Le prove sono state eseguite con solenoidi a temperatura di regime,<br />

sottoalimentati del 10% rispetto al valore nominale e con temperatura del<br />

fluido di 40°. Fluido impiegato: olio minerale con viscosità 45 mm 2 /s a 40°C.<br />

The tests were carried out with the solenoids at their working temperature,<br />

with a supply voltage 10% below nominal value and with a 40°C fluid<br />

temperature. The fluid used is a mineral oil with viscosity of 45 mm 2 /s<br />
