Electrical data loggers measure current and voltage using sensors and transducers that convert these electrical parameters into measurable signals. For current measurement, data loggers often use current transformers (CTs) or Hall effect sensors. CTs are used for AC current measurement and work by inducing a proportional current in a secondary winding, which the logger then measures. Hall effect sensors, suitable for both AC and DC, detect the magnetic field generated by the current flow and convert it into a voltage signal that the logger can process. For voltage measurement, data loggers typically use direct connections to the circuit. They employ voltage dividers or potential transformers to step down high voltages to a safer, measurable level. The logger's input channels are designed to handle these reduced voltages, converting them into digital signals using analog-to-digital converters (ADCs). This digital data is then stored for analysis. Data loggers are equipped with multiple channels to simultaneously measure different parameters. They often include features like signal conditioning to filter noise and improve accuracy. The collected data is timestamped and stored in internal memory or transmitted to a computer or cloud service for real-time monitoring and analysis.
