Abstract

The detector includes a contact probe 1 connected via a discharge tube 3 and capacitor 3/1 to an earth 2 which co-operates capacitively with the ground, a power source 4 supplying a voltage converter, and a luminous discharge tube 6. Main electrodes 6/1 and 6/2 of tube 6 are subject to a DC voltage stored in capacitor 5/5 and a control electrode 6/3 is connected to a relaxation circuit 7/1-7/4. The voltage converter charges capacitors 5/5 and 7/1 and comprises an oscillator having switching transistors 5/1 and 5/2 and a step-up transformer 5/3 5/4 giving an output rectified by diode 5/6. The oscillator is only triggered by input voltage to probe 1 thereby to trigger tube 6 and provide a light signal which also blocks the oscillator until a new cycle of operation. Current consumption when quiescent is negligible. An additional acoustic warning device may also be provided.
