资料介绍

brüel&kj_r水听器是用于测量的传感器水声。

四个水听器是:

 •8103型微型水听器

 •8104型校准标准水听器

 •8105型球形水听器

 •8106型低噪声水听器

        一种小型传感器,相对于其尺寸具有高灵敏度和良好的综合特性;适用于实验室、工业和教育用途。例如,当测量超声波清洗槽中的压力分布时,其高频响应是有价值的。

P R O D U C T DATA  
Hydrophone Types 8103, 8104, 8105 and 8106  
Brüel & Kjær hydrophones are transducers for measuring  
waterborne sound. The four hydrophones are:  
• Miniature Hydrophone Type 8103  
• Calibration Standard Hydrophone Type 8104  
• Spherical Hydrophone Type 8105  
• Low-noise Hydrophone Type 8106  
Each hydrophone:  
• Is individually calibrated  
• Has a flat frequency response  
8105  
• Is omnidirectional over a wide frequency range  
• Is absolutely waterproof  
8103  
• Has a high resistance to corrosion  
• Is manufactured using lead-free nitrile butadiene rubber  
• Has shielded-element construction  
8104  
8106

double-shielded cable  
Miniature Hydrophone Type 8103  
A small-size transducer with a high sensitivity relative to its size and good all-  
round characteristics; applicable to laboratory, industrial and educational use. Its  
high-frequency response is valuable when measuring pressure-distribution  
patterns in ultrasonic-cleaning baths, for example.
