    MT-723, Energy efficient GPRS/SMS Datalogger, IP68

    MT-723 module is a data logging and transmitting device with the highest degree of protection against harsh external environment. Like other modules from MT family, MT-723 module is a cutting edge design characterized by technological advancement, innovative solutions, ease of configuration and integration with data gathering and processing systems. The module has the possibility of initiating data transmission (event-driven or scheduled) which helps to minimize the transmission costs and energy consumption, therefore increasing battery life. However it is possible to set up the device to stay online permanently or for a desired time thus allowing to poll both current, logged or both types of data asynchronously from the module.

    Robust, compact design enclosed in a polycarbonate housing with IP68 protection module allows installation and usage of module in places with harsh environment and without power supply (such as water supply network measuring chambers). The module can be powered from alkaline or lithium battery packs, batteries, solar panels as well as from stationary sources of power. Voltage level of power source is constantly monitored and transmitted together with measurement data. In the case of disconnection of an external power supply internal lithium battery provides power essential for counting pulses on inputs I1 ? I6, sustains the RTC clock and triggers power loss alarm.

    The MT-723 module is equipped with 6 binary/counter inputs (supporting potential free contacts used e.g. as pulse outputs of water meters) and three analogue inputs for measuring parameters such as pressure, temperature, water level, etc. Keyed voltage source for powering analog sensors which provides power only for a short time needed for measurement and outputs that can be used for controlling external power source powering analog sensors are solutions which, in conjunction with the deactivation of GSM/GPRS modem when there is no data transmission, ensure an extremely low power consumption. Measurement data is stamped with precise time and can be recorded in nonvolatile Flash memory. In addition to measuring functions the module can also report states of emergency such as mechanical shock, flooding, unauthorized opening of the chamber, lack of flow, exceeding specified level of flow, pressure, water level, temperature, humidity, etc. Resources and functionality of the MT-723 module can be optimized for specific applications thanks to the many available options (module flooding sensor, pressure transmitter, GPS receiver). The module is supplied with user friendly configuration environment and communication driver providing OPC, ODBC and CSV interfaces for data reception and the software for remote management via GPRS. User can manage modules from remote via GPRS. Remote management includes firmware updates.
