1.1 Purpose of this Manual
This manual contains all the information necessary for the correct installation,
setup, operation, and maintenance of the instrument. The procedures included in
this manual must be carried out only by suitably trained and qualified personnel.
1.2 Product Safety
The following symbols are used throughout this manual to indicate procedures
that, if not followed correctly, may result in personal injury or damage to
equipment.
WARNING
Alerts the user to a procedure or practice that can result in personal injury,
injury of others, or death if not followed correctly.
CAUTION
Alerts the user to a procedure or practice that can result in damage to the
system or ancillary equipment if not followed correctly.
NOTE
Notes are used to highlight important information that may assist the
reader in carrying out a procedure or understand the text.
1.2.1 Danger from Process
The system may be connected to ducting that contains process particulate (and
other flue gas constituents) hazardous to health. This can take one or more of the
following forms:
•Particulate which is inflammable or explosive
•Particulate which is toxic or in some other way hazardous to health
•Particulate contained within high-temperature gas.
Take Precautionary Measures
Unless process conditions are known to be entirely safe, suitable precautions such
as the use of breathing apparatus or duct purging/detoxifying must be employed
before entry is made into the duct for installation or maintenance purposes. If in
doubt, consult your local Safety Officer and/or local safety procedures and
guidelines.
1.3 Safety Procedures 󱛻󱛼󱛽
Always observe the following safety precautions. Personnel installing, operating,
or maintaining the equipment are responsible for their safety and for the correct
handling and use of the equipment in accordance with the safety instructions
detailed in this manual.

3System Description
3.1 Components
Figure 2: VIEW 370/373 X sensor (with grounding strap).
3.2 Sensor
The VIEW 370 (373) sensor has a metal probe rod mounted to the small ‘B’
enclosure containing the electronic circuitry. The sensor is connected to the
control unit by a cable of up to 1,000m (0.6 mi) in length. For multi-sensor
systems, network spurs must be used to connect the sensors to a network.
In addition, the VIEW 373 also provides long-term data logging.
3.3 Control Unit
The VIEW 370 (373) is powered via an ENVEA control unit (supplying 24V DC).
The sensor can be interfaced with the Standard Controller for a single-channel
Standard system or the multi-channel ProController for an extensible PRO system
(with up to 32 sensor channels) that is flexible and can be configured easily.
The control unit further provides remote automatic control, measurement, as well
as initiating tests to ensure sensor integrity.
The control unit has its own logging capability for process and regulatory
reporting. Data may be downloaded using PC-ME DUST TOOLS, ENVEA’s modular
software suite. For further details on a control unit, refer to the relevant manual
(see page 3).

ENVEA UK Ltd (PC-000855-MA Issue 6, December 2021) 11
3.4 Principle of Operation
Figure 3: Principle of operation –ElectroDynamic®sensors.
The sensor utilizes the proven and reliable ElectroDynamic®Probe Electrification
technology patented by ENVEA, whereby the collision and interaction of particles
with the probe rod (particle impingement) causes a small electrical charge transfer
to occur between the particulate and the probe rod. It is this small electrical
charge that provides the signal that is monitored by the electronics. Provided the
material type remains constant, the signal generated is proportional to the dust
concentration, even if an accumulation of dust forms on the sensor rod.

4Unpacking and Preparation
4.1 Unpacking and Inspection
Carefully unpack the units and retain the packaging to return equipment for
servicing or repair. If the equipment is damaged in any way, return it to ENVEA
(see the reverse of this manual) in its original packaging.
No responsibility for damage resulting from the use of non-approved packaging
will be accepted.
NOTE
Ensure all items and accessories specified are present. If not,
contact ENVEA or your local ENVEA representative.
4.2 Network Layouts
Standard Systems
Connect a single ENVEA sensor directly to a Standard Controller for a standard,
single-channel system.
PRO Systems
Connect multiple sensors to the ProController either using network spurs or by
daisy-chaining the sensors. For medium to large systems, it is best to place the
control unit(s) in the network centre to minimize voltage drop along cable runs.
For large systems, you may need to boost power using a PSU Repeater (power
supply unit; see SYSTEM OPTIONS on page 7 for details).
4.3 Prerequisites and Guidelines
4.3.1 Location Requirements
When selecting a mounting location for the sensor, the following should be
considered for optimum performance.
1. Mount in the longest, straightest, unrestricted duct available.
2. Ensure correct sensor grounding (see the section below).
3. Avoid excessive vibration. Excessive vibration will affect sensor readings.
4. Ambient or radiating temperatures in the vicinity of the mounting location
must not exceed 50 °C (122 °F).
Refer to the Installation Notes (TN004) for more details (see SECTION 1.5.3 on page
3).
4.3.2 Cabling and Cable Routing
Where the network includes a network spur, the two cables between the sensor
and spur and the spur and control unit are of the same type (comprising four
cores with an overall screen, see SECTION 2.4.2 on page 8). When routing cables,
observe the following:
•Ensure the cable sheath fully penetrates the cable entry gland.
•Fit blanking plugs to unused cable entry glands.
•Ensure cable entry glands are tightened to the cable.
