EOL Zenith

EOL Zenith data logger without lid


The manufacture of the EOL Zenith has been discontinued. We will continue to accept orders for the EOL Zenith data logger until 30/06/2020 and provide continuous technical support for the EOL Zenith until 30/06/2025. Replacement logger: Orbit 360. For more information about this announcement see below.

With a significant number of Orbit 360 data loggers now in the market, and with most of our customers already transitioned from the EOL Zenith to the Orbit 360, it is now time for the rest of our customers to benefit from the well-integrated improvements in the Orbit 360.

We have therefore decided to discontinue the manufacture of the EOL Zenith data logger. We will continue to accept orders for the EOL Zenith data logger until 30/06/2020 and provide continuous technical support for the EOL Zenith until 30/06/2025.

The Orbit 360 models are designed so our customers can easily make the transition from the EOL Zenith to the Orbit 360 product range whilst immediately benefitting from all the new features in the Orbit 360 product range as well as our new fleet management software, Atlas.

The EOL Zenith data logger collects data in compliance with IEC61400-12 for high-quality wind and solar resource assessment when maximum performance, reliability, and ease of use is a must. It is the perfect combination of data logger technology coupled with cutting-edge remote data collection and management software.

The EOL Zenith is designed for optimal performance in any climate – from the bitter colds of northern Norway to the desert heat of Egypt. Read our related case studies (Case Study 7 or Case Study 2).

This exceptionally versatile performance is thanks to the carefully designed electronics, robust and reliable components, and low power consumption of the data logger – a feature that remains unique to the EOL Zenith and of crucial importance when operating in remote areas. Specific design features include:

  • 1Hz sampling rate (complying with IEC61400-12)
  • Advanced sensor error diagnosis
  • Live real-time data (bi-directional communication)
  • GPS time stamp and synchronization
  • Automatic file download
  • Multiple data delivery and forward options
  • 10 min. averaging interval (user selectable)
  • Data encryption and 2 level password protection
  • No interface cards required
  • No programming required
  • SCADA/Modbus capability (option)
  • Ultrasonic capability (option)
  • Met mast management tool (EOL Manager) that helps keep track of all your sites

The EOL Zenith data logger offers a wide range of possibilities and is the core component in wind resource measure­ment campaigns. By default, the data logger comes equipped with GSM/GPRS communication capabilities. Due to its very low energy consumption, a 10W solar panel is sufficient for standard operation (dependent upon hours of sunlight, latitude, etc.)

The software and remote monitoring system for the EOL Zenith data logger ensures reliable and easy access to wind data and logger status, and forms an integral part of the data acquisition system.

Download data, collect real-time values, refine logger settings remotely and keep all your wind data organized.

  • Dashboard with site-by-site status, with direct access to site coordinates via Google Earth
  • Automatic data download from unlimited number of sites
  • Advanced sensor error diagnosis
  • User selectable output format incl. EPE (Brazil) and MGM (Turkey)
  • Upload new logger settings OTA
  • Live real-time data (bi-directional communication)
  • Multiple data delivery and forward options
  • User configurable password protection

EOL Manager includes advanced graphics for more accurate wind data trouble-shooting as well as enhanced control of multiple wind assessment sites with automatic and real time connectivity.

In short EOL Manager offers ‘at a glance’ status of all your data loggers in the field with easy identification of sensor faults. It also allows for configuration of the data loggers, download frequency etc.
