Basic description
The Hydro-Logger H40 is
characterized by its robust
mechanical design, small size
and modern electronic circuit
concept with very low self-cur-
rent consumption. It is suitable
for direct use in outdoor envi-
ronments as well as in perma-
nently wet environments in
waterworks.
The H40 station allows you to
set up to 8 recording channels
K1 - K8 for measuring se-
lected physical quantities and 8 binary channels B1 - B8 for recording states on binary
inputs.
In addition to the recording and binary channels, the station contains 7 control channels
K9 - K15 for recording the battery supply voltage, remaining battery capacity expressed
in %, current drawn by the connected sensors during measurement, temperature and
humidity inside the instrument.
The data memory can hold up to 400,000 values including date and time of acquisition.
The capacity of the data memory is sufficient for several years of data recording in nor-
mal operation. When the memory is full, the oldest stored values are gradually overwrit-
ten. The data memory also records extraordinary events - receipt or sending of SMS,
occurrence of an input error, data transfer to the server, etc.
The H40 operates in a power saving mode, in which the instrument is hibernated most
of the time and only wakes up and takes measurements at the set archiving interval.
During the measurement period, power is supplied to the connected sensors and trans-
ducers. The magnitude of the supply voltage is adjustable from 6 to 15 VDC.
The H40G telemetry station transmits the measured values via GSM/GPRS communi-
cation to a database server. In addition, the station can send warning or informative SMS
and receive query or control SMS. Parameter settings can also be changed and FW
upgrades can be performed via GSM/GPRS data communication.
All H40 station parameters are set via the MOST program. Parameters can be changed
from a PC (laptop) via a cable connection or remotely via a web browser and data server.
A 3.6V/19 Ah (H40D) or 3.6V/28 Ah (H40G) lithium battery pack is used to power the
unit, with a connector for easy field replacement. This battery pack allows many years
of operation of the instrument with daily transmission of measured data to the server via
GSM/GPRS network. Unlike the H1, H7 or M4016 stations, the H40 station is not
adapted for external power supply connection.
