SPU
Contains information about the dynamic sensors, including sensor type and location. (SPU refers to the 6 signal processing units, which acquire the dynamic sensor data.)
| SensorID |
Sequential number used for sensor identification |
| SensorName |
Name assigned to the sensor. The first letters identify the sensor type: VD = vertical displacement; EG = embedded (strain) gage. |
| SensorType |
Gives information on the sensor type, including sensor units. |
| Unit |
|
| TestItemID |
The test item where the sensor was located. Refer to the test area diagram. |
| LocationX_ft |
Sensor location x coordinate (feet). Refer to the test area diagram. |
| LocationY_ft |
Sensor location y coordinate (feet). Refer to the test area diagram. |
| LocationZ_in |
Sensor location z coordinate (inches). Refer to the test area diagram. |
| SPU |
Number of the signal processing unit (SPU) used to acquire dynamic data from SensorName. SPUs are numbered 1 – 6. |
| Card |
Data acquisition card within the SPU used to acquire data from SensorName. There are two acquisition cards in each SPU. |
| CalFactorA |
Calibration factor A (for software data processing). |
| CalFactorB |
Calibration factor B (for hardware data processing). |
| Comment |
May include specific information about a sensor, including dates for which sensor data are available in the database. |
