BRD-AT
Rock-bed Compression Displacement Transducer

Summary

The BRD-AT is a displacement transducer with thermal sensor. It is suitable for compressive changes of rock-bed and enables measurement of upheaval.
Rated Capacity: 5 to 50 mm, -30 to 70ºC
Nonlinearity: Within ±1.5% RO
Rated Output: 1 mV/V or more

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
