OTT netDL Datalogger
IP data logger OTT netDL
The versatile OTT netDL 500 and 1000 dataloggers were developed specifically for use in hydrology and meteorology stations. In addition to recording data, the dataloggers are extremely low power and offer flexible data transfer options via the internet and mobile networks, providing a logging and telemetry solution for every project.
- Ethernet, USB-Host, USB-Device, RS-232, Satellite, Radio, Data Logger
- High data availability due to large memory and various communication possibilities, redundant communication, communication via TCP/IP Integrated Web Server, Ultra low power design Industrial design for harsh environment, industrial communication
- Yes
- SDI-12, RS-485 (SDI-12), Modbus RTU, analogue-in (voltage and current), Impulse Input, Status Input
- An integrated web server allows access to the datalogger using standard browsers, no additional software is required
- Standardized ports and a variety of supported transmission protocols (HTTP, SMTP, FTP) and data formats (including XML) allow simple integration into existing and future systems, thus securing a long-term investment
- Redundant communication paths ensure complete data availability
- Extremely low power consumption allows prolonged use at remote locations
- Every datalogger can be individually equipped for a project, simply needing to incorporate it with the input/output modules for the application
- Parallel processing of the data from all connected sensors makes short sampling intervals possible
- Instantaneous values and other information can be read out quickly and conveniently at the measurement site with the unit's display
Data logging and transmission in hydrological and meteorological applications via:
- GPS/GPRS modem: communicate via the cell phone network and/or mobile internet
- Ethernet: fast and direct internet method (netDL 1000 only)
- RS-232: for connection to external transmission devices like the OTT HDR 1200 GOES Satellite Transmitter
- USB: simple, direct access to the datalogger on-site via laptop or USB stick
