Accelerometer & related products FAQ
When the sensor sensitivity is [0.9 mV/(m/s2)] and the gain setting of the PS-1300 is [10];
Measureable maximum acceleration, speed and displacement
(When the sensor with 1 mV/(m/s2) sensitivity.)
In case of acceleration (ACC m/s2)
| Gain | 1 | 2 | 5 | 10 | 20 | 50 | 100 |
|---|---|---|---|---|---|---|---|
| Maximum acceleration(m/s2) | 5000 | 2500 | 1000 | 500 | 250 | 100 | 50 |
In case of speed (VEL mm/s)
| Gain | 1 | 2 | 5 | 10 | 20 | 50 | 100 |
|---|---|---|---|---|---|---|---|
| Maximum Speed(mm/s) | 5000 | 2500 | 1000 | 500 | 250 | 100 | 50 |
In case of displacement (DISP mm)
| Gain | 0.1 | 0.2 | 0.5 | 1 | 2 | 5 | 10 |
|---|---|---|---|---|---|---|---|
| Maximum displacement(mm) | 500 | 250 | 100 | 50 | 25 | 10 | 5 |
In case of other than the sensor with 1 mV/(m/s2) sensitivity is used, please check with the following formula before use.
|
From the above formula;
V/EU setting value = Sensor sensitivity × 5 ÷ The maximum displacement value in the above formula which can be obtained by the gain setting (sensor sensitivity: the value of mV/(m/s2))
The actual settings for the above example;
Set the unit [mm] and physical quantity [0.9 V/EU] by the input menu [Unit/ Calibration] of the DS-0221. Setting for the speed is the same, but the unit is [mm/s].
In addition, these calibration methods are same for other FFT Analyzers such as CF-7200.
