MT-723 PT logger and transmission module has highest grade of protection in harsh environment. As other modules of MT family it is known for innovative design, advanced technologies and for ease of configuration and integration in data collection and processing systems. Spontaneous data transmission on event occurrence allow minimizing transmission costs and energy consumption thus prolonging battery life time. However it is possible to set up device to stay online permanently or for desired time thus allowing to poll both current, logged or both types of data asynchronously from module. Simple, robust design enclosed in polycarbonate housing with IP-68 ingress protection class allows installation in harsh environment where there is no supply of electricity (like for instance water supply systems measuring chambers).

The module may be powered from alkaline batteries, lithium batteries, lead batteries, solar panels or from power lines.

The level of power supply is constantly monitored and reported along with measurement data. Internal lithium battery secures pulse counting on inputs I1–I6 secures RTC clock function and alarm transmission in case of main supply failure.

MT-723 PT is equipped with: 6 binary/counter inputs (adapted to work with potential free contacts for water consumption meter), 2 analogue inputs allowing measuring various parameters like pressure, temperature, level, humidity. The module has a pressure gauge with quick coupling allowing comfortable connection with pressure hose. Extremely low power consumption is achieved by deactivating GPRS/GSM modem when not transmitting and using latched power supply output for external analogue sensors or for controlling power supply to external equipment only for measuring time. Measurement data may be registered with precise time stamp in non volatile Flash memory either by schedule or on event.

The module can beyond measuring issue alerts in case of mechanical shock, submersion, unauthorized chamber opening, lack of flow, too high flow, high pressure, high level, temperature, humidity etc.

The configuration environment and communication application with open OPC/ODBC/CSV interfaces and an application for remote management via GPRS network comes free of charge with the purchase of the module. The user may unrestricted use new firmware versions thanks to capability of remote upgrading.
