1. GENERAL FEATURES
HD32.2 is designed for WBGT (Wet Bulb Globe thermometer temperature) index analysis in pres-
ence or absence of solar radiation. The instrument is provided with three inputs for probes with SI-
CRAM module: the probes have an electric circuit that communicates with the instrument; the sen-
sor calibration data are saved in its permanent memory.
All the SICRAM probes can be inserted in one of the inputs: they are automatically recognized
when you switch the instrument on.
The
main features of the instrument are:
•
Logging: acquisition and memorization of data inside the instrument. Memory capacity: 64
different logging sections, with the possibility to set the acquisition interval of the samples.
You can set the duration of the memorization and, with auto-start function; it’s possible
to set the starting and finishing date and the hour of data memorization.
•
The measurement unit of the temperature visualized sizes: °C, °F, °K.
•
The system date and hour .
•
The visualization of the maximum, minimum and medium statistic parameters and their
cancellation.
•
The transfer speed of the data through the serial port RS232.
NOTE: The set acquisition interval is the same for all the probes connected to the instrument.
HD32.2 instrument can contemporarily detect the following sizes:
•
Globe thermometer temperature Tg .
•
Wet bulb with natural ventilation temperature Tn .
•
Ambient temperature T.
On the basis of the detected measurements, HD32.2 can calculate:
•
WBGT(in) index (Wet Bulb Glob Temperature: wet bulb and globe thermometer tempera-
ture) in presence or absence of solar irradiation.
•
WBGT(out) index (Wet Bulb Glob Temperature: wet bulb and globe thermometer tempera-
ture) in presence of solar irradiation.
