Replacement Temperature/RH sensor
Blank Sensor Installation/Calibration Form
Blank Sensor Calibration Metadata Form
The sensor head should be recalibrated every year. Figure 6 illustrates how the replacement and
recalibration schedule should work. Note that there is a lag the first year the sensors are installed.
Sensor 1 is removed after a year of operation, but since two sensors need to be running at a time,
Sensor 2 is not removed until after Sensor 1 is recalibrated and returned to the field. Follow the
steps below for removing and replacing sensors. Use a Sensor Installation/Calibration Form
(Appendix A.4. Sensor Installation/Calibration Form) to record the event.
1. Detach the sensor housing of the radiation shield. Unhook the bottom portion of the
radiation shield from the top by loosening the four clamps that retain the housing to the
rest of the shield. Do not disconnect the sensor cable or power cable coming from the
shield.
2. Remove the sensor head. Unhook one of the temperature sensors and pull it out of the
housing without disconnecting the cables from the sensor to the cabling box. Once the
sensor is out, pull out the sensor head at the end.
3. Replace the sensor head. Write down the serial number of the replacement sensor head
in the Sensor Installation/Calibration Form (Appendix A.4). Insert the replacement head
into the probe (there is only one way to do it).
4. Put back everything in place. Put the probe back in the radiation shield housing making
sure that the two sensor heads are not touching each other. Clamp back the sensor
housing tube into the fan housing section of the shield.
5. Send the sensor head out for calibration. Complete a Sensor Calibration Metadata
Form (Appendix A.5) for each sensor that is sent out for calibration. Obtain an RMA
number from the closest regional Campbell Scientific office and mail the sensor head out.
When the sensor comes back, fill the rest of the Sensor Calibration Metadata Form and
keep the sensor as a duplicate. Repeat the process above a year later when the other
sensor in the pair will need to be recalibrated.
6. Submit the information to the TEAM portal. The information on the Sensor
Installation/Calibration Form should be always be submitted to the TEAM portal (see
Section 4.10). When a sensor is sent out for calibration, also submit the information from
the Sensor Calibration Metadata Form to the TEAM portal (Section 0 as well).
