WEATHER STATION
Model 100-1950
1.0
GENERAL DESCRIPTION
NovaLynx Corporation provides a weather station, Model 100 -1950, that displays Wind
Speed, Wind Direction, Temperature, Relative Humidity, and Barometric Pressure. The
weather displays are analog dials that are enclosed in an attractive wood frame suitable
for hanging on a wall.
1.1
Wind Speed and Direction
The Wind Speed and Wind Direction indicators are rectangular electrical meters with
needles that deflect with the changing winds. A combination anemometer and vane wind
sensor is mounted outdoors at an elevation that will give good exposure to the local winds.
The wind sensor is connected to a signal conditioning circuit board located behind the
meter case. The anemometer circuit is self generating while the vane circuit requires an
external power supply.
1.2
Temperature
The other meters are mechanical devices. The temperature dial is connected to a
remotely located temperature sensor through a capillary tube. The temperature measured
at the end of the tube is indicated by the meter. The remote temperature sensor may be
located to measure either indoor or outdoor air temperatures.
1.3
Relative Humidity
The relative humidity dial is a self-contained meter with the sensing element housed inside
the meter. As the relative humidity changes, the meter will respond and its pointer will
indicate the new value.
1.4
Barometric Pressure
Similarly, the barometer dial contains the sensing element and indicates changes in the
atmospheric pressure. A moveable set-point needle allows the operator to determine
whether the barometer has risen or fallen since the last reading has been taken.
