Slimsensor: Flexible, retrofittable current sensor

Sentec’s SlimSensor™ technology is a groundbreaking approach to current sensing that delivers high accuracy in an ultra-compact, low-profile form. Designed for seamless integration into space-constrained environments, SlimSensor™ is ideal for applications in network distribution low voltage substations.

SlimSensor is a flexible Rogowski current sensor that delivers superior signal-to-noise ratio, industry-leading accuracy, and does not require central mounting on the conductor. Compared to typical rope-style Rogowski sensors, SlimSensor offers three times the signal strength. Its innovative design is highly resistant to interference from AC magnetic fields generated by nearby conductors, enabling precise performance even when installed within tightly packed bundles—such as those found in low-voltage substations. SlimSensor is easy to fit one-handed, and its unique cable connection ensures correct orientation every time. It meets the most stringent accuracy standards, complies with all relevant safety regulations, and is designed for straightforward, cost-effective manufacturing.

SlimSensor™ is available for licensing, offering partners a unique opportunity to differentiate their products with cutting-edge sensing capabilities.
