Data Logger Vlog Rain Vlog-Level
The VLOG-RAIN smart data logger provides an extensive array of features that allow it to be used across a wide variety of applications. The VLOG-RAIN is a robust, stand alone, low power data logger featuring USB memory stick support, 24-bit resolution, extensive communications capabilities and built-in display & keypad. The SensorMart’ s VLOG-RAIN Dual Channel concept allows T ipping Bucket rain gauge to be Connected & measure rain values in 0.2mm resolution .
With support for 1 SDI-12 sensor networks, RS485 for large display systems, GSM Modem interface , 12V regulated output to power sensors, the VLOG-RAIN is a totally self-contained solution.User can connect an array of rain sensors through sensor the versatile analog and digital channels, high-speed counter inputs and programmable serial 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, GPS and other intelligent devices expand the VLOG-RAIN 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.
