Sensor Specifications
Wind Speed |
|
Units of Measure: | mph | kt | B | m/s | ft/min / km/h |
Specification Range: |
|
Operational Range: |
|
Resolution: |
|
Accuracy (+/-): | Larger of 3% of reading, least significant digit or 20 ft/min |
Notes: | 1 inch|25 mm diameter impeller with precision axle and low-friction Zytel® bearings. Startup speed stated as lower limit, readings may be taken down to 0.4 m/s | 79 ft/min | 1.5 km/h | .9 mph | .8 kt after impeller startup. Off-axis accuracy -1% @ 5º off-axis; -2% @ 10º; -3% @ 15º. Calibration drift < 1% after 100 hours use at 16 MPH | 7 m/s. Replacement impeller (PN-0801) field installs without tools (US Patent 5,783,753). Wind speed calibration and testing should be done with triangle on impeller located at the top front face of the Kestrel. *F/S only in Ballistics units. Beaufort not available in Ballistics units. |
Ambient Temperature |
|
Units of Measure: | Fahrenheit, Celsius |
Specification Range: |
|
Operational Range: |
|
Resolution: |
|
Accuracy (+/-): |
|
Notes: | Hermetically sealed, precision thermistor mounted externally and thermally isolated (US Patent 5,939,645) for rapid response. Airflow of 2.2 mph|1 m/s or greater provides fastest response and reduction of insolation effect. Calibration drift negligible. Thermistor may also be used to measure temperature of water or snow by submerging thermistor portion into material -- remove impeller prior to taking submerged measurements and ensure humidity sensor membrane is free of liquid water prior to taking humidity-based measurements after submersion. |
Pressure |
|
Units of Measure: | inHg, hPA, mb |
Specification Range: |
|
Operational Range: |
|
Resolution: |
|
Accuracy (+/-): |
|
Notes: | Monolithic silicon piezo-resistive pressure sensor with second-order temperature correction. Between 1100–1600 mbar, unit will operate with reduced accuracy. Sensor may not operate above 1600 mbar and can be damaged above 6,000 mbar or below 10 mbar. Calibration drift is negligible for the life of the product. |
Relative Humidity |
|
Units of Measure: | % |
Specification Range: | 5 to 95% 25°C non-condensing |
Operational Range: | 0 to 100% |
Resolution: | 0.1 %RH |
Accuracy (+/-): | 3%RH |
Notes: | To achieve stated accuracy, unit must be permitted to equilibrate to external temperature when exposed to large, rapid temperature changes and be kept out of direct sunlight. Calibration drift is typically less than ±0.25% per year. |
