Elettrotec level sensors equipped with a 4/20mA signal converter, have been designed to check continuously the level of a fluid in a tank.
Fixed over the tank containing the fluid to be checked, these sensors send a variable signal, according to the fluid level, by means of a linear transducer housed inside the stem along which the float with magnet slides.
By feeding the converter with a direct, filtered and stabilized voltage level variations ranging between 4 mA for the minimum level and 20 mA for the maximum level can be sensed. It is possible to program one or more alarm points connecting the sensor equipped with the converter to a personal computer or directly to one of the Elettrotec digital indicators.
To connect the level sensor to the digital indicators it is necessary to use a thin shielded cable with a 0.25 sq. mm section, taking out before the terminal board located under the C connector, by unscrewing the V screw.
To check turbulent fluids, it is recommended to use a slosh shield of the same length, with a 60 mm minimum internal diameter.
N.B. - The sensor must be placed at least 50 mm far from metal walls and possible interacting magnetic fields.
