Minimal Vibration
For reasons of sensor structure, avoid installing the DT450G in a location exposed to mechanical
vibration at a level greater than 5 m/s

.
Note: It is virtually impossible for vibration to affect the measured value.
l
No Splashes of Rainwater, Direct Sunlight or Abnormal Temperature Rises due
to Heat Radiation from Equipment
The DT450G may be installed outdoors. However, avoid installing the monitor in a location
exposed to direct sunlight or heat radiated from equipment, in order to prevent the temperature of
the main unit’s casing from rising above 45ºC.
Note: The DT450G can be operated within an ambient temperature range of –20ºC to 45ºC.
If the part of the duct assigned for the probe inlet is covered with insulating material that is likely
to contribute to a temperature rise in the casing, remove the insulating material around the probe
inlet in an area approximately 20 cm wide across the inlet.

Example of acceptable mounting
The temperature rise is minimal
because of air ventilation.
Example of unacceptable mounting
The DT450G is affected by heat
radiation from the insulating material.
