4 Environment
The linescanner complies with ingress protection
IP65 and is therefore dust and splash resistant. The linescanner’s
window is made of a material that is resistant to thermal stress.
4.1 Ambient Temperature
Without water cooling, the linescanner is designed for ambient operating temperatures between 0 to 50°C (32 to
122°F). With water cooling, it can be used in environments of up to 180°C (356°F), see section 5.6
Water Cooling ,
page 29. The internal temperature is the determining factor for proper operation of the linescanner. It is displayed
in the DataTemp software. The difference between the external ambient temperature and the temperature inside
the housing also depends on the thermal contact of the linescanner and its mounting hardware.
The temperature inside the housing must be between 0 to 60°C (32 to 140°F) during
operation and never more than 65°C (150°F) at any time, including non-operation!
4.2 Atmospheric Quality
If the window gets dirty, infrared energy will be blocked and the sensor will not measure accurately. It is good
practice to always keep the window clean. The air purge collar helps keep contaminants from building up on the
window, see section 5.7
Air Purge Collar , page 31. 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 sensor installation.
4.3 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.
•
Do not run AC power in the same conduit as the sensor signal wiring.
•
To avoid potential differences use a single power circuit to power both the linescanner and the PC running
the software!
•
To avoid ground loops, make sure that only ONE POINT is earth grounded. Use a single power circuit to
power both the linescanner and the PC running the software!
The housing of the linescanner is electrically grounded. All inputs and outputs are electrically isolated from the
housing, the input voltage, and from one another. The current outputs have a joint ground connection, but are
electrically isolated from any other ground connection.
