IMPORTANT
INFORMATION
PRECISELY MEASURED
instrumentation and monitoring
Operation
Before going to site, a SIM card is installed into the logger
and configured.
When on site, the sensors are connected to MAlog before
connecting and activating a power supply. Up to five sensors
can be connected to the logger; connectors 1 and 2 can read a
4-20mA analogue input and a pulse input, connector 3 can read
a 4-20mA analogue input.
Once the logger installation is complete, the sensors are
configured via MAlog web portal, where logging intervals
and reporting schedules are set according to individual
user requirements.
Applications
Use of an MAlog opens up a vast range of pulse and analogue
sensors for geotechnical and structural monitoring.
Typical applications include:
