1. GENERAL FEATURES

HD32.2 is designed for WBGT (Wet Bulb Globe thermometer temperature) index analysis in presence or absence of solar radiation. The instrument is provided with three inputs for probes with SICRAM module: the probes have an electric circuit that communicates with the instrument; the sensor 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.

2. WORKING PRINCIPLE

Microclimate term means the environmental parameters that influence the thermal exchanges be-

tween the being and the environments inside limited places and that determinate the so-called “thermal well-being”.

The micro-environmental weather factors together with your own job influence a series of your biologic responses connected to well-being situations (Comfort) or thermal uneasiness (Discomfort).

In fact, the human body tries to keep the thermal balance in equilibrium conditions in order to keep the body temperature on optimal values.

HD32.2 detects the following sizes:

• tnw: wet bulb with natural ventilation temperature probe

• tg: globe thermometer temperature

• ta: ambient temperature

It realizes direct measurements with the probes connected to the instrument and it also calculates and directly visualizes WBGT index.

WBGT (Wet Bulb Globe Temperature) - wet bulb and globe thermometer temperature - is one of the indexes used for determining the thermal stress to which is submitted a being in a warm environment. It represents the value, with reference to the metabolic waste connected to a special job, over which the being is in a thermal stress condition. WBGT index combines the temperature measurement of natural ventilation wet bulb t

with the Glob thermometer tg and, in some situations,

with the air temperature ta. The formula for the calculation is the following one:

• inside and outside the buildings in absence of solar irradiation:

WBGT

close environments

= 0,7 tnw + 0,3 t

• outside the building in presence of solar irradiation:

WBGT

external environments

= 0,7 tnw + 0,2 tg + 0,1 t

where:

= natural ventilation wet bulb temperature

= globe thermometer temperature;

= air temperature.

The detected data must be compared with the limit values established by the regulation; if they are over passed, it’s necessary to:

• directly decrease the thermal stress in the considered working place;

• go on with a detailed analysis of the thermal stress.

In the following table are indicated the limit values of the WBGT thermal stress index taken from ISO 7243 regulation:

To calculate WBGT index, it’s necessary that to the instrument are connected:

• HP3201.2 or HP3201 temperature probe with natural ventilation wet bulb.

• TP3276.2 or TP3275 globe thermometer.

• TP3207.2 or TP3207 wet bulb temperature probe if the detection is made in presence

of solar irradiation.

To measure WBGT index consider the following regulations:

• ISO 7726

• ISO 7243

Measurement

In the place where you want to measure, you must assembly the tripod and the probes necessary for the measurement. You set the instrument up and then you start measuring. If the measurement has to be done in other places, you have to move all the equipment in the new measurement position.

At the end of the measurement or after some times, the acquired data are transferred to the PC for the elaboration and to allow writing the measurement report/s.

6.1 Instruction, accuracy and maintenance of the probes

• Don’t expose the probe to gas or liquids that could corrode the probe material. After the meas-

urement clean accurately the probes.

• Don’t fold the connector, using force upwards or downwards.

• Respect the correct probe polarity.

• During the insertion of the probe’s connector into the instrument, don’t fold or use force against

the contacts.

• Don’t fold the probes and don’t distort them or let them fall: they can damage in an irreparable

manner.

• Use a probe suitable to the measurement type that you want to realize.

• For a reliable measurement, avoid too speed temperature variations.

• Some sensors aren’t isolated with referent to the external sheathing, pay attention not

to be in contact with items under tension (up to 48V): it could be dangerous for the instrument and for the operator who can be electrocute.

• Avoid measuring in presence of high-frequency sources, microwave or great magnetic fields,

because they will be not so reliable.

• The instrument is water-proof, you don't dip it into the water. If it falls into the water, check

that there isn't any infiltration.

7. SERIAL AND USB INTERFACES

HD32.2 has a RS-232C serial interface, galvanically isolated and it has a USB 2.0 interface. As an

optional, we can supply, under request:

• serial connection cable (code HD2110/RS) with M12 connector from instrument side and

9-pole female connector sub D from the PC side.

• serial connection cable (code HD2110/USB) with M12 connector from instrument side and

USB 2.0 connector from the PC side. The USB connection requests the preventive installation of a driver inserted into the instrument software. Before connecting USB cable to the PC, install the driver (see the details contained in the chapter 8.2 Connection to USB 2.0 serial port).

The instrument standard RS232 serial transmission parameters are:

• Baud rate 38400 baud

• Parity None

• N. bit 8

• Stop bit 1

• Protocol Xon / Xoff.

It’s possible to change the speed of RS232C serial data transmission acting on “Selection of serial transfer speed (Baud Rate)” inside the menu (see the menu of the chapter 5.3.1 Baud Rate). The

possible values are: 38400, 19200, 9600, 4800, 2400, 1200. The other transmission parameters are fixed. USB 2.0 connection doesn’t request the setting of any parameter.

The port selection is directly done by the instrument: if USB port is connected to a PC, RS232 serial port is automatically excluded and vice versa.

The instruments are provided with a complete set of commands and data request to send by PC.

All the commands transmitted to the instrument must have the following structure:

XXCR where: XX is the command code and CR is the Carriage Return (ASCII 0D). The command characters XX are only capital, the instrument responses with "&" if the com-

mand is correct, with “?” for each characters combination that is wrong. The response string of the instrument is finished, entering CR (Carriage Return) and LF (Line Feed) commands. Before entering the commands to the instrument through the serial port, we suggest you to block the keyboard to avoid working conflicts: use P0 command. At the end of the process, restore the keyboard use with P1 command.

7.1 THE DATA MEMORIZATION AND THE DATA TRANSFER TO A PC

HD32.2 can be connected to RS232C serial port or USB port of a PC and can exchange data and in-

formation through DeltaLog10 software that works with Windows. The values measured at the inlets of the instrument by Logging (MEM key) function. The memorized data can be transferred to the PC in a second time.

7.1.1 Logging function

Logging function allows memorizing the measurements detected by the probes connected to the inlets. The interval between two following measurements can be set between 15 seconds and 1 hour. The memorization start is obtained pressing MEM key; the stop is obtained pressing the same key: so, the memorized data are a continuous block of data. See the menu headings description in the chapter 5. MEIN MENU". If the Self Shut-off option is activated between two memorizations (see the paragraph 5.22 Self Shut- off mode), pressing MEM key, the instrument memorizes the first data and the switches off, 15 seconds before the following memorization istant, the instrument switches on to acquired the new sample and then it switches off. The memorized data can be transferred to the PC with the command (see the paragraph 5.22 Log File Manager). During the data transfer, the display visualizas DUMP writing; to stop the data transfer, press ESC key on the instrument or on the PC.

7.1.2 Erase function: cancellation of the memorized data

To cancel the content of the memory, you must use Erase Log function (see the paragraph 5.2.5 Log file Manager). The instrument cancels the internal memory and, at the end of the operation, goes back to the normal visualization.

NOTES:

• The data transfer doesn’t involve the memory cancellation: it’s possible to repeat over and over

the transfer process.

• The memorized data independently remain in memory from the batteries charge condition.

• To print the data using a printer provided with a parallel interface, it's necessary to use a serial- parallel

converter (usually, not supplied).

• The direct connection between the instrument and the printer with USB connection doesn’t

work.

• During logging, some keys are disabled, MEM, MENU, ENTER and ESC are enabled.

• Pressing MEM and MENU keys, doesn’t involve the memorized data if these keys are pressed

after starting the memorization, vice versa it’s valid what indicated below.

7.1.3 Print function

Pressing ENTER key, in real time, you can immediately send the detected data by the instrument to RS232C or USB ports. The measurement units of the printed data are the ones visualized on the display. The function starts, pressing ENTER key. The interval between the two following printings can be set between 15 seconds and 1 hour (see Print interval menu heading at the paragraph

5.3.2. Print Interval). If the printing interval is equal to 0, pressing ENTER, key you send only a data to the device. If the printing interval is more than 0, the data sending goes on till the operator doesn’t stop it, pressing ENTER key again.

NOTE: During baud-rate setting, check the printing speed capacity of the used printer.
