Which of the following is a smart sensor benefit?

Self-diagnostics is a significant benefit of smart sensors because it allows these devices to monitor their own functionality and performance continuously. This capability can ensure that the sensors are operating correctly and can alert operators or systems to potential issues before they lead to failures or significant downtime. Self-diagnostic features contribute to improved reliability and maintenance, as they facilitate proactive decision-making regarding repairs or replacements, thereby enhancing overall operational efficiency.

In contrast, other options such as low cost, limited range, and complex installation do not represent the advantages typically associated with smart sensors. While cost can be a factor, smart sensors often come with a higher price tag due to their advanced features. Limited range is a disadvantage, as it restricts the sensor’s effectiveness in monitoring processes across larger areas. Finally, complex installation can hinder the deployment of smart sensors, making them less accessible in certain contexts.
