PROTECTION UNIT OF A SURVEY METER AND HIGH RANGE GAMMA RAY SURVEY METER INCLUDING THE PROTECTION UNIT

摘要

PURPOSE: A survey meter electronic circuit protection element and a high-level gamma ray survey meter with the same are provided to prevent causes of malfunction causes of a high-level gamma ray survey meter in advance, thereby reducing costs required for maintenance and repairmen. CONSTITUTION: A survey meter electronic circuit protection element comprises an insulator(110), an elastic stainless board(120), and a cable hole(130). The insulator prevents electricity flowing in other parts of a survey meter except for a signal transmitting cable. The elastic stainless board formed with elastic stainless steel connects the insulator and a cable latch of the survey meter. When a protection element is inserted into a high-level gamma ray survey meter, the signal transmitting cable passes through the cable hole. The protection member is formed with a silicon material.
