| 摘要 |
<p>The invention relates to an apparatus meant to measure the high frequency current intensity, 5.10^3 Hz - 27.10^6 Hz, without galvanic coupling, on a circuit having a high potential relatively to the earth, 10V - 10^5 V, destined to equip a research laboratory in the high frequency plasma field, high voltages field as well as in various industrial fields. The apparatus claimed by the invention consists of an interchangeable transducer (A), mounted on the tube (2), made of teflon, consisting of a quartz bulb (8) with a linear glowing wire (9) which converts the current intensity into a measurement circuit (13) in a proportional light spot, taken over and transmitted by a mobile condenser (14) and a diaphragm (b), on the surface of a photoresistor (15) coupled to an amplifier (17) in connection with an analogous micro-ampermeter (14).</p> |
