<p>To fit capacitive surface electrodes to a transducer for magnetic induction flowmeters which comprises an electrically-insulating graduated ceramic tube with vitrified metallic measurement electrodes, metal grids (2) made of platinum are embedded and vitrified in a leakproof manner in the ceramic material of the measurement tube (1). These metal grids (2) are provided with connection wires (5) projecting from the tube jacket and are also vitrified in a leakproof manner in the ceramic material.</p> |
