Dataloggers

OTT

netDL

In addition to recording data, the loggers 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.

Features: USB-Host, USB-Device, RS-232, Satellite, Cellular, Datalogger, Industrial Communication
Product Highlights: 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
IP-Communication: Yes
Sensor interfaces: SDI-12, RS-485 (SDI-12), Modbus RTU, analogue-in (voltage and current), Impulse Input, Status Input

FEATURES

Features:

  • 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
