Application
* Automatic measurement of hard to access site as like harbor, bridge, dam and subway
* Much electrical noise site in city as like subway
* Other soft ground, tunnel, sheathing site
Characteristic
Automatic static data logger SJ-1000 is structured by measuring terminal, communication module and wiring panel.
Measuring terminal is 16cannels and can be expanded to 64channels by connection of 3 muxs. RS485 module can
measure 86 sensors by communication only. Power is DV 12V and Min. 9.8V can operate data logger. Built in memory
is 32MB and various digital or analog sensor can be measured.
Feature
* 16 Channels data logger : 16 Sensors can be connected to data logger.
* Avail to connection with 3 Muxs : Each Mux has 16 channels and Max. 3 Mux can be connected by series.
* Small quiescent current : 20mA
* Small sleep current : 40uA (Clock can be operated for 9 months by Ni-Cd battery without main power.
* Big memory (32MB)
* 4 kinds output sensors can be connected.: Vibration wire type, voltage, current, digital(485)
* Accurate measurement
* Strong design
* Not only logger manager also data acquisition function
* Test data can be changed easily to excel file.
* Test data can be analyzed because test data are divided into logger (Modem) and arrange data in order of sensors.
* Auto time setup
* Auto start : If operator not start schedule, when data logger start data acquisition, data logger start schedule.
* Data logger can test by sensors and save data separately without PC.
