DataBank Logger

Data can be stored and downloaded to a PC. Sensor calibration is simplified through continuous sensor readings with results graphically displayed. Sensor power is provided directly from the DataBank which is powered by internal rechargeable batteries, an external 9-30VDC power source such as a 12V marine battery, or AC power. Available in two configurations: a handheld package for easy transport during mobile field studies and an enclosure for long-term stationary field deployment.

  • 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
