After a four-month-trial period, flatGEO has finished a datalogger system for consolidation tests on oedometer systems made by Nanjing Soil Instrument company in China.
The flatGEO-datalogger system uses displacement transducers produced by Novotechnik (Germany) with following technical specifications:
Max stroke | 10.0 mm |
Repeatability | 0.002 mm |
Operating temperature | -30°C ~ +100°C |
Protection class | IP40 |
This datalogger system has some advantages to other datalogger systems:
1) Data could be saved to a MySQL database on a desktop computer or to a SD memory card.
2) The reading intervals could be customized conveniently.
3) The positive direction of transducers could be changed easily.
4) Data can be transferred to a PC via RS-232 or RS-485.
