Made in Japan
Manufacturer: Kyowa Electronic Instruments Co., Ltd.
Model: BRD-10AT
The BRD-AT is a displacement transducer with thermal sensor. It is suitable for compressive changes of rock-bed and enables measurement of upheaval.
Features
• Detect relative displacement between the ground surface and the anchor fixed to the bottom of a boring
• For displacement detection, the joint transducer BJ-AT is required.
• For rock-bed grout management
