  • SF6 concentration sensor for gas-insulated electrical

    Feb 01, 2014Reaching the envisaged accuracies is a challenge for commercial density sensors which are designed for tracking SF 6 densities of 40 kg m −3 and higher at much lower absolute accuracies than required here. For that reason, the density sensors needed to be calibrated in-house to make them suitable for pTρCited by: 7
