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
•
Carbon dioxide (CO
2
)
•
Illuminance
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
.
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 de-
tected 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 PC software
HD35AP-S
allows configuring the data logger, viewing the real time
measurements, downloading and viewing the data into a database. The HD35AP-S
software allows connecting one data logger at a time. If there are several data loggers
of the HD50 series in the local network, the PC software
HDServer1
allows detecting
automatically all the data loggers connected to the network and the simultaneous
connection to all the data loggers, entering the data received by the data loggers into
a database, viewing the data in the database and configuring some basic parameters
of the devices (alarms, logging interval, …). 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.
