Detail Delta Ohm HD 2070 Vibration Analyzer Hand Arm And Wole Body

Vibration Analyzer HWB HD 2070 merek Delta ohm Main Feature: • Octave and third octave filters, available as option ( HD2070.O1) , satisfy class 1 specifications of IEC 61260 standard. • The HD2070 detects accelerations on three axes with integrated amplifying electronics ( IEPE or equivalent type) ; it is possible to connect three singleaxes or one tri-axial accelerometer to the instrument. Accelerometers with integrate electronics allow to achieve low impedance and low noise connections between the accelerometer and the instrument, decreasing the probability to get wrong or altered measurements because of interferences or electromagnetic disturbances. • The HD2070 analyzes the signals coming from the accelerometer and makes calculations simultaneously on three axes; it calculates the weighted acceleration values as well as the octave or third octave spectra ( with option HD2070.O1) . Acceleration, velocity or displacement values can be shown for each frequency band. Frequency weightings can be freely chosen according to the specific application. • Together with values of instantaneous and mean acceleration, the analyzer calculates in addition peak levels, vibration dose ( VDV) , crest factors and performs statistical analysis ( option HD2070.O2) . • As statistical analyzer, the HD2070 calculates, with option HD2070.O2, the probability distribution of a measurement parameter in 1dB classes. Both the probability distribution and the percentile levels from L1 to L99 are available as graphs. • A versatile data logging function stores multiple profiles and spectra using either the internal memory of 8MB or memory card ( MMC or SD cards up to 2GB) . Each record can be documented with a voice comment. In addition, the HD2070 can be used as an audio recorder, as a further opportunity to document the measures. • With the option HD2070.O3 you can add to the profiles also the signals provided by accelerometers, recording the digital samples directly. When the stored data are analyzed, it is useful to examine the accelerometer signals to verify the absence of artefacts such as, for example, those associated with the phenomenon of DC-shift. • The “ Navigator” program available in the analyzer allows to examine logged measurements and to hear vocal comments. • For a quick setup of the instrument it is possible to store up to nine setup, user-customized according to specific applications. The desired setup is easily identified by the associated title. • The calibration can be performed using either the calibration data of the accelerometers with a vibration generator. The last 120 calibrations performed are recorded in a file and stored in a protected and reserved area of the permanent memory of the instrument. The program interface Noise Studio automatically adds the file supplied with the calibration measurements during the downloading of data into the PC memory. • HD2070 can be completely controlled by a PC, via RS232 and USB serial interfaces, using a special communication protocol. Applications The HD2070 analyzer is able to perform all the measures required by the European regulations 2002/ 44/ EC concerning workers protection from mechanical vibration at the work place. The choice of hand-arm measurements ( HA) or whole body ( WB and BV) changes the frequency range of the spectral analysis available with the option HD2070.O1. For hand-arm measures the range extends from 3.15Hz up to 3.15kHz ( from 4Hz to 2kHz for octave band spectrum) , while for whole body measures the range of central frequencies is shifted towards low frequencies, from 0.5Hz up to 315Hz ( from 0.5Hz to 250Hz for octave band spectrum) . The HD2070 is suitable for the evaluation of worker exposure to vibration and the risk of injury in the following cases: • vibrations transmitted to the hand-arm system by vibrating tools or objects subject to vibration or impact, • whole-body vibration transmitted through the driver’ s seat of vehicles, • whole-body vibration in workstations, • Whole-body vibration of buildings subject to vibration or impact. Technical specifications Technical standards • ISO 8041: 2005 • ISO 5349-1: 2001 ( hand-arm transmitted vibrations) • ISO 2631-1, 2, 4 and 5 1997 ( whole body vibration) • IEC 61260 : 1995 class 1 ( option HD2070.O1) Measurement mode: • HA: Vibrations transmitted to the hand-arm system • WB: Vibrations transmitted to the whole body • BV: Vibrations in buildings.
