SymphoniePRO Datalogger

Advanced Datalogging System

SymphoniePRO is an industrial-grade, low-power data logger that is specifically designed for conducting resource assessments for the renewable energy industry. With options for either 26-channel or 16-channel wiring panels, the logger’s measurement capacity can be optimized as needed. Each channel’s statistical values are calculated from continuous 1-second data samples and averaged over a user-selectable interval (10-minute default). Collected data are stored efficiently as binary *.RLD files on internal Flash memory with a redundant copy on an external SD card, if installed.

Data are transferred and the system is powered via our line of Symphonie iPackGPS communication and power modules, which only require a firmware upgrade for compatibility with the new data logger. In addition to SMTP email data delivery, SymphoniePRO allows remote, real-time connection capability over our MetLink protocol for tasks like automated or manual data download, firmware upgrades, live data viewing, or configuration changes.

The SymphoniePRO Desktop Application is a modern and intuitive PC software package used to process raw data files as well as configure and communicate with the SymphoniePRO logger and iPack. SymphoniePRO Desktop Application keeps track of site data and produces versatile tab-delimited text files (ASCII) compatible with industry-leading software. Additionally, the software allows the user to view “live” data, apply firmware updates to loggers and iPacks, and preview data files in time series format.


SymphoniePRO Desktop Application is engineered to work seamlessly with SymphoniePRO data loggers to configure equipment, process data, and manage your fleet of measurement stations.


State-of-the-art technology delivers accurate measurements and provides the freedom to perform advanced studies with your preferred configuration.

  • 26+ channels provide ample capacity for typical resource assessment campaigns or special projects alike—including 12 counter, 14 analog, and two RS-485 ports.
  • User-selectable averaging interval (10-minute default) allows you to record data at the optimal rate for your application.
  • IEC-compliant 1 Hz sample rate with optional storage of 1 Hz sample data by channel—facilitates advanced studies like wind turbine site suitability or ramp rate studies for the integration of utility-scale projects on small grids.
  • Design is compatible with a wide array of industry-standard and specialized devices so your measurement campaign’s design is not limited by your data logger.
    • Counter channels and built-in analog channels include native compatibility with industry-standard sensors – no peripherals required;
    • SymphoniePRO Signal Conditioning Modules (P-SCMs) customize analog input circuitry to optimize measurements for third-party analog devices;
    • Two RS-485 ports each support full or half duplex communication with smart sensors like ultrasonic wind sensors.
  • Our line of Symphonie iPack options allow your SymphoniePRO Data Logger to cover the full range of renewable energy applications from any location, worldwide.
    • Cellular: 2G (GPRS) or 3G GSM, CDMA
    • Satellite: Inmarsat BGAN M2M
    • SCADA: Modbus TCP via iPackACCESS
  • Accurate, high-resolution analog measurements via 16-bit ADC for all meteorological sensors virtually eliminate measurement quantization error.
  • Differential inputs on P-SCM channels improve the measurement of small signal sensors, isolating signal from ground noise.
  • Three-second gust is recorded on each wind speed channel in addition to min and max 1-second samples.
  • Configurable dead-band compensation allows for more accurate wind direction data from a wider array of sensors.
  • Extensive meta data are collected, including logger diagnostics, communications information, and events—facilitating intelligent site and fleet management.
  • Collected data are stored reliably and securely with:
    • Redundant storage on internal Flash and industrial-rated SD card;
    • Logger access PIN, preventing unauthorized access (optional);
    • 128-bit file encryption (optional);
    • SymphoniePRO Wiring Panels, providing channel-by-channel surge protection, tested to IEC-61400-4-5;
    • Accurate and reliable time-keeping with Lithium battery-backed real-time clock. Integrated GPS automatically provides current location information and GPS time synchronization in addition to SNTP internet time server time sync.
