SPU Table
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. |
| TestItemID |
The test item where the sensor was located. |
| Location_X |
Sensor location x coordinate. |
| Location_Y |
Sensor location y coordinate. |
| Location_Z |
Sensor location z coordinate. |
| SPUNo |
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. |
| Channel |
Channel number on the data acquisition card corresponding to SensorName for dynamic data acquisition. There are 64 channels in each card. |
| Cal_2 |
|
| Status |
Binary value. 1 = channel working, 0 = stop collection. |
| SensorType |
Gives information on the sensor type, including sensor units. |
| Comment |
May include specific information about a sensor, including dates for which sensor data are available in the database. |
