The BMT AC Current Sensor Clamp - 100A is a reliable and safe non-invasive current transformer (CT) sensor designed for measuring AC current without direct electrical contact. Using split-core transformer technology, this clamp easily attaches around a live conductor, eliminating the need for complex wiring or circuit interruption.
This sensor converts high AC current (up to 100A) into a small, measurable output signal, which can then be read by microcontrollers such as Arduino, ESP32, ESP8266, and other embedded systems. It is ideal for energy monitoring, power measurement, load detection, and electrical safety applications.
Thanks to its split-core design, installation is quick and convenient-simply clip it around the wire you want to measure. This makes it perfect for DIY energy monitoring systems in homes, offices, and industrial environments. The built-in resistor enables voltage output proportional to current, allowing easy integration into analog input systems.
With robust insulation, flame-retardant housing, and high dielectric strength, this sensor ensures safe and stable operation even in demanding environments.
