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
