How should the sensor be waterproofed?
Does condensation ever form inside the
metal package of the sensor?
The sensor itself is not waterproof. The following is an
example of how it can be waterproofed.
General waterproofing example
Cover the entire sensor with a box, and use a polyethylene sheet for the front
face. The thickness of the polyethylene sheet should be no more than 0.5
mm. If any thicker, the sensitivity of the sensor will drop by more than half.
In general, no. However, be sure to perform performance and
reliability tests in the operating environment before com-
mencing design.
Dry air is sealed into the metal can package of the sensor, thus there is in
general almost no moisture inside the metal can. However, if the sensor is
to be used outdoors, take sufficient measures for waterproofing and protec-
tion against dust, condensation and freezing.
