Inputs for serial sensors

The M-Log COM-2 port can be connected to hot wire anemometers or to sensors with Modbus-RTU protocol output.

Sensors acquisition rate

Acquisition rate is programmable for each input (from 1 sec to 12 hours). M-Log manages 4 channels from analog inputs and 8 derived quantities in 1 sec. To limit energy consumption from sensors requiring power supply, it is possible to set an advanced power supply from the acquisition event (warm-up), that is interrupted immediately after the acquisition itself.

Data elaboration

  • The raw measured values can be stored directly as instantaneous values, or be stored as statistical processing (n. 1 base, form 1 sec to 12 hours);
  • Average, minimum, maximum, standard deviation;
  • Wind elaborations;
  • Totals.

Derived and calculated quantities

Internal library of derived environmental quantities. These calculations use acquired quantities, constant values and other calculated quantities. The library also includes mathematical functions. M-Log manages up to 50 channels between acquired, derived and calculated quantities.

Data memory

Internal memory (8MB) allows to store data typically for several weeks. The registration structure is circular. In the model (ELO009) with MiniDIN inputs the data is stored in “surveys” with progressive numbering and data/time start/end.
