Bristol-based Metis Engineering, a developer of advanced CAN-based sensor technology, launched its new 8-Channel Isolated Thermocouple to CAN module, that addresses temperature monitoring requirements of industrial, automotive and research applications.
Each channel isolated to 1000VDC making the new device a significant advancement in thermocouple technology. Offering unparalleled precision with an accuracy of ±0.5°C from 0 to 85°C and ±1°C from -40 to 125°C, the module delivers reliable performance in the most challenging environments.
The thermocouple module measures temperatures across an exceptional range from -200°C to +1,800°C at sampling rates of up to 40Hz per channel. This capability makes it ideal for applications ranging from cryogenic research to high-temperature industrial processes.
Each channel features galvanic isolation exceeding 1000VDC, enabling safe and accurate temperature measurement in high-voltage systems such as battery packs, power electronics, and electric vehicle components. This isolation eliminates current paths through thermocouple leads, ensuring reliable measurement accuracy by preventing ground loops and electrical interference that can compromise temperature readings.
“The combination of isolation, accuracy, and CAN bus integration makes it an ideal solution for applications where temperature monitoring is mission-critical,” said Joe Holdsworth, founder and CEO at Metis Engineering.
The device features comprehensive fault detection capabilities, including open-circuit and short-circuit detection that alerts users when thermocouple wires are broken, disconnected, or shorted to ground or power. This built-in diagnostic functionality ensures system reliability and reduces maintenance overhead.
Engineered for harsh industrial environments, the module with potted electronics features DIN rail mounting and IP67-rated JWPF connectors that enable daisy-chaining with additional modules for expanded measurement capabilities. The robust design supports input supply voltages from 9 to 32V, making it compatible with a wide range of industrial power systems.
The device ships with K-type miniature thermocouple connectors as standard, with support for multiple thermocouple types including K, J, T, N, S, E, B, and R configurations. This flexibility allows users to select the optimal thermocouple type for their specific application requirements.
The module’s configurable CAN bus speed and address, combined with the supplied DBC file, enables straightforward integration into existing CAN networks. This feature is particularly valuable for automotive applications and industrial automation systems where CAN bus communication is standard.
“The CAN bus integration reflects our commitment to providing sensors that integrate seamlessly into modern industrial and automotive systems,” added Holdsworth. “Engineers can quickly deploy multiple channels of high-precision temperature monitoring without complex integration challenges.”
