In electromagnetic and magnetic testing, varying magnetic field produced around a conductor by alternating current flowing in the conductor.
Alkali ion diode, английский
Sensor type for halogen gases. in this device, positive ions (cations) of an alkali metal are produced on the heated surfaces (usually platinum) of the diode. one electrode is at a negative potential and attracts cations that are released when a halogen gas passes between the sensor electrodes. provides an output current to operate the indicator on the halogen leak detector.
