DC Current Sensors, Transducers, & Probes

DC Current Sensors for Industrial, Automation, Rail Transport, Welders, DCS, and Electric Vehicles Converting DC Current to Isolated Voltage or Current Loop with Optional Interfaces

The CTH DC current sensors offer precise measurement and conversion of DC current into isolated voltage or current loop outputs. These sensors provide instantaneous, accurate reproduction of the measured current, whether AC or DC. They are designed for a variety of applications, including electric vehicles, process control systems, welders, rail transport, DCS, and industrial automation. Available in through-hole or split-core options, the CTH sensors are non-intrusive and easy to install, covering a wide input range from 1A to 40,000Adc. With optional DC offset control to null residual DC currents and wide-range power input options, these sensors can seamlessly integrate into PLC, SCADA, transportation, and telecommunications systems.
