Vibration Meter HD2030(DELTA OHM)

Vibration-Meter-HD2030HD2030 is a portable vibration analyzer performing spectral and statistical analysis on four channels simultaneously. The instrument measures all parameters required by current regulations concerning workers protection from vibration related risks and is able to measure vibrations transmitted to both hand-arm and whole body.

 

Technical specifications of HD2030

IEC 61260:1995 class 1 (octave and third octave filters)
•     Measurement modes:
Hand-transmitted vibrations
Whole-body vibrations
Building vibrations
•     Measurement parameters:
RMS, VDV, MTVV, Peak, Max, Min
•     Frequency weightings:
Fz, Fc, Wh for hand-transmitted vibrations
Fz, Fa, Wb, Wc, Wd, We, Wj, Wk for whole body vibrations
Fz, Fm, Wm for building vibrations
•     Octave or third octave band spectral analysis:
The range of central frequencies depends on the chosen application according to the following table

Application Central frequency range
Octave Band Third Octave Band
[Hz] [Hz]
Hand-Arm 4 ÷ 2000 3.15 ÷ 3150

Building-Vibration 0.5 ÷ 250 0.315 ÷ 315

•     Statistic Analysis The selected measurement parameter is analyzed in 1dB classes. Both the probability and the percentile graphs can be shown.
•     Measurement range 0.1m/s2 ÷ 7000 m/s2 with accelerometer HD356A02 for hand-arm measurements
•     Linearity range three ranges of 80dB overlapped by 70dB
•     Digital converter Four analog to digital converters with a resolution of 25 bits at 8k samples per second
•     Inherent noise level Less than 30mm/s2 with accelerometer HD356A02 for hand-arm measurements and Wh filter
•    Display Graphic backlit display 128x64 pixels Screens:
VLM1: Three parameters for each measurement axis
VLM2: Three parameters of acceleration vector calculated from the three right channel input axes
VLM3: Three global parameters for each measurement axis
VLM4: Three global parameters of acceleration vector calculated from the three right channel input axes
PROFILE: Graphic profile of one parameter for each measurement axis with integration time programmable from 1s to 1 hour
SPECTRUM: Octave or third octave spectrum for each measurement axis with calculation of one wideband filter. The graph can show the spectrum of acceleration, velocity or displacement.
STATISTICS: the statistical distribution of the parameter chosen in PROFILE
PERCENTILES: Percentile level graph of the parameter chosen in PROFILE.
•     Memory 8MB Internal FLASH type memory and connector for memory card SD type up to 2GB.
