MT-718 – battery-operated, energy-efficient telemetry logger with IP68

MT-718 is a new battery powered telemetry module for measuring and data logging. Like other modules of MT family the module is a cutting edge design characterized by advanced innovative solutions, easy to configure and integrate with data collecting and processing systems. The spontaneous on event-based or scheduled data transmission helps to minimize transmission costs and energy consumption extending battery life time. Simple compact design in plastic enclosure with IP 68 protection makes the module ideal for harsh environment with no acess to amins power supply (eg. water supply control wells and measurement chambers). Module can be powered with user replaceable battery or external battery pack set. Battery voltage is continuously monitored and reported along with measurement data. MT-718 is equipped with 5 binary/counter inputs (adopted to work with potential free contacts) and 3 analogue inputs allowing measuring of parameters like pressure, temperature, level etc. Additionally, there is a built-in 4-20 mA to 0-5 VDC converter for 2 analog signals. RS-485 interface supporting Modbus RTU and NMEA allows connecting external devices (including GPS receiver).

Keyed voltage source powering analog inputs and voltage outputs for external sensors as well as advanced work modes of internal modem reduce energy consumption to absolute minimum. Measurement data may be logged with a precise time stamp in nonvolatile Flash memory according to configured schedule or when defined event occurs. Measurement data may be also presented on optional OLED display.

Besides measurements the module can report multiple alerts: tampering with enclosure, unauthorized opening of the chamber, long period of missing flow, crossing the predefined level or reaching the temperature threshold etc. MT-718 module’s resources and functionality may be optimized for particular applications due to many available options (lithium or alkaline battery packs, M12 connectors, built-in OLED display, 2G/4G Cat. 1 or 2G/NB-IoT/LTE Cat. M1 modem version).
