摘要:
基于韦根特效应制成的零功耗磁敏传感器是一种新颖的器件,它在一定磁场的作用下无需外加电源,就可以输出幅度和宽度都恒定的电脉冲信号,并且脉冲的幅度在1V以上.这种特性为电子水表、电子热能表等的开发提供了不少有利的条件.在介绍这种传感器的原理、结构、性能和特点的基础上,介绍了基于此传感器的电子水表基表的研制过程.通过对水表基表产生的脉冲信号进行处理和编写相关的程序软件就可构成完整意义上的电子水表.对其进行实际测量和使用表明:该水表具有零功耗、零响应频率、结构简单、可靠性好等优点.
Abstract:
As a new type of apparatus, zero pow er dissipa tion m agnetic- sensitive senso rwh ich is developed based on W iegand effect, can br ing about e lec tric pulses of invariable amp litude and w idth, and the am plitude of the pluses exceeds 1 Vo lt w ithout needing extra e lectr ic pow er in the e ffect o f certa in m agnetic fie ld. Th is spec ial feature prov ides m any advantages fo r the deve lopm ent o f e lectron icwa ter-m ete r or the rma-lm e ter. The pr inciple, structure and characters o f th is zero pow ered m agne tic-sensitive senso r are introduced in this paper. Based on th is sensor, an electronic essentia-l wa ter-m eter is deve loped. H av ing dea lt w ith the pu lse signa ls g enerated o f the me ter and com p iled the re lev ant prog ram softw are, w e can construct a w ater-me ter in a comp le te sense. The resu lts o f practica lm easure and app lications indicate that this w ater-m e ter has the characte ristics o f zero pow er d issipation, zero responding frequency, sim ple structure and h igh re liability.
