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

MT-718 PS is a compact, battery-powered telemetry module designed for monitoring, logging and data transmission in water supply, industrial and environmental applications. Thanks to 2G/4G packet transmission (Cat 1 or NB-IoT/LTE Cat M1 – depending on the version), the device ensures reliable connectivity even in locations without power supply and access to infrastructure.

The integrated data logger with a capacity of up to 65,000 records allows for precise collection of measurements with a resolution of up to 1 second. Low energy consumption, advanced sleep modes and the possibility of powering from replaceable batteries (alkaline or lithium) ensure years of maintenance-free operation.

The device is equipped with 5 binary/counter inputs, 2 analogue inputs 0–5 V DC (with 4–20 mA conversion option), a built-in pressure transducer, temperature and humidity sensors, and an RS-485 interface with Modbus RTU support. An optional OLED display and the option of remote configuration and firmware updates via OTA increase functionality and user-friendliness.

The housing with protection class IP68 allows installation in areas exposed to moisture and periodic flooding – up to 2 metres of submersion for 24 hours.

• Data transmission via 2G/4G Cat 1 or NB-IoT/LTE Cat M1 – depending on the modem version.
• 5 binary/counter inputs – for use with sensors and pulse flow meters.
• 2 analogue inputs 0–5 V DC with 4–20 mA conversion option – for level, pressure and temperature measurement.
• Integrated pressure sensor 0–10 bar – quick connection via hose connector.
• 2 digital outputs – for controlling external devices.
• Data logger (up to 65,000 records, 1 s resolution).
• Battery power supply with status monitoring – long-term, independent operation.
• Built-in temperature and humidity sensors.
• Housing opening sensor – tamper protection function.
• RS-485 with Modbus RTU protocol – integration with SCADA systems.
• Optional OLED display – local data preview.
• Remote configuration and firmware update OTA.
• IP68 housing – resistant to harsh environmental conditions.

• Monitoring of water supply networks – recording of flow, pressure and water level; can be installed in measuring chambers without access to power.
• Automation and IoT systems – integration with devices via RS-485, Modbus RTU support, local control and logic thanks to uProg.
• Environmental monitoring – measurement of environmental conditions (humidity, temperature), cooperation with probes and transducers.
• Remote diagnostics and control – access to data and configuration via mobile networks, event- and schedule-based communication.
• Security and alarm systems – detection of enclosure opening, lack of flow, threshold exceedances – event and alarm reporting.
