Kyowa ASD-B-2KV ASD-B Acceleration Transducer for Crash Test
Made in Japan
Manufacturer: Kyowa Electronic Instruments Co., Ltd.
Model: ASD-B-2KV
The ASD-B is a compact and lightweight undamped acceleration transducer adopting a sputter strain gage for the sensing element. It is suitable for measurement of acceleration given to a car body or dummy in automotive crash tests. Considering that 3 units may be used for simultaneous measurement of acceleration in 3 directions. The ASD-B provides the centroid at the tip of mainframe so that 3 units are arranged with their vibration centroids put nearby.
Features
• High output
• Equips the dedicated connector for connecting the data acquisition system for crash test directly.
• Centroid is set at the tip of mainframe for triaxial configuration of acceleration transducers.
