Databank El Tipi Veri Kaydedici

The DataBank™ is a rugged and self-contained universal meter, datalogger and power supply. Specifically designed for use with the Cyclops-7 and C-sense product lines, sensor calibration and operation are simple. The DataBank records high-frequency data which may be downloaded and graphically displayed on a pc. Sensor power is provided directly from the DataBank’s internal rechargeable batteries. Alternatively, an external +12 VDC power can be used. Various sensor cable lengths are available to allow sampling at multiple depths.

DataBank Datalogger Specifications

DataBank Electrical Specifications
Selectable Sensor Parameters Voltage: Software selectable 3 to 12 volts
Current: 150 mA at 3V to 100 mA at 12V 
Warm-up Time: 0-25 seconds
Gain: 1-4

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
