Microlink 840: Versatile Data Logging

DAQ Catalogue | Data Acquisition Hardware: Ethernet and Internet |  Microlink 840: Versatile Data Logging

Microlink 840: Versatile data logging over IoT

Microlink 840: Versatile data logging over IoT


Price: £295.00 (Excluding VAT at 20%)

Quantity:

The Microlink 840 lets you perform a multitude of data acquisition and control tasks, all in one small box. You can use it anywhere on an Ethernet network, over the Internet or via IoT for real-time remote data.

An eight-channel, battery-backed, data logger.

  1. Monitor Digital Sensors, including
    • Flow meters
  2. Monitor Utility Meters, including
    • Electricity meters
    • Gas meters
    • Water meters
  3. Monitor machines, for instance
    • Record percentage on/off times
    • Count items produced
  4. Monitor digital status, for instance
    • Count switch closures
  5. Count
    • Accumulating
    • Frequency
    • Period
    • Pulse width
    • Elapsed time
  6. Monitor analogue transducers, including
    • Pressure
    • Temperature
    • Force
    • Voltage
    • 4-20 mA current
    • Level
  7. Control digital outputs
  8. Raise alarms
    • Alarm on analogue level, on-off state or count
    • Set two alarms on a combination of channels
    • Switch a digital output on alarm, sounding a buzzer or turning on a light for example
    • Notify alarms to a remote PC over Ethernet or Internet
    • Insert a delay before an alarm is triggered, helping prevent false alarms

Remote Data Acquisition and Control

Log data from, and control, a mix of eight digital and analogue signals. Use as a device on the Internet-of-Things via MQTT, plug into a local Ethernet network or use the internet TCP/IP protocol. Monitor and control in real-time. Suitable for mass remote energy monitoring, level detection and status logging making it an incredibly versatile IOT tool.


Utility Meter Monitoring

Log data from gas, electricity and water meters. The Microlink 840 lets you monitor demand in real-time and identify patterns of use.

  • Continuous monitoring, logging and display
  • See consumption in real-time
  • Record total usage and usage over your chosen set intervals, for example each hour's or day's demand
  • Alarm indication on all readings - set thresholds above or below which alarms are triggered and logged
  • Each Microlink 840 can monitor 8 meters
  • Maximum count of over 16 million
  • All data is time-stamped
  • Choose custom engineering units through software, scaling readings into the required units: kilowatt-hours or cubic meters for example
  • Log the counts from the volt-free contacts of your utility meters
  • Works with any meter emitting contact closure pulses

Data can be passed to other software such as Excel spreadsheets, databases and energy management software.


Counting

The Microlink 840 offers many counting options:

  • Accumulating counter, eg for utility meter monitoring
  • Frequency counter which measures counts per second, eg for determining the rate of power consumption
  • Period counter which measures the time for a number of cycles to occur, eg for calculating the speed of a conveyor belt
  • Pulse width counter, eg for measuring the duration of an event
  • Elapsed time counter, eg for recording the length of time that a machine is on
  • 16-bit or 32-bit counting: 16-bit allows counting up to 65000; 32-bit allows counting to over 16 million.
  • Set a scale and offset factor to the count from software. For example if the pulses came from a flow meter which produced one pulse for every 50 millilitres, a scale factor of 0.05 would give a reading in litres.

Logged Data

Data can be saved as text, xml, Energy Lens, to a MySQL database and in other formats. MQTT communications allows integration into Internet-of-Things networks.

You can choose the time period over which to store data, every minute or every hour say. For each channel you can save:

  • Maximum value over the logging interval
  • Minimum value over the logging interval
  • Average value over the logging interval
  • Final value of the logging interval
  • Custom calculations on saved data
