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.


Conprove Solution for Transducer Testing

To meet this demand with precision, practicality, and reliability, Conprove offers the market a dedicated software for transducer testing. This software provides full control of the CE-6707 and CE-6710 universal testers, enabling signal generation and verification with high accuracy, low distortion, and a wide operating range.

The software interface is designed to simplify the calibration process, offering tools that allow:

  • Generation of voltage, current, and frequency signals with adjustable values;
  • Accurate verification of the transducer’s low-level output signal (voltage or current);
  • Linearity and dynamic response analysis of the device under test;
  • Automatic result recording and generation of technical reports;
  • Comparison with reference values and calculation of percentage deviations.

This solution is ideal for use in calibration laboratories as well as field maintenance in industrial settings or by utility companies.
