1. Introduction
1.1 Safety
The ProSens dust sensor requires a 24 ±10 % V DC supply. 24 ±10 % V DC is regarded as safe.
The DIN Rail converter requires a 24 ±10 % V DC supply. 24 ±10 % V DC is regarded as safe.
Precautionary measures:
The pipe must be opened for installation and maintenance.
The following risks must be borne in mind:
• Harmful escape by gas or dust.
• Escaping material may be inammable, explosive or toxic.
• Escaping material may be hot or pressurised.
1.2 Product overview
The ProSens dust sensor is a microprocessor-based, preset device for measuring dust concentrations
in a moving air stream. The ProSens serves for monitoring the pure side after lter elements and for
the quantitative measurement of dust concentrations in exhaust air ducts.
The ProSens is a compact device for simple installation and functioning. The sensor electronics are
accommodated in an IP 66 housing. The Evaluation unit is accommodated in a maintenance housing
with touchscreen as standard.
A DIN Rail converter is also available, which is congured via a PC. The PC conguration can be
carried out at the Field housing via USB or RS 485 interface.
USB or RS 485 communication is possible for the DIN Rail evaluation.
PC software, which can also be used to change internal parameters of the sensor (lter times, alarm
retention times etc.), is optionally available. This software also allows parameter les and log les
from the measuring value logging to be saved, with an additional option for trend visualisation.
The ProSens is designed for use in applications of up to 2 bar pressure and 500 °C.
The system can optionally be installed in explosive zones of category 1/2 gas + dust.
The sensor is connected to a 4-wire cable, via which the supply and digital communication is routed
to the Evaluation unit.
1.3 Reliability
For any additional information concerning product reliability, please contact ENVEA Process.
1.4 How the device works
The ProSens dust measuring instrument is based on the electrodynamic technology: Dust particles
streaming past or impinging on the probe exchange the smallest electrical charges with the probe.
These small electrical charges lead to a signal, which is proportional to the dust load in the air owing
past, even if particles accumulate on the probe.
A reliable measuring value can consequently be attained with this almost maintenance-free and non-
wearing measuring system.

4
The device is ready for operation immediately after switching on with default settings and is
congured and calibrated either with the Evaluation unit MSE 300 or with the conguration software.
The use of a PC is required for commissioning measuring units with DIN Rail evaluation. Freely
denable alarm thresholds for a minimum or maximum alarm are available within the measuring range.
If the relay contact “normally closed” (NC) is used, the sensor is automatically tested for power failure.
The internal error message from the sensor also signals any faults occurring via the relay.
The Evaluation unit provide a 4 ... 20 mA power output as a measuring value output or or as trend
display for the dust load.
If a fault is found during the internal function test, the power output is set to 2 mA.
2. Installation
2.1 Determining the installation site
The best installation position for the sensor in a duct or a pipe is located in an area, in which the
particles undergo a uniform distribution and ow past the sensor at a uniform velocity.
The installation site can be in a horizontal or vertical pipe.
In the best case, the duct or pipe continues upstream and downstream of the installation site
horizontally or vertically and ttings or manifolds, valves or slides have a minimum distance to the
sensor in both directions. (See Fig. 2)

Fig. 2: Recommended distances to valve, etc. (DN = nominal diameter)

The best possible installation location should be chosen in applications that cannot fully satisfy the
requirements for the installation location.
The dust sensor must be installed in a metallic duct in order to attain sufcient shielding against
electrical inuences.
In case of non-metallic lines, a metal casing, a metal foil or a ne-meshed metal net with a length of
approx. 5 times the pipe diameter must be provided upstream and downstream of the measuring point.
It must also be ensured that the duct and sensor are earthed properly.
1. The ProSens should be installed so that the dust impinges on the sensor rod at an angle of 90°.
2. In horizontal pipes with a round cross-section, the ProSens can be installed in any position above the
horizontal axis (between 9 and 3 o’clock). (See gure 3a)
3. In horizontal pipes with a square cross-section, the installation can be in the centre at the top or side.
(See gure 3b)
4. Even though the sensor function is not impaired by vibration, strong vibrations should be avoided, as
they can lead to destruction of the electronics.
5. The sensor should not be exposed to direct sunlight, or used in area with an ambient temperature of
more than 60 °C.
6. The sensor rod must not come into contact with the opposite pipe wall or any other device!
The electrodynamic signal would be short-circuited by this. The length of the sensor can be
shortened to a minimum length of 70 mm for this. The plastic sleeve must not on any account be
damaged here.
• The length of the sensor rod should be minimum 1/3 and maximum 2/3 of the duct diameter.
However, it must always be ensured that contact through bridge formation does not result,
even if deposits form on the inside wall of the pipe.
• A golden rule: the lower the dust concentration, the longer the rod length.
7. A position downstream of the blower is generally recommended as an installation position for
monitoring a lter system. If the sensor is used downstream of an electric lter, the distance to the
electric lter should be minimum 20 metres. Even though the sensor function is not impaired by
vibrations, very high vibrations over a longer time period should be avoided.

3. Safety
The sensor was designed, built and tested for safety and is shipped in this condition. Components within
the supplied system could be hazardous if not unpacked, installed, connected and commissioned by
authorised qualied persons. All operating instructions must be read, and understood, before handling the
system. Failure to do so will cause the warranty to be revoked.
3.1 Normal use
•The measuring system may only be installed for measuring the low ow rate in metallic pipes.
•Only original spare parts and accessories of ENVEA Process GmbH must be used.
3.2 Identicationofhazards
Possible hazards, when using the measuring system, are marked by the following symbols:
Warning!
•This symbolises a situation where personal safety is at risk if used in an improper manner.
Attention!
•This symbolises the possible damage to the system, if used in an improper manner.
3.3 Occupational and operational safety
•The measuring system must be installed by trained and authorised personnel only.
•Protective equipment must be worn to avoid injuries caused by possible sharp edges on the
measuring device.
•When using a cable with more than 4 cores, unused, open cores may cause sparking. Failure
to comply with the specied connection parameters of the cable will result in loss of intrinsic
safety. To prevent this, it is mandatory to use a 4-core shielded cable.
Always ensure that the connection parameters of the cable are within the specication (Li, Ci).
The shield of the cable must not be connected to the housing under any circumstances.
•When installed in an Ex zone, there is an increased risk of explosion, so it should always be
ensured that there is no Ex zone when carrying out installation work.
•Improper installation work leads to an increased risk of explosion. The device must always be
installed using the process-related seals and observing the torques. Mechanical stresses are to
be avoided, for example through supported installation.
•In case of improper assembly, there is an increased risk of explosion due to escaping dusts.
•Improper mechanical stress (e.g. torsion) can cause damage to the device. To avoid this, the
device should always be installed in accordance with all the instructions in the operating manual.
The measuring device should also not be exposed to any vibrations if possible.
•If the device is operated under high pressured conditions, there is a risk of explosion. When
cleaning or blowing out the pipe and when transporting material, always ensure that the
permissible pressure according to the DGRL is not exceeded.

9
•Due to the process, hot components on the device can cause burns. It is strongly recommended to
wear the appropriate protective equipment and to let the device cool down before working on it.
•Improper use of the device will result in a high risk to system safety, therefore the device must
only be used as specied in the associated documentation.
•Make sure that the system is in a depressurised state during all maintenance, cleaning and
inspection work on the pipelines or on the components of the device.
•In case of maintenance-work on the pipe or on components of the sensor, make sure that the
piping is in unpressurized condition.
•Switch off the power supply for all maintenance, cleaning or inspection works on the sensor or
on components. Follow the notes of the chapter maintenance.
•Caution, if welding is required on the pipe, remove sensor.
•The components and electrical connections must be checked for damages regularly. If a damage
is found, it is to be repaired before further operation of the instruments.
3.4 Maintenance
•For maintenance purposes, it is imperative that the device is de-energised and cooled down,
otherwise there is an increased risk of explosion.
•Before working on the device or its components, it is essential to ensure that they are de-
energised. Otherwise there is a risk of electric shock.
•The correct tool must be used to open the device, otherwise there is a risk of injury and
crushing.
•Before opening the device or its components, it is imperative to ensure that there is no EX zone.
•During cleaning work on the device or in the process, there is an increased risk of explosion due
to electrostatic discharges and excessive pressures.

6. Operation
The ProSens dust measuring instrument measures the dust content in a gas passing the sensor using
the electrodynamic principle by means of the exchange of charge carriers between the dust particles
and the sensor's probe.
After switching on, the ProSens already begins to measure with the default factory settings.
Commissioning can be carried out at the Evaluation unit MSE 300 optionally via the touchscreen or
with the conguration software. Only PC conguration is possible for the DIN Rail version. The menu
structureornumberingisidenticalfortouchscreenandPCconguration,whichmeansthedetailed
description for this applies to both versions in this operating manual. Any deviations from this will
be explained separately.
