Yokogawa’s LS3300 AC power calibrator now comes with a harmonic output capability
High-precision 8-channel isolated thermocouple module for high- voltage industrial applications
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.
The thermocouple module measures temperatures across an exceptional range from -200°C to +1,800°C at sampling rates to 40Hz per channel. This capability makes it ideal for applications ranging from cryogenic research to high-temperature industrial processes.
Each channel is 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°C to 85°C and ±1°C from -40°C to 125°C, the module delivers reliable performance in the most challenging environments. 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 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.

Yokogawa Test & Measurement announces that its precision AC power calibrator, the LS3300, now has the optional function of added harmonic output. The LS3300 Precision AC Power Calibrator outputs highly accurate and stable power calibration signals — now including harmonics — for greater efficiency and productivity of power meter calibration workflows, making it the most versatile and user-friendly precision AC power calibrator in its class. This enables superimposed harmonic signals without degrading fundamental accuracy, up to the 51th harmonic (depending on configuration), and controlled phase, amplitude and frequency, among others.
Real-world AC power waveforms often exhibit distortion due to harmonics— integer multiples of the fundamental frequency—that can compromise power quality, leading to adverse effects in systems and components and, ultimately, their malfunction and even failure. As high-power electronic devices—inverters, drives, switching supplies, and others—become more widely used, especially in consumer and industrial applications, harmonic distortion becomes a growing concern. Harmonics lower energy efficiencies, cause overheating in electrical components and failures in sensitive equipment, shorten lifespans and lead to non-compliance with power quality standards such as IEEE and others, making it even more important to control and suppress them.
High-end power calibrators can generate harmonics to simulate real-world power conditions and enable accurate testing and calibration of power quality analyzers. However, they are costly and complex to operate. Basic calibrators and AC power supplies are suitable for fundamental frequency (e.g., 50/60 Hz) testing, but cannot provide traceable reference that includes accurate harmonic content. Overall, this calls for a practical, easy-to-use and cost-effective solution that can generate reliable AC waveforms with harmonic content, accurately. The enhanced LS3300 is a versatile instrument that provides stable and accurate outputs of voltage, current, and phase, thus helping to calibrate more types of devices with one compact instrument. For high volume testing it can be synchronized with other units, to emulate single or three-phase systems, further expanding the range of products to be calibrated to various standards, including the IEC. The Yokogawa LS3300 provides intelligent synchronization for three- phase output via a master/slave multi-unit system. Up to three units can be synchronized this way, to control various settings. The setup enables the calibration of three-phase AC power measurement devices and supports high-current applications up to 180A. With the LS3300, metrology labs and calibration teams can meet increasingly strict power quality testing demands, improve productivity and ROI by not using separate harmonic generators, and comply with current and future compliance specifications and standards. They are also enabled to offer more comprehensive services without having to upgrade to bulky, complex, high-end systems.
