1 INTRODUCTION
The data loggers of the
HD50
series allow indoor monitoring of various physical quanti-
ties. The data loggers are available for the monitoring of:
•
Temperature
•
Humidity
•
Atmospheric pressure
•
Differential pressure
•
Carbon dioxide (CO
2
)
•
Illuminance
•
Particulate Matter (PM1.0, PM2.5, PM4.0, PM10)
The models that measure relative humidity and temperature calculate absolute hu-
midity, Dew Point, wet bulb temperature, mixing ratio and partial vapour pressure.
Models with 4 input channels, with terminal header connections, are available for the
connection of standard analog sensors:
•
Transmitters with 0÷20 or 4÷20 mA current output and -50÷50 mV, 0÷50 mV,
0÷1 V or 0÷10 V voltage output
•
Pt100 / Pt1000 temperature sensors and K, J, T, N, E type thermocouples
•
Sensors with potentiometric output
This allows extending the monitoring capability to countless other quantities, in addi-
tion to those listed above.
The versions with LCD can be equipped with a
custom LCD
(option
L
) or with a
graphic LCD
(option
G
).
Three LEDs on the front panel indicate the status of power supply, LAN/WLAN local
network connection and alarm.
The data loggers can be connected to a local network via the
Wi-Fi
or
Ethernet
inter-
face. The data logger allows the simultaneous operation of two communication proto-
cols: proprietary and
Modbus TCP/IP
. The data logger manages up to 10 “TCP/IP Cli-
ent” simultaneously. If the local network is connected to Internet, the data can be
regularly sent to an
FTP address, to the Cloud and via e-mail .
For each detected quantity, two alarm thresholds can be set by the user. Exceeding a
threshold is signaled acoustically, by means of the internal buzzer, visually, by lighting
the alarm LED on the front panel, and remotely, by sending alarm
e-mails . An alarm
hysteresis and a delay in the generation of the alarm can be configured for each detect-
ed quantity.
Thanks to the integrated web server, you can configure the data logger and view the
real time measurements from any PC, tablet or smartphone connected to the same lo-
cal network of the data logger by simply using a web browser.
The HD35AP-S and HDServer1 PC software allow configuring the data logger, down-
loading the data into a database and viewing the measurements. The HD35AP-S soft-
ware allows connecting one data logger at a time, while the HDServer1 software al-
lows detecting automatically all the data loggers connected to the network and the
simultaneous connection to all the data loggers. The
HD35AP-CFR21
software option
(available with both HD35AP-S and HDServer1) allows the protection of recorded data
and configuration in response to
FDA 21 CFR part 11
recommendations.
The internal clock can be regularly synchronized with a NIST reference server.
