4 Environment
4.1 Ambient Temperature
Without water cooling, the ThermoView camera is designed for ambient operating temperatures between -15 to
50°C (5 to 122°F). With water cooling equipment, it can be used in environments at higher temperatures.
By forcing water circulation, it is possible to maintain cooled internal housing temperatures. It helps to verify the
flow capacity needed and cooling water temperature before proceeding with the installation. It is also necessary to
verify the environmental temperature and install the housing at the correct distance from the heating source.
Note that too cold water can cause condensation, which can lead to damage in the device, see section
9.2
4.2 Atmospheric Quality
If the lens gets dirty, infrared energy will be blocked and the instrument will not measure accurately. It is good
practice to always keep the lens clean. The air purge collar accessory helps keep contaminants from building up
on the lens, see section 7.3.2
, page 54. If you use air purging, make sure a filtered air
supply with clean, dry air at the correct air pressure is installed before proceeding with the installation.
4.3 Protection
The ThermoView camera without any attached add-on lens complies with the international protection standard
IP67. Please note, that the international protection class of IP67 must be downgraded to IP54, if an external add-
on lens is attached. Such lenses are not watertight or splash-
proof and don’t resist harsh environment conditions.
Note that effectiveness against splashing under IP67 is possible only, if terminal caps are in place and all external
connectors are connected and comply to IP67 too. To retain the given IP67 protection class, please inspect
periodically all seals of the waterproof connectors and end caps.
4.4 Electrical Interference
To minimize electrical or electromagnetic interference or noise, please be aware of the following:
•
Mount the instrument as far away as possible from potential sources of electrical interference, such as
motorized equipment, which can produce large step load changes.
•
Use shielded wire for all input and output connections.
•
For additional protection, use conduit for the external connections. Solid conduit is better than flexible
conduit in high-noise environments.
•
To avoid ground loops, make sure that only ONE POINT is earth grounded, either at the instrument or at
the power supply.
Note
When installing the ThermoView camera, check for any high-intensity discharge lamps or heaters that may
be in the field of view (either background or reflected on a shiny target)! Reflected heat sources can cause a
sensor to give erroneous readings.
