Features of Digi Connect® Sensor XRT-M

The Digi Connect® Sensor XRT-M enables remote telemetry with cellular connectivity and integrated protocols. It supports sensor interfacing, cloud data transmission, and configurable operation for industrial monitoring applications. Let’s go through its features in detail:

Cellular Connectivity and Communication Protocols

The device supports dual-mode LTE-M and NB-IoT connectivity for low-power wide-area communication. It integrates MQTT for lightweight data transmission and Modbus for compatibility with industrial sensors, enabling direct communication with cloud platforms.

Sensor Integration and Data Acquisition

The gateway can connect to and supply power to multiple industry-standard sensors. Configurable read and reporting intervals allow control over data acquisition frequency, supporting various telemetry requirements. This enables efficient monitoring of remote assets with minimal manual intervention.

Cloud Integration and Remote Management

 Sensor data and device health information are transmitted to Digi Axess, where they are stored and processed. The platform provides tools for configuration, analytics, and alert generation. Mobile management through iOS and Android applications supports remote monitoring and system control. 

Power System and Operational Efficiency 

The system uses dual 12Ah batteries to support extended operation in remote deployments. Low-power cellular communication and configurable reporting intervals contribute to efficient energy usage, enabling long-term field operation without frequent maintenance. 

Industrial Design and Environmental Operation 

The device operates within a temperature range of -35°C to 70°C and is housed in a NEMA enclosure with C1D2 certification. This supports deployment in industrial environments, including hazardous locations, where exposure to harsh conditions is expected. 

Applications

The Digi Connect Sensor XRT-M is used in water and wastewater management for monitoring flow levels, pressure, and system performance across distributed infrastructure. In oil and gas operations, it supports remote monitoring of pipelines, tanks, and gas distribution systems. Within industrial automation, the gateway enables data collection from field sensors for process monitoring and control. It is also applied in environmental monitoring to track parameters such as air quality, water conditions, and regulatory compliance metrics. The device supports remote telemetry in locations where wired connectivity is not feasible, enabling reliable data transmission and system visibility across large or isolated sites.
