Enhance performance
Exertherm ensures robust and secure communication of temperature data without the risk of signal interference or cybersecurity threats.
Exertherm’s sensors provide a direct and continuous view of critical joints or terminations, measuring Delta T (temperature rise over ambient) from within the switchgear enclosure.
Continuous thermal monitoring allows for the early detection of potential issues, reduce unexpected failures and enhancing the overall reliability and safety of electrical systems.
Sensor placement – contactless sensors
One of the standout features of Exertherm’s technology is the use of contactless infrared sensors. Unlike many other sensors in the market that attach directly to conductors, Exertherm’s sensors do not make contact with any conductor. This design choice is crucial for several reasons:
- Reduced risk of system weakness
- Avoidance of insecure attachments
Reduced risk of system weakness
Directly attached sensors can introduce weaknesses into the power distribution system. They often require different torque settings for bolted joint connections, which can compromise the system’s integrity. Exertherm’s contactless approach eliminates this risk, ensuring a more robust and reliable system.
Avoidance of insecure attachments
Sensors attached using Velcro tape or cable ties can lead to insecure connections and longevity issues, becoming a maintenance headache over time. Exertherm’s sensors, fully commissioned at the factory before installation, ensure a secure and reliable setup, minimizing on-site complications and maintenance needs.
Sensor communication – wired sensors
Exertherm’s sensors are hard-wired, a significant advantage over the wireless alternatives commonly found in the market. Here’s why this matters:
Elimination of antenna requirements
Wireless sensors often require multiple antennas to align RF fields correctly, with transmission distances typically limited to around 30cm under ideal conditions. Exertherm’s hard-wired sensors eliminate the need for antennas, ensuring consistent and reliable communication.
Enhanced
security
Wireless sensors pose a cybersecurity risk due to potential hacking vulnerabilities. By opting for hard-wired sensors, Exertherm ensures robust and secure communication without the risk of signal interference or cybersecurity threats.
Reliable data
transmission
Wireless sensors can suffer from compromised signals due to electromagnetic fields (EMF) and electromagnetic compatibility (EMC) issues. Exertherm’s hard-wired approach guarantees reliable data transmission, free from such interferences.
Sensor powering – non powered sensors
Another significant advantage of Exertherm’s sensors is their ability to operate without an external power source. This feature offers several benefits:
- No need for amplifiers
- Maintenance-free operation
No need for amplifiers
Unlike other sensors that require amplifiers, which can introduce drift and necessitate periodic calibration and costly shutdowns, Exertherm’s sensors derive power directly from the target. This design eliminates the need for external power sources, reducing maintenance requirements and ensuring continuous operation without interruptions.
Maintenance-free operation
Exertherm’s sensors do not require batteries, eliminating the need for periodic maintenance or battery replacement. This feature maximizes uptime and ensures that the sensors can operate continuously without any interruptions.

Accurate data via Delta T measurement
Exertherm’s sensors provide a direct and continuous view of critical joints or terminations, measuring Delta T (temperature rise over ambient) from within the switchgear enclosure. This approach offers several advantages:
Elimination of temperature correlation
Most other sensors only measure absolute temperature at the busbar joint or require an additional ambient sensor, necessitating temperature correlation and Delta T calculations in the front-end system. Exertherm’s approach eliminates these variances, allowing for accurate alarm levels based on NETA guidelines.
Consistent and reliable data
By measuring Delta T directly, Exertherm’s sensors ensure consistent and reliable data across different panels and sites. This consistency is crucial for accurate monitoring and maintenance of electrical systems.
Considering load in monitoring
Load plays a crucial role in detecting compromised joints or terminations accurately. Exertherm’s LoadMap™ software, used alongside continuous thermal monitoring sensors, calculates alarm thresholds suitable for the maximum load on the monitored circuit. Here’s how this works:
Accurate detection at low loads
By utilizing temperature and load data, Exertherm’s system can detect compromised joints even at low loads. This capability is essential for early detection and prevention of potential issues.
Dynamic load data integration
Users can manually enter the maximum anticipated load or obtain dynamic load data via a metering device. This integration allows Exertherm’s sensors to provide load-based warning alarms, offering an enhanced level of 24x7 facility protection.
Enhanced facility protection
By considering load in its monitoring approach, Exertherm provides a comprehensive solution that enhances the safety and efficiency of electrical systems. This feature ensures that the system can operate at optimal levels without the risk of overloading or compromising the integrity of the connections.
