode of Operation
ProSens utilises tribo-electric technology whereby the interaction of dust particles with the sensor rod causes
a small electric charge, when the particles pass or hit by the sensor rod.
This small electric charge generates a signal proportional to the dust level even with an accumulation
of particles on the sensor rod. Experience has shown that this method of sensing dust level in gases offers
accurate results with a minimum of maintenance.
With power applied the unit is ready-to operate using factory setting and can be configured and calibrated
using the PME or PC software. For DIN Rail versions a PC is required for commissioning. Programmable
maximum & minimum alarm outputs are available. If the relay is used as “normally closed” (NC), the sensor is
also monitored for power failures. Also any other failure will be activated.

The transmitter has a 4 ... 20 mA output proportional to the trend of the dust burden.
If there is an error found by internal system checks the output is set to 2 mA.

ProSens-BA-EN-2015-01-29.indd 4 30.01.15 12:31
The best location for installation of the ProSens is in a duct section where there is even laminar flow
distribution.
The optimal position would be in a horizontal or vertical section of the duct. There should not be bends,
valves, dampers or other obstructions, either upstream or downstream, for a distance of at least 5 times the
pipe/duct parameters. (See figure 2)

Operating Instructions

In some applications a compromise has to be made and the sensor will have to be fitted in a position that
satisfies the majority of above requirements.
The sensor has to be attached to metal ductwork so that it will be electrically shielded from interference and
be provided with good grounding. For non-metal ducts, a section of the duct, a minimum of 5 x diameters in
length, should be covered with a metallic foil or fine-mesh on the periphery of the duct.
Caution, ensure good grounding practice are adhered to.
1. The unit should be installed in a position, where the gas flow passes the sensor rod at an angle of 90°.
2. In round cross-section ducts the unit can be installed in any position above the horizontal axis
(between 9 and 3 o’clock). (See figure 2a)
3. For square cross-section ducts, the unit must be positioned in the middle of the top or in the middle of
one of the sides. (See figure 2b)
4. Although the sensor is not affected by vibration, very high vibration levels should be avoided.
5. The units should not be installed in direct sunlight or in areas where the ambient temperature is above
60 °C.
6. The sensor rod must not contact the opposite duct wall or any other obstacle inside the duct!
The sensor can be shortened to a minimum length of 70 mm. Be careful not to damage the plastic cap
when doing this.
• The recommended length of the antenna is the pipe diameter minus 10 mm, ensuring there is no
contact with the opposite wall.
• The minimum length of the antenna is 1/3 of the pipe diameter, the smaller the dust burden, the
longer the antenna should be.
7. When monitoring an electrical filter system, the minimum distance from the filter is 20 m.
Although vibration does affect the measurement, the sensor should not be subjected to excessive
vibration for long periods of time.

2.2 Sensor Installation
Once the location of the sensor has been selected, the R 1” female thread is welded on the duct wall.
Then the G 1” male thread, of the sensor is screwed in until the connection is tight. Sealing has to be
checked.
Caution:
•Use a correct installation tool (wrench opening = S36) and turn at the G 1“ location. Do not screw in the
sensor manually by turning at the housing. This may lead to a faulty installation and cause damage to the
sensor.
• Warranty will be void if improperly installed.

Fig. 11: Dimensions of DIN Rail Transmitter
6. Operation
As the dust travels in the duct, it has kinetic energy. When the dust strikes the sensor rod, this energy
transform to static energy. A resultant coulomb charge builds up. This charge is processed to give a dust
burden reading.
After power up the ProSens starts measuring using factory setting.
The commissioning with PME can be done optionally with the touchscreen or with the configuration-
software. For the DIN Rail Transmitter, only PC configuration is possible.
The menu structure and numbering is identically for the touchscreen as well for the PC software. Therefore
the detailed description is valid for both versions. Variations from this will be explained separately.
6.1 Basic Operation of the PME-Touchscreen
To enter the configuration menu press the touchscreen in the upper, right section for a few seconds.
The main menu will appear displaying the firmware version and as well four operating buttons on the right
side of the screen.
- upwards button
- downwards button
- C button (in some parts of the menu named E button)
- enter button
To navigate through the menu use Up- or Down-button, to enter another level press Enter button. To leave
one level or to finally leave the configuration menu press C button (cancel), as well for leaving a particular
selection. In some menus this may be named E button (escape).

Operating Instructions
14
If a numerical value is required to be entered, a numerical keyboard will appear on the screen, for
alphabetical inputs, left and right arrows select the position, the up and down arrows scroll through the
selected letters.
Principally all inputs have to be confirmed by pressing the Enter button or have to be cancelled by pressing
the C button (E button).
After leaving the configuration menu, prompts will appear, Save Changes, Yes or No.
At this point all changes are stored or cancelled. This section of the menu will only appear if changes have
been made, if not the display will read the measured value.
6.2 Basics for PC Configuration
The DIN Rail version communicates via RS 485 or RS 232 interface, the PME version via RS 485 or USB
interface. The advantage of communicating via RS 485 interface is the possibility transmitting over longer
distances (>100 m), the transmission distance of USB and RS 232 are only possible over short distances
(< 5 m). Another advantage for RS 485 communication is the possibility to connect a many devices to one
ModBus line. If there is no RS 485 interface available it is possible to order from SWR engineering.
On the PME the RS 485 cables are connected to terminals ModBus A(+) and ModBus B(-), for the DIN
Rail version they are terminal numbers 12 and 11. The factory setting of the COM parameters is a Baud rate
of 9600 and ModBus-address #1. The complying COM port depends to the PC configuration and will be
displayed in the PC´s device manager. This is valid for all three communication versions.
The termination of the RS 485 interface is by a two wire connection. The RS 232 connection to the DIN Rail
Transmitter is via a specially supplied cable. For USB connection to the PME, it is suggested a standard, over
the trade counter, USB cable be purchased. For first up operation, drivers for the USB to serial port have to
be installed from the software CD.
On start-up of the configuration software, for first up operation, the communication parameters have to be
set on the upper Left Hand Side of the software window.
If the software has been started, in the German language, right click the “Sprache: Deutsch”, in the status
bar, and switch to the English version.

To enable communication, click the “Read device” button. If the communication has been established
successfully, you will see a message “MDS-Control configuration loaded”, otherwise an error message will
be displayed. If this is case, cabling and parameter setting have to be checked, and the software has to be
restarted.
To save any changes in the configuration, the “Device program” button on the Left Hand Side of the window
has to be clicked to send the new parameters to the transmitter.

6.3 Configuration
The configuration consists of four sub menus:
1. Measuring Range
2. Calibration
3. Outputs
4. Alarm
The four menu points:
The numbering of 6.3 adheres to the PME menu configuration and the same as to the PC software, not to the
numbering in this manual.

1.4 Filter time Input 0 – 99.9 s, smoothing of the measuring value by a floating average.
2. Calibration (Please note, numbering of PME and PC software is different)
The principle of calibration is to give dust load values to a corresponding raw value. The raw value is a
dimensionless number coming from the sensor, a low value for zero conditions (mostly from noise) and a
higher level with the complying dust concentration. The higher the dust concentration, the higher the raw
value.
2.1 Calibration factor Input 0.01 to 99.99, adjustment of the measured value, multiplies the

2.2 Zero calibration Zero calibration (the first calibration point), acquiring of an arbitrary amount
of samples. These will be incremented until triggering “Enter” or “C (cancel)”
button. Preferably this will be performed in Stop condition of the airflow
system.
2.3 Zero point If there was no zero condition during calibration the reference value for this
condition has to be set here.
2.4 Interpolation Calibration point, this requires a certain number of samples. These will be
point calibration incremented by triggering “Enter” or “C (cancel)” button. The unit will collect
raw values and will finally calculate the average of the samples. Then a
reference value has to be taken and compared to the calculated average

2.2 Zero point Zero calibration (1st calibration point), this requires a certain number of
samples. To start, click Enter button, beside the raw value cell. These will be
incremented by triggering “Save” or “Abort” button. Zero calibration should
be performed without any flow.
2.3 Interpolation point Interpolation point calibration, this requires a certain number of samples.
Click the Enter button, beside the raw value cell. These will be incremented
by triggering “Save” or “Abort” button. Pressing the “Save” button will open
an Input window for the reference value. This can be edited at a later stage.
Calibration point and raw values can be edited at any stage.
PC configuration To save this calibration values it is necessary to activate the check box
“Overwrite Calibration” on the left side of the window and also click the
“Device program” button. This must be done in order to save the results.

7. Maintenance
Maintenance is limited to cleaning the sensor as a routine maintenance task. The sensor must be thoroughly
cleaned ensuring that no particles have adhered to the rod as this could create a conductive path to ground.
There is no maintenance required for the transmitter.
8. Warranty
Warranty is for one (1) year. It starts from the delivery date. The warranty is valid as long as the system has
been installed and commissioned according to the Operating Instructions and there is no sign of any wear
or mechanical damage.
In the case of defects during the warranty period, all defective components will be repaired / replaced.
The parts that are replacing the defective parts, remain the property of SWR. If the costumer requires the
warranty work to be executed at their premises, then the costumer will pay for costs of the SWR engineer to
be on their site.
SWR is not responsible for any damage to the customer’s process and is not responsible
for any loss of profit due to that damage.
9. Troubleshooting
9.1 Alarm relay does not work
1. Check power supply and terminal connections.
2. Check parameter for alarm setting, are all time settings correct?
9.2 No measured value, even so after calibration
1. Check whether the process is running in a normal condition and whether there was normal conditions
during calibrating. Check if there was a real zero condition during zero calibration and that there was a
normal dust load during the interpolation point calibration.
2. If using the software: Has there been raw values displayed during the calibration procedure?
3. Check power supply and cabling.
4. Check for conductive and/or a short-circuit conditions between the sensor rod and the duct wall.
Also check for any particles sticking to the sensor rod or any condensation surrounding the sensor rod.
If the unit still fails the before mentioned checks, please your local distributor or contact
SWR engineering Messtechnik GmbH directly.
