Current Sensor Transmitter | 0-100A to 4-20mA | Split Core Clamp

This QNDBK2-24 split core current sensor measures AC electricity use without needing to cut or strip wires. It converts current flow into a standard 4-20mA signal. This is useful for industrial current monitoring and connecting to PLCs or other control system inputs. Features and Benefits - Split-Core Design - The hinged body clamps directly around an existing wire. This lets you install the sensor without disconnecting wires or shutting down power. - 4-20mA Analog Output - It provides a common 4-20mA current output signal. This makes it easy to integrate with most industrial automation and data acquisition systems. - Multiple Current Ranges - Models are available for 1A, 5A, 10A, 20A, 50A, and 100A. You can match the sensor to your specific load for better accuracy. - Certified Performance - This current transducer has Class 1.0 accuracy and CE/RoHS certification. It gives readings you can trust for your applications. Applications - Industrial Automation - Monitor the power consumption of motors, conveyors, and other machinery. This helps detect operational issues. - Energy Submetering - Use it as a split core current transformer to track electricity use in different zones of a building or factory. - HVAC System Monitoring - Check the current draw of compressors, fans, and pumps. This helps ensure they are running efficiently. Common Sensing Methods A current sensor detects the flow of electrical current, converting it into a measurable output signal. There are two primary methods for sensing current: direct (resistive) sensing and indirect (magnetic or non-contact) sensing. Each method has distinct characteristics and is suited to different applications. Understanding these methods helps in selecting the appropriate specific sensor for a given task. Direct (Resistive) Sensing Direct current sensing involves placing a resistive element, often called a shunt resistor, directly in the path of the current to be measured. The voltage drop across this resistor is then measured, which is proportional to the current flowing through it according to Ohm's Law. This method is generally accurate for DC currents and lower AC currents but introduces a voltage drop in the circuit. It is not the method used by the Split Core Clamp Current Sensor Transmitter. Indirect (Magnetic / Non-Contact) Sensing Indirect current sensing, such as that employed by the Split Core Clamp Current Sensor Transmitter, does not require direct electrical contact with the conductor. Instead, it measures the magnetic field generated by the current flowing through the conductor. This specific sensor type uses a Split Core Current Transformer (CT) Transmitter. It allows for non-invasive measurement, meaning the circuit does not need to be broken to install the sensor. The sensor clamps around the conductor to detect current from 1A to 100A AC. Key Applications This Split Core Clamp Current Sensor Transmitter, with its 0-100A to 4-20mA output, is suitable for various industrial and commercial applications where AC current monitoring is required. The 4-20mA output signal is a standard in process control, enabling integration with PLCs, data loggers, and control systems. Its split-core design simplifies installation, making it ideal for retrofitting into existing electrical systems without disrupting operations. It can monitor input current ranges of 1A, 5A, 10A, 20A, 50A, and 100A AC.
