Introduction
The Multilogger has been designed for measuring and recording physical
and electric quantities with an adjustable logging interval from 1 second to
24 hours. The device is equipped with 4 inputs (connectors) for external
probes or signals. Moreover, some versions also include an internal
atmospheric pressure and/or CO
2
concentration sensor. The production
line consists of several models with various combinations of the input
ranges of the measured quantities. The Multilogger can be used either as
stationary or portable device.
The device allows for:
- Measuring and processing input quantities; the maximum number of
the measured and calculated quantities is 16. Some models can also
acquire data from binary inputs (up to 2 inputs). Models for measuring
barometric pressure allow sea level recalculation.
- Finding and storing minimal and maximal values for each measured
quantity (since their last manual reset).
- Acquiring autonomous time record of measured values, independent
of the mains supply. Recorded values can be stored as separate
samples in the recording time or as average/ minimal/maximal values
during the logging interval. Recording may be continuous, or only
during an alarm optionally.
- Creating alarm states and perform actions (audio and optical
signalization, alarm output signal, report messages via telephone
dialer and/or various Ethernet interface protocols, etc.).
- On-line monitoring of the measured values and states. Accessing
these values via the web.
- Collecting and processing data in the central database.
- Powering by batteries (NiMH accumulators or alkaline batteries).
- Powering by external power supply, which can be also used for
charging NiMH accumulators. External power supply is required for
full operation of the Ethernet interface. Some limited functions of this
interface may be available during battery operation.
