Data Logger L-Log
The Model- Llog smart data logger provides an extensive array of features that allow it to be used across a wide variety of applications. The Model- Llog is a robust, stand alone, low power data logger featuring USB memory stick support,18-bit resolution, extensive communications capabilities and built-in display & keypad.
The SensorMart’ s Model-Llog Dual Channel concept allows up to 2 common referenced analog inputs to be used to measure flow values from flow meters/Level Sensors/Rain Sensors.
With support for sensors RS485 for large display systems, GSM Modem interface , 12V regulated output to power sensors, the Model-Llog is a totally self-contained solution. User can connect sensors through the versatile analog and digital channels, high-speed counter inputs and programmable serial sensor channels.
Temperature, voltage, current, 4-20mA loops, resistance, calculated measurements can all be scaled, logged and returned in engineering units or within statistical reporting. Set up sampling, logging, and control tasks to suit user requirements while interfaces for smart sensors and other intelligent devices expand the L-log flexibility . With the standard unit able to store up to 1 million data points you can log as much or as little as you need. Overwrite once allocated memory is full, copy to USB memory or transfer via HTTP , the choice is yours.
