The CEDASPE NFG series (Normal Face Gauge) is a magnetic oil level indicator designed for both power transformers and large distribution transformers it is used for checking and measuring the oil level inside the conservator.
The outcome is an analogic indication given by an arrow spacing on a graduated dial and by one or more electric contacts (up to 4 switches) switching when oil reaches the minimum/maximum level allowed.
The gauge body is made of one piece of solid compact aluminum casting oil tightened proof.
The indicating system is located inside the body and is composed by an arrow, a graduated scale and the contacts activated by cams and a magnet system.
The monitoring system is located behind the fixing flange and is composed by a magnet coupling rigidly connected to a float arm which follows the movement of the surface of the oil either with a radial or an axial system.
CEDASPE NFG series has an IP65 protection degree, suitable for heavy-duty environmental conditions.
NFG series is even enable to be customized upon request: both body and dial can be designed according customer requirements.
