Humidity Sensors are composed of a solid state capacitive element
with a linear amplifier. The humidity sensor output is 4-20 mA with
a three wire configuration. The humidity sensor is mounted on a 25'
marine grade cable.
The electronics are completely encapsulated in marine grade epoxy
with a stainless steel housing. The optional solar shield is a ventilated
sun shield with high reflectiveness, low heat retention and low
thermoconductivity. The unit is designed to protect the humidity and
temperature sensor from direct sunlight which may affect the sensor's
4-20 mA output.
