TurfWeather Weather Station
3. Maintenance
Proper maintenance of the TurfWeather weather station is essential to obtain
accurate data. Equipment must be in good operating condition, which requires
a program of regular inspection and maintenance. Routine and simple
maintenance can be accomplished by the person in charge of the weather
station. Inspect the weather station weekly when first installed to get an
understanding of how often cleaning and inspecting should be performed. Keep
the weather station level for accurate solar radiation and rain measurements.
Use the level bubble located on top of weather station for reference. More
difficult maintenance such as sensor replacement can be accomplished with
instructions included in this manual, or weather station can be sent to Campbell
Scientific if preferred.
3.1 Solar Panel P/N SP5
An occasional cleaning of the glass on the solar panel will improve its
efficiency. Use warm mildly soapy water and a clean cloth. Rinse with clean
water.
3.2 Battery Pack P/N 14159
The Battery pack is a 12 Volt, 0.8 AHr battery with a special connector. It has
a life expectancy of 3 to 5 years. It is located inside the weather station. It is a
sealed lead acid battery design, and if it is discharged below 11.0 volts it may
become damaged and no longer accept a charge regardless of the age of the
battery. PC200W and most weather software will display the weather station
battery voltage. Typical measurements should be between 12.5 and 13.5 volts.
See Section 3.11 ‘Battery Pack Removal and Replacement Procedure’ for
instructions on replacement.
3.3 Temperature/Relative Humidity sensor P/N 14144
The Temperature/Relative Humidity sensor has a life expectancy of 18 months.
The Relative Humidity measurement will begin to drop off as the sensor ages.
It is located on the bottom of the weather station inside the slotted cylinder
shaped protector. Take care not to expose this sensor to overspray from
pesticides, fertilizers, etc. Use a soft brush to remove dust and cob webs from
sensor area. See Section 3.12 ‘Temperature/Relative Humidity Sensor
Assembly Removal and Replacement Procedure’ for instructions on
replacement.
3.4 Solar Radiation sensor P/N 14009
The Solar Radiation sensor has a life expectancy of approximately 5 years.at an
expected 2% per year degradation rate. This sensor is replaced rather than
recalibrated. It is the small round sensor located on the opposite end from the
wind sensors. Keep this sensor clean using a soft cloth and very mild soapy
water, and follow up with a clean damp cloth with water only. See Section
3.13 ‘Solar Radiation Sensor Removal and Replacement Procedure’ for
instructions on replacement.
