There are potential-free contact alarm outputs and digital alarm outputs. The outputs are
activated if the values measured by sensors connected to data loggers exceed the programmed
thresholds. The data logger is able to store and report error conditions caused by malfunction
of the connected sensors, hardware or data logger during acquisition and storage. The alarm
outputs can also be programmed to detect such errors.
The instrument is particularly suitable for use in weather stations, for the detection and remote
transmission of climatic variables. Delta Ohm manufactures a wide range of sensors for
measuring environmental variables that can be connected to the data logger, including sensors
for measuring temperature, humidity, barometric pressure, wind speed, solar radiation,
amount of rainfall, etc.
The data logger can be supplied with a program of measures and stores pre-installed according
to specifications of the customer, in order to be operational immediately after installation of the
system. The program is installed directly from Delta Ohm to meet the required specifications
when ordering. Some features of the data logger are password protected (Clock Setup, User
Code Setup, Send Program, GSM Setup). If needed the password is entered by the user at the
time of connection.
Power supply from 12 to 30 Vdc. The system can also be powered by a solar panel and backup
battery of adequate capacity, allowing for installation in remote sites without electrical power.
An internal lithium battery keeps the date and time of the instrument in the absence of external
power. The data logger can provide power to all sensors connected at its terminals. It can signal
and store when the supply voltage is below a programmable threshold and go into wait (standby)
mode to low power consumption. In this mode, the datalogger interrupts the power supply to
all sensors and suspends acquisitions/loggings, until the supply voltage returns at least to the
minimum threshold.
Technical characteristics
HD 32MT.1
METEO DATA LOGGER
The HD32MT.1 is a data logger capable of capturing and logging the values measured by a
series of sensors connected to its inputs.
The data logger is completely programmable by the user and is therefore very versatile. The
supplied HD32MTLogger application software, supplied with the instrument, allows simple
and intuitive programming by using graphic interfaces, without the need of learning any
programming language, thus minimizing the time needed to make the system operational.
The values recorded by the instrument can be transferred to a PC by using the HD32MTLogger
software. The data logger can be configured to memorize the instant value, the minimum value,
the maximum value, the average value and the standard deviation of the measurements. For
measurements that require the counting of pulses, the total counted pulses can be stored.
Different acquisition/recording intervals can be programmed per each input. Each recording
includes acquisition date and time
The data logger has a “flash” internal memory arranged in circular mode: when the memory
is full the new data overwrite the older ones. The number of storable measurements depends
on the number of sensors employed, on the type of measurement to be stored and on the fact
that the sensors are acquired all at the same time or at different instants. For example, with 8
sensors captured at the same time, 100,000 records can be stored, each one composed of 8
instantaneous measurements.
Data can also be directly recorded to a removable SD-type memory card with a capacity of
4 GB. The use of a memory card allows extending the memory capacity of the instrument,
allowing not to loose the data when the memory is full.
Three data logger versions are available, according to the possibility of communication with
the PC:
tBasic version: the communication with the PC for data transfer or programming is done
via cable connection.
tVersion with Radio Modem option: in addition to the direct cable connection to your PC,
you can transfer the data and program by VHF radio using optional external radio modems.
tVersion with TCP/IP option: data transfer and programming can be done via TCP/IP via
optional external Ethernet Serial Server.
All versions can be equipped with an optional GSM module to be connected externally to the
instrument, through which you can send alarm SMS to mobile phones and send the recorded
data by e-mail or to an FTP address.
The instrument can be connected to the most common sensors used in industrial and
environmental fields, with both analog and digital output.
The typical sensors that can be connected to the instrument are:

Description of terminals
Display
It is possible to connect an optional LCD display to the data logger, to check the values
acquired by the data logger without having to connect your PC.
The display is available in the basic version (HD32.D), or with the GPS option (HD32.D.GPS) to
automatically update the clock of the data logger. The displays are designed for being fixed to
the outdoor housings HD32.35, HD32.35FP, HD32.36 and HD32.36FP.
The display is backlit and connects to the data logger COM PC RS232 serial port. The supply
voltage required by the display is 8...30 Vdc.
1. Power input PWR 12…30 Vdc.
2. Switched power supply output +Vsw. With the same value of the power input, but active
only during acquisition of measurements.
3. Regulated power supply output +5V.
4. Inputs for analogue signals. Divided into 8 channels corresponding to 8 differential inputs
(BIP channels) or 16 single-ended inputs (UNI channels). The differential input number is
shown in white to the left of the terminals.
Each channel is composed of four terminals:
Terminal E: Excitation voltage. Used only in certain measurement configurations.
Terminal H: If the channel is used as a differential input, it corresponds to the “+” connection
of the input signal. If the channel is used for single-ended inputs, it corresponds
to the “+” connection of the input signal of the single-ended channel with the
number indicated in yellow to the left of the terminal.
Terminal L: If the channel is used as a differential input, it corresponds to the “—”
connection of the input signal. If the channel is used for single-ended inputs,
it corresponds to the “+” connection of the input signal of the single-ended
channel with the number indicated in yellow to the left of the terminal.
Terminal G: Analog ground. It has the same potential of the power supply ground. If the
channel is used for single-ended inputs, it corresponds to the “—” connection
of the input signal.
5. Terminal for ground protection.
6. Digital input/output channels. 8 channels are available, each one usable as input for
connection of sensors with ON/OFF digital output, or as alarm outputs.
7. Not used.
8. PULSE inputs for high frequency pulse counting Two inputs are available, marked with
P1 and P2.
9. Insulated inputs SW IN for number of voltage-free contacts opening/closing count. Two
inputs are available, marked with 1 and 2.
10. Voltage-free contact alarm outputs. Two outputs are available, marked with 1 and 2.
11. RS485 serial port for the connection of anemometers series HD2003 and HD52.3D…, and
sensors with MODBUS-RTU protocol.
The connection to the RS485 port of sensors other than those indicated may not
work properly due to a different communication protocol.
12. Memory card reader.
13. RS232 serial port COM PC, for direct connection to the PC or for connection of the optional
Radio Modem (Radio Modem version) or of the optional Ethernet module.
14. RS232 serial port COM AUX for connection of the optional GSM module.

Connection of the display
For each measurement is displayed: the name of the parameter measured, the value of the
measure, the unit of measurement, the data logger input the sensor is connected to, the
acquisition interval and the current UTC time in the data logger.
The various measures are automatically scrolled on the display, or alternatively can be scrolled
manually.
Data communication
There are different ways to communicate the stored data to the PC:
direct cable communication;
!"communication via VHF radio modem (radio modem version only);
!"communication via a Local Area Network (LAN) with TCP/IP protocol (an optional RS232/
Ethernet module is required);
!"communication via the GSM network (only if the optional GSM module is present).
The communications via VHF Radio Modem and GSM module are especially useful for
installations in remote unattended areas
Via the GSM connection, the data logger is capable of sending alarm messages via SMS to
mobile phones, and stored data via Internet to e-mail and FTP addresses. In the GSM module
must be inserted a SIM card enabled for data transmission, to be obtained from a telephone
operator that has a suitable GSM network coverage in the place where the system will be
installed.
