DataBank Datalogger

The DataBank handheld datalogger is a rugged & self-contained, universal meter, datalogger, GPS & power supply that is used in combination with either a C-FLUOR or CYCLOPS 7F submersible sensor.

Sensor power is provided from the DataBank’s internal rechargeable battery. Various sensor cable lengths are available to allow sampling at different depths.

The DataBank handheld datalogger records high-frequency data which can be downloaded and graphically displayed on a PC.

GPS data is integrated into the DataBank handheld datalogger. Each line of data that is stored or exported contains time, date, and position information as well as the sample measurement. Integrated GPS data is important when conducting dye trace studies, mapping algal blooms or looking for the presence of optical brighteners as an indicator of wastewater contamination. Small and lightweight, the DataBank handheld datalogger is ideal for remote field work.

  • Stores up to 9,999 records and 16 calibrations
  • Includes auto-gain function
  • Simplifies sensor calibration
  • Station provides protection against corrosion, windblown dust and rain, water splash-down
  • Works with Cyclops-7™ Submersible Sensors
  • new Works with C-sense™ pCO2 Sensors

DataBank Electrical Specifications
Selectable Voltage: Software selectable 3 to 12 volts
Sensor Current: 150 mA at 3V to 100 mA at 12V
Parameters Warm-up Time: 0-25 seconds
Gain: 1-4
Inputs Input Selection: Switch; Differential Voltage, Differential Current or Dual Current
Range: 0-5V or 0-25 mA
Resolution: 12 bits
Sampling Rate: 1000 Hz (bursts); groups of bursts re-averaged @ 30 Hz
Outputs Two, Open Drain, up to 200 mA @ 15V max
(Used primarily for gain selection)
Storage Non-Volatile, 1280 Kb
(9,999 records, 1 record = sensor reading, date, time and location)
Current Draw Computer: < = 45 mA (at full charge). Sleeping < 20 uA
LCD Backlight: Full power ~ 30 mA. Low Power ~ 15 mA
Battery Type: NiMH rechargable, 4.8 volts, 4,000 mA/Hr.
Life: Continuous up to 70 hours (dependant on sensor/settings)
Note: When using the DataBank with the C-sense, it is recommended that the voltage be set to 6 and the warm-up time be set to 3 minutes.  Using these settings with a 5 minute sampling interval, you can expect a fully charged DataBank to collect 300 samples.
Charge Time ~3 hours (for a fully discharged battery; ambient @ 25 degrees C)
Communications USB
