DC Current Sensor for Measuring Geomagnetically Induced Currents (GIC) in Electrical Grids and Distribution Networks

The CTH-GIC current sensor is designed to measure Geomagnetically Induced Currents (GICs) in electrical grids and distribution networks. It accurately detects DC currents in the presence of high AC levels, enabling reliable monitoring of GICs that can damage electrical distribution equipment. This non-contact, bidirectional sensor offers input/output isolation, making it ideal for grid applications and outdoor installations. Its split-core design allows for easy installation without interrupting the circuit.

DCFlex: Portable Wrap-Around DC Current Probe for Large DC Currents (1000A-100,000A)

DCFlex: Portable Wrap-Around DC Current Probe for Large DC Currents (1000A-100,000A)

The DCFlex is a lightweight, portable, and easy-to-use DC current probe designed for the measurement of large DC currents in industrial applications such as plating, chemical processes, and aluminum smelting plants. With a clip-around split-core design, the DCFlex is ideal for measuring DC currents from 1000A to 100,000A without the need for system shutdowns or the installation of shunts.

This versatile probe is suitable for single-shot measurements and provides accuracy better than 1%, traceable to international standards. It is powered by either batteries or an AC adapter, and it includes a handheld LCD display, making it convenient and efficient for both short-term and long-term monitoring of large DC currents.

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.

CTHsum Analog Summing Amplifiers / Summation Transducers

4-Channel Summation Transducers for 0-10V or 4-20mA Signals with Isolation Options

The CTHsum summing amplifier is a versatile and high-performance solution for summing analog signals such as voltage, current, energy, or power. It supports up to four input channels, allowing you to combine signals from multiple transducers or transmitters into one summation output. Ideal for applications where power or current summation is required, such as three-phase monitoring, plant consumption, or combining signals from multiple locations.
