Tachometer-
Synchronized Measurements |
The analyzer
can use the tachometer input to synchronously sample and average data. These data contain
phase information for vibration related to the tachometer. The analyzer can report phase
to +/-3 degrees for this vibration, which is reproducible to 1 degree. |

Unconditioned
Tachometer
Input |
Tachometer
signal processing electronics are capable of adjusting the full-scale input range to
handle any available sensor for measuring speed. Adjustment of the tachometer conditioning
electronics is performed automatically by the microprocessor and requires no user
intervention. The voltage level that is used as a reference for detection of the start of
the revolution can be adjusted from 120mV to 5 volts. The tachometer circuitry can detect
speeds up to 10.000 RPM. |
|
|
| Autoranging Input |
The
analyzer autoranges all signal inputs based on sensor sensitivity. That way, it can
determine the optimum gain setting to achieve the maximum dynamic range. Gains are
adjusted by factors of two (1 to 512) for all channels. This adjustment enables the
analyzer to perform each measurement without overload and with maximum accuracy. |
|
|
| Sensor Types |
The
analyzer will accept any vibration signal input (acceleration, velocity, or displacement).
The input is then displayed as collected or integrated to another vibration unit. The
vibration input will accept any voltage-generating sensor (must have external charge
converter when required). |
|
|
| Analysis Range |
Data is
accurately transformed from the time to frequency domain using a high roll-off, 8-pole
elliptical, anti-aliasing filter with a Fast Fourier Transformer (FFT). The analyzer will
perform FFT resolutions of 100, 200, 400, and 800 lines.
