Metis Engineering, a leader in advanced Controller Area Network (CAN)-based sensor technology, today introduced its new 8-Channel Isolated Thermocouple to CAN module. This powerful new device is designed specifically to meet the exacting temperature monitoring demands of industrial, automotive, and research applications globally.
The launch marks a significant advance in thermocouple technology. Each channel features galvanic isolation up to 1000VDC, eliminating common ground loop issues and electrical interference. This isolation ensures measurement reliability, especially in critical high-voltage environments.
Unparalleled Precision and Isolation for High-Voltage Systems
The new module delivers reliable performance even in the most challenging electrical environments. It offers precision accuracy of ±0.5∘C from 0∘C to 85∘C and ±1∘C across the full operating range from −40∘C to 125∘C.
The core advantage is its superior isolation capability.
- Isolation: The high isolation level exceeding 1000VDC allows safe and accurate temperature sensing inside high-voltage systems. This includes applications such as electric vehicle (EV) battery packs, high-power electronics, and industrial inverters.
- Measurement Range: The device measures temperatures across an exceptional range, spanning from −200∘C to +1,800∘C. This wide capability is perfect for applications from cryogenic research to high-temperature industrial processes.
- Sampling: The module supports fast sampling rates of up to 40 Hz per channel, ensuring high-speed data capture for dynamic testing and monitoring.
“This new thermocouple module directly addresses the critical need for high-precision, multi-channel temperature monitoring in demanding industrial environments,” said Joe Holdsworth, Founder and CEO at Metis Engineering. “The combination of isolation, accuracy, and CAN bus integration makes it an ideal solution for applications where temperature monitoring is mission-critical.“
Seamless Integration and Robust Design
Metis Engineering designed the module for seamless integration and robust, industrial-grade operation. The built-in diagnostic and connectivity features simplify deployment and enhance system safety.
