无触点覆盖开关

CONTACTLESS COVERAGE SWITCH

覆盖开关是地震勘探的重要设备,但是,目前国内外所用的覆盖开关全都是有触点的机械开关,由于它存在缺点甚多,就不大适应当前数字化的要求。 无触点覆盖开关是根据新设计的“场效应管矩阵网络”来实现的。由于它克服了机械开关的缺点,所以曾得到野外人员的欢迎。

’ The contactless coverage switch is an important device for seismic prospecting. At present,however,all of the coverage switches used both at home and abroad are contact mechanical ones. They cannot, more or less, meet the requirements of current digitalization of seismic data enhancement’in consequence of a good fews disadvantages existing in practice.The contactless coverage switch is developed in accordance with the newly designed "field effect transistor matrix network" .As it had overcome all the disadvantages of the previous mechanical switches,the iield personnel concerned are pleased to use it with great satisfactior.
