Electrical Measuring Transducer Rotational Speed Sensor FP Series

FP series electrical measuring transducer

1. Summarize

GP. EP series transducer ( they have same function and accuracy ) ,adopting completely import scattered unit , include ASIC chip ( special thick – filmcircuit ). Ultralinear voltage and current mutual inductor etc., it packaging produced according to the international quality assured system ISO9001: 2000 ,it has multi specification , The GP , EPseries have different specification s , including voltage , current , active/ reactive power , active/ reactive energy , frequency , power factor , negative voltage , and negative current , etc. they have higher integration , working more reliability , good temperature characteristic and long-term stability , nice electric impact immunity and over load ability , higher precision and linearity , the third generation transducer needn’t checking and servicing frequently , it can be trusted absolutely .

GP, FP series meet IEC , ANSI , BEAMA and other related criterions , it achieved advanced level in the international .

FP series transducer have get national measuring instruments’ produce licence , and has passed quality detection , it used widely in national major electric power project and electric dispatching system .
