依据GJB/z 377A-94感度试验用兰利法,对设计制作的不同桥区参数的Ni-Cr薄膜换能元进行了发火感度测试。结果显示:当桥区尺寸、形状一定时,随着桥膜厚度的增加,换能元的发火电压减小,当桥膜的厚度增加到0.9μm,换能元发火电压又有增加的趋势;当桥膜厚度、桥区形状一定时,随着桥区宽度减小,发火电压降低,但当桥区宽度小于0.10mm时,发火电压反而上升;当桥膜厚度、桥区宽度一定时,桥区长度越长,发火电压越高,而且不同桥区形状对换能元发火感度有明显的影响。
According to the GJB / z 377A-94 sensitivity test, the ignition susceptibility of Ni-Cr thin film transducer with different bridge parameters was tested. The results show that when the size and shape of the bridge zone are constant, the firing voltage of the transducing element decreases as the thickness of the bridging film increases. When the thickness of the bridging film increases to 0.9 μm, the firing voltage of the transducing element increases again. When the thickness of the bridge membrane and the shape of the bridge area are constant, the firing voltage decreases as the width of the bridge area decreases. However, when the width of the bridge area is less than 0.10 mm, the firing voltage increases instead. When the thickness of the bridge membrane and the width of the bridge area are constant, The longer the zone length, the higher the firing voltage, and the shape of the different bridge zones has a significant effect on the firing fluency of the transducing element.
