HD2070 is a portable vibration analyzer performing optional spectral and statistical analysis on three 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.
The HD2070 analyses accelerometer signals and makes calculations simultaneously on three axes.
The instrument calculates, in parallel for all the measurement channels, weighted acceleration values and 1/1 or 1/3 octave spectra (option HD2070.01 “spectral analysis”)
Acceleration, velocity or displacement values can be shown for each frequency band. 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 HD2070.02 “statistical analysis”)
HD2070 has been designed combining maximum flexibility and ease of use with the possibility to update the instrument according to the evolution of regulations concerning vibrations. The user can directly update the instrument firmware by means.
The HD2070 vibration analyzer detects accelerations on three axes through allow using standard cables to achieve low impedance and low noise connections between the accelerometer and the instrument, simplifying its use and decreasing the probability to get wrong or altered measurements, because of interferences or electromagnetic disturbances.
Instrument for the Analysis of the Indices: WBGT, PMV, PPD
HD32.3 – WBGT – PMV Index is an instrument made by Delta Ohm Srl for:
– Analysis of hot environments using WBGT index (Wet Bulb Glob Temperature: wet bulb temperature and Globe thermometer) in presence or absence of solar radiation
– Analysis of the moderate warm environments using PMV index (Predicted Mean Vote) and PPD index (Predicted Percentage of Dissatis ed)
The Sunshine Duration sensor LP SD18 measures sunshine status and duration. The WMO (World Meteorological Organization) defines the sunshine duration as the time during which the direct solar radiation exceeds the level of 120 W/m2.
The LP Silicon-PYRA 04. pyranometer measures the global solar radiation (W/ m2) by using a silicon photodiode (350nm-1100nm). The special geometry and the diffuser allow to have a pyranometer field of view of 180 degrees according to cosine law.
