Alfa Smart System is an innovative solution developed by Alfa Engineering of Modena in collaboration with SMART Consulting. This system ensures constant supervision and optimal performance of Monolithic Isolation Joints (MIJs) in cathodic protection (CP) circuits.

Alfa Smart System consists of two main components: the Smart Box and the Control and Visualization Platform. The Smart Box connects to the MIJ and the reference electrode in the field, while the Control and Visualization Platform allows for comprehensive data monitoring and management.

Typically, data transmission occurs via cellular networks, but Wi-Fi, Bluetooth, RS232, and RS485 technologies are also available. The system measures the equivalent resistance of the circuit and the CP voltages. We offer two models: one with a bypass function for the joint and one without. Real-time alarm transmission ensures effective and timely supervision.

How Alfa Smart System Works

The Smart Box installs near the MIJ and connects to the reference electrode. Configuration happens through the control platform, where you set operational parameters and alarm thresholds. Once set up, the system continuously monitors the equivalent resistance of the circuit and CP voltages. Data from the Smart Box transmits in real-time to the control platform using the chosen technology.

Alfa Smart System How Work

The control platform processes the data, providing clear and intuitive visualizations of system conditions. Operators access both historical and real-time data and can set customized alerts for anomalies. If an anomaly or threshold breach occurs, the system immediately sends alarms via SMS, email, or push notifications.

For models with the bypass function, the system can automatically activate the bypass in critical situations to ensure service continuity. Operators can also manually manage the bypass through the control platform.

Benefits of Alfa Smart System

Alfa Smart System enhances operational efficiency through constant, real-time monitoring. Immediate alarm transmission reduces intervention times. The robust system performs reliably even in challenging environments. It lowers maintenance costs by reducing on-site visits and enables preventative maintenance through early fault detection.


The system improves operational safety by identifying problems promptly, reducing accident risks. Its continuous monitoring capabilities ensure the safety of MIJs. The system’s flexibility and scalability allow integration of new transmission technologies and adaptation to various needs. Environmental sustainability is another advantage, reducing CO2 emissions and optimizing resource use.

Real-World Applications and Case Studies

Case Study 1: Smart Box Installation on a Railway Backbone

A Smart Box installed along a national railway backbone demonstrated its ability to withstand electromagnetic interference from passing trains. Initially, this interference caused unintentional relay coil activation, shorting the MIJ. The issue was resolved by replacing the relay type and developing a relay-less model with improved control logic.

Case Study 2: Roadside Installation with Inductive Interference

A Smart Box installed roadside with 50 Hz inductive interference successfully transmitted alarms during an unplanned maintenance event. This event underscored the system’s reliability in real-world conditions, as it promptly alerted the control center to the anomaly.

Collaboration with Automa Srl

Alfa Engineering has initiated a collaboration with Automa Srl. This partnership integrates the Alfa Smart System circuit into Automa’s supervision system. The collaboration aims to create synergy between technologies, improving the efficiency and management of Automasupervision systems. It also seeks to expand the functionalities and applications of the Alfa Smart System.
