ABB Current Sensors
ABB current sensors are precision devices designed to measure AC and DC currents with high accuracy in power distribution, instrumentation, automation, and control applications. ABB aims their current sensors at critical applications such as smart grid monitoring, drives, machine safety, process management, energy metering, and building automation. Current and voltage sensing is a significant product focus for ABB. They manufacture a wide range of component-level sensors as well as solutions that integrate measurement, control, and protective functions. Their key sensor technologies include Hall-effect transducers, Rogowski coils, transformer-based current sensors, and intelligent sensor modules with CANopen or MODBUS interfaces for direct digital integration.
In sensitive or harsh environments, ABB differentiates on stability over time, resistance to electrical noise, wide operating temperature ranges, compact footprint, and low power loss. Accurate and real-time current measurements are important for many energy-management applications. ABB designs their sensors to interface easily with PLCs, inverters, relays, switchgear, submeters, and SCADA or IoT communication devices. Sub-second response, low temperature drift, and high immunity to common-mode noise and harmonics make the units suitable for AC loads with rapidly-changing or pulsed profiles, as well as DC links in power converters.
