Multichannel Data Loggers


Nine Channel Environmental Data Logger for Recording a Variety of Sensor Signals

Features

  • Four sample modes: 10 times per second, timed, logarithmic, and exception
  • Both USB and Serial communication ports
  • Monitor up to 9 sensors at a time in addition to battery voltage
  • Battery powered for remote locations
  • User friendly Windows and PDA software included
  • Accepts any 4-20mA input
  • Optional rugged, lockable, weather resistant enclosure


The Global multichannel datalogger, GL500, is the latest addition to our line of rugged remote recording instrumentation.  It features 7 analog channels and 2 digital channels for data recording.  The GL500 can record over 40,000 readings and has four unique recording options, fast (10 samples per second), programmable interval (1 second to multiple years), logarithmic, and exception.  The datalogger also has a sample on demand input that triggers a recording of special events, such as when a water sampler was triggered, when a door was opened, etc.  Daily start and stop alarm times can be programmed to limit recording intervals during a day.  The GL500 includes Windows and PDA software, allowing easy upload of data to a laptop, desktop, or PDA for transfer to a spreadsheet program.  NOTE: The Palm operating system is NOT supported. 


Bluetooth Capability

The GL500-7-2-BT Data Logger is a version of Global Water's popular GL500 logger plus a built in Bluetooth 2.0 serial interface for accessing data and settings without the use of a custom connection cable.  Using a PDA, laptop or desktop computer with Bluetooth capability; the data logger's data and settings can be viewed, stored and programmed using the Global Logger II desktop and PDA software packages, as well as the Flow Monitor software.  All of the features in these data logger software packages are available using the Bluetooth interface.

Because the Bluetooth module draws power when turned on, the data logger features a power switch so you can turning it off when not in use.  A red LED indicates when the data logger's Bluetooth module is on and a blue LED shows the status of the Bluetooth connection.


Data Logger Inputs

The Global data logger is setup to accept any 4-20 mA sensor.  The GL500 provides switched power to the sensors based on the sample interval and sensor warm up time settings.  Twisted pair 2-wire and 3-wire sensors can be quickly connected to the datalogger's terminal strip and calibrated via the Global datalogger software.  Your sensors can be accessed through dial-out to a remote modem attached to the GL500's serial communication port.  The datalogger software has online help files that are easily accessed using drop down menus and links to quickly find the answers to your questions.

The data recorder has an optional rugged, lockable and weather-resistant enclosure that can easily be hidden, bolted to a post, or secured inside an additional container for added protection from the elements, animals or vandals.  A 12VDC rechargeable battery and battery charger come with the data logger enclosure option.
