Transducer Testing
Accuracy, Efficiency, and Automation in Electrical Transducer Testing
Electrical transducers are fundamental devices in measurement and control systems, responsible for converting quantities such as voltage, current, and frequency into standardized low-level signals—typically in the range of 0 to 10 Vdc or 4 to 20 mAdc. These signals are used by supervisory systems, controllers, relays, and data acquisition units for decision-making, equipment operation, and data logging.
Given the essential role transducers play in electrical and industrial systems, it is crucial to perform periodic verification and calibration tests on these devices. The accuracy and stability of the output signals are critical for the reliability of the entire system, and failures can compromise operation, trigger false alarms, or even cause unwanted shutdowns of loads and equipment.
The Importance of Transducer Calibration
The use of transducers in protection, measurement, and automation systems is widespread across various industrial segments and the power sector. These devices are applied in:
- Electrical substations;
- Industrial plant monitoring systems;
- Motor and generator control;
- Automated production lines;
- Data acquisition and telemetry systems.
Over time and under different operating conditions, transducers may show deviations in the converted values. This makes periodic calibration essential to ensure metrological traceability, according to technical standards and regulations in the electrical and industrial sectors.
