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)
HD32.3 is an instrument for: analysis of hot environments using WBGT index in presence or absence of solar radiation; analysis of the moderate warm environments using PMV index and PPD index.
Reference rules: ISO 7243, ISO 8996, ISO 7726, ISO 7730.
The instrument is provided with three inputs for probes with SICRAM module: the SICRAM module interface between the instrument and sensor connected and communicate the sensor parameters and calibration data to the instrument.
All SICRAM probes can be plugged into any of the inputs: they are automatically recognized upon turning on the instrument.
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.
Delta Ohm manufactures First Class LP PYRA 02 and LP PYRA 12 and Second Class LP PYRA 03 pyranometers which fully comply with ISO 9060 standards, and meet the requirements defined by the World Meteorological Organization (WMO). These are strong and reliable instruments, especially designed to be used under all weather conditions. They are suitable for installation on the field.
The temperature probe TP32MTT.03 is equipped with seven Pt100 1/3 DIN sensors for the measurement of temperature at depth: +5 cm, 0, ‐5 cm, ‐10 cm, ‐20 cm, ‐50 cm, ‐1 m with respect to the soil level, according to the indications of the World Meteoro‐ logical Organization (WMO). The probe TP32MTT.03.1 is equipped with six Pt100 1/3 DIN sensors for the measure‐ ment of temperature at depth: +5 cm, 0, ‐5 cm, ‐10 cm, ‐20 cm, ‐50 cm with respect to the soil level.
