- Model Meteo-40 - Meteo Data Logger



The Meteo-40 data logger is the heart of your measurement system. The data logger ensures accurate measurements to the high standards required by professional consultants, operators and climate research institutes. The Meteo-40 series is designed for wind and solar resource assessment as well as for monitoring of wind farms and solar power plants. Additionally, Meteo-40 can be implemented in traffic and agricultural meteorology. Meteo-40 data loggers are suitable for all climates and remote regions thanks to well-designed technology and low power consumption. Meteo-40 can easily be integrated in SCADA systems to provide reliable comparative meteorological data. Considering the measurement data recorded by Meteo-40, for example predictions about the annual production can be verified. With its configurable Modbus Register Map, Meteo-40 is designed for operation in most existing SCADA system.

Meteo-40 offers up to 2 GB memory recording of complete 1-second original measurement data (for approximately 1 year with typical number of sensors), high resolution (16 bit and 8 Hz), analog channels with a choice of various input ranges to choose from, a digital channel for smart sensors, 3 USB-slots for PC, modem and adapter connections (GSM / GPRS / CDMA / WiFi / Ethernet / memory stick / RS-485). Meteo-40 is available in three configurations Meteo-40L (large) with 35 channels, Meteo-40M (medium) with 22 channels and Meteo-40S (small) with 11 channels.

Ammonit data loggers are the core of each wind and solar measuring station. Our self-contained measuring systems are reliably powered by a 50W solar panel. Storage in a CE-certified steel cabinet protects the data logger against weather and condensation damage as well as theft and vandalism. Several optional components may be included, such as a remote communication module, a barometric pressure sensor, a battery and overvoltage protection. The data transfer between PC and logger can be performed via HTTPS, FTP, SCP connection, email, satellite or direct interface.
