SC0073压电薄膜脉搏传感器,该传感器采用电压复合材料作为换能元件,信号通过特殊的匹配层传递到换能元件上变成电荷量,再经传感器内部放大电路转换成电压信号输出。
它是一种高性能低成本的振动传感器,具有灵敏度高,频率响范围宽,抗过载及冲击能力强,搞干性好,操作简便等,具有良好的低频响应,可以方便地测试低频振动,颈动脉波,心尖搏动波及其它体表动脉的搏动波。
此R6828产品为Hamamatsu日本公司生产, R2868 is a UV TRON ultraviolet detector that makes use of the photoelectric effect of metal and the gas multiplication effect. It has a narrow spectral sensitivity of 185 to 260 nm, being completely insensitive to visible light. Unlike semiconductor detectors, it does not require optical visible-cut filters, thus making it easy to use. In spite of its small size, the R2868 has wide angular sensitivity (directivity) and can reliably and quickly detect weak ultraviolet radiations emitted from flame due to use of the metal plate cathode (eg. it can detect the flame of a cigarette lighter at a distance of more than 5 m.). The R2868 is well suited for use in flame detectors and fire alarms, and also in detection of invisible discharge phenomena such as corona discharge of high-voltage transmission lines. ★ Flame detectors for gas/oil lighters and matches ★ Fire alarms ★ Combustion monitors for burners ★ Inspection of ultra...
