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.
It is available in version HD32.35 – HD 32.36 outdoor-box for complete weather station acquisition system.
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:
- Basic version: the communication with the PC for data transfer or programming is done via cable connection.
- Version 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.
- Version 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.
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.
