| SD-201 | Wind Direction | o from N | 10/02/2001 | - | B5465 B5466 W4384 |
0.072 o/mV |
| The mean wind direction vector at 113, 52, and 3 meters. The standard deviation of the wind directions are also recorded. | ||||||
| SS-201 | Wind Speed | m/s | 10/02/2001 | - | B6417 W4374 W4371 |
0.0440 m/s/pulse+0.2946 m/s 0.0441 m/s/pulse+0.3314 m/s 0.0439 m/s/pulse+0.3090 m/s |
| The mean wind speed at 113, 52, and 3 meters. The peak 5-min gust and standard deviations are also recorded. | ||||||
| RTD | Temperature | oC | 10/02/2001 | - | - | 0.02 oC/mV-50 oC |
| The Temperature Sensor is mounted at 3, 52, and 83 meters. | ||||||
| RTD | Delta Temperature | oC | 10/02/2001 | - | - | 0.0022 oC/mV-4.444 oC |
| The Delta Temperatures are measured by two sensors (different from temperature sensors above): ΔT83m= T83m- T52m and ΔT113m= T113m- T83m |
||||||
| RTD | Dewpoint Temperature | oC | 10/02/2001 | - | - | 0.02 oC/mV-50 oC |
| The Temperature Sensor is mounted at 3, 52, 83, and 113 meters. | ||||||
| ? | Pressure | mBar | 10/02/2001 | - | - | 0.052 mBar/mV+740 mBar |
| The Pressure Transmitter is mounted in the building at 3 meters. | ||||||
| - | CR23X Battery Voltage | V | 10/02/2001 | - | - | - |
| CR21X internal battery voltage. | ||||||
| - | CR23X Temperature | oC | 10/02/2001 | - | - | - |
| CR23X internal temperature. | ||||||
| CSI | Building Temperature | oF | 10/02/2001 | - | 107 | 1.8 oF/mV+32 oF |
| The Temperature Sensor is mounted in the building. | ||||||
| - | UPS Status | mV | 10/02/2001 | - | - | - |
| UPS Status signal; 900 - 1000 mV = Utility Power & UPS Okay; >1000 mV indicates a utility power problem and UPS batteries may be providing power; <900 mV indicates a utility power problem and UPS batteries are NOT providing power. | ||||||
| - | Security | mV | 10/02/2001 | - | - | - |
| Building door security closure switch; 1000 mV +/- 20 = Door Closed. | ||||||
