III. Sensor Mounting
When deciding the sensor mounting location, please keep in mind the following recommendations:
1. Choose a well-ventilated area remote from wet surfaces. A sensor located near the deck
will detect water evaporation from the wet deck in wet weather. A sensor located in a locker
measures the humidity of the air in the locker, but not outside air humidity.
2. Do not place the sensor in direct sunlight. Heating the sensor causes error in humidity
and temperature measurements both.
3. To prevent the sensor from being heated by the boat itself, minimize the area of contact between
the sensor case and other surfaces, use materials with low thermal conductivity (plastic)
to isolate the sensor case from metal surfaces or surfaces that can be heated from inside
or from other parts of the boat.
4. Do not place the sensor where it can be flooded by water, gets wet in the rain or sprayed with water.
In this case the sensor will measure the drop of water on it.
5. The sensor has a solid metal body protected with resin, but membrane at its end has a plastic
housing. Avoid places where the sensor may be exposed to accidental impact.
6. The sensor should be placed vertically with the membrane end pointing toward the deck,
which is usually more protected from condensation drops or occasional water spray.
7. The minimum outer diameter of the wire is 30mm when being bent.
The following places may be a good mounting locations:
1. Under the cockpit table on sailing yachts.
2. Under the standing shelter on catamarans and motor boats.
You can affix a sensor with the pads supplied and plastic clamps as shown in Figure 1.
