The growing necessity to keep under control the power consumptions needs a device making fast and reliable data acquisition even at a distance: measuring transducers assures these requirements.
The transducers measure electric variables on the energy production and distribution network and give a signal proportional to the measured value. This signal can be sent to several instruments (digital or analog meters, recorders etc.) connected in series.

The adoption of the latest generation microprocessors, the carefully dimensioned transformers (resin insulated), the careful choice of UL recognized components and materials (printed circuit boards, connectors, cases, etc.) and the calibration with ACCREDIA certificated instruments, guarantees to ESAM transducers the highest precision and reliability in every condition of use.

Each transducer is equipped with a label giving the model, the wire diagram and technical data.

The whole ESAM production complies with CE standards.
