History
| Rec No. | Date | Loc From | Title | Loc To | Notes |
|---|---|---|---|---|---|
| 4331 | 2020-01-30 | East Pond Heat Flux Plate A | Disposed | Lost none | In the process of decommissioning the EP tower this heat flux plate was lost when its cable broke off at the plate. |
| 3425 | 2018-04-17 | Lab none | Installed | East Pond Heat Flux Plate A | Installed at EP tower as part of initial site set up in profile A (north) and mux channel 10 |
| 3337 | 2018-02-27 | Lab none | Repair | Lab none | I soldered on a cable and reinforced the cable-sensor connection with silicone. This sensor tested sufficiently against sn 00245 and sn 10809. |
| 3318 | 2018-01-31 | East End Heat Flux Plate A | Removed | Lab none | Removed from EE because it started changing in steps around the end of October. Needs to be inspected and repaired. There are several nicks in the cable and the cable-head connection is loose. |
| 1705 | 2015-01-20 | Lab none | Installed | East End Heat Flux Plate A | Reinstalled after being removed when the scaffolding fell over. |
| 1690 | 2015-01-05 | East End Heat Flux Plate A | Removed | Lab none | Removed from the site due to the tower falling over in the wind on 2014-12-30. Likely undamaged. |
| 1150 | 2013-11-25 | Lab none | Installed | East End Heat Flux Plate A | Installed about 2cm below the surface to the west of the tower at the Twitchell East End Wetland site. |
| 780 | 2012-09-10 | Lab none | Repair | Lab none | I spliced a new wire on to this SHF plate in preparation for calibration by Sebastian. |
| 639 | 2012-05-17 | Twitchell Rice Heat Flux Plate A | Removed | Lab none | I found this heat flux plate in the field. It had not been removed with the other ground sensors and got cut off by the tractor. |
| 439 | 2011-11-02 | Lab none | Installed | Twitchell Rice Heat Flux Plate A | Installed in the field after harvest and chopping. The cable was replaced due to cracking and the self calibration heater cable was shortened to a pig tail. |
| 438 | 2011-10-27 | Twitchell Rice Heat Flux Plate A | Removed | Lab none | Removed from the field to repair cracking cables in the lab. |
| 1742 | 2009-04-03 | Lab none | Installed | Twitchell Rice Heat Flux Plate A | Installed with the initial set up of the Twitchell Rice tower. |
| 129 | 2001-05-25 | Factory | Calibration | Factory | Initial factory calibration: 61.5 uV/W/m2
Heater resistance: 109.0 Ohm Heater area is 0.003885 m2 |
