FAQs
Q
What does the RSM-RLT(C) actually measure and where is it used?
+
A
It uses the magnetic logging method with a high-precision 3D magnetoresistive probe to measure the length of reinforcement cages—including joint positions—in cast-in-place concrete piles and prestressed pipe piles, providing fast, repeatable, and intuitive results.
Q
What are the key specs that impact field performance?
+
A
Depth resolution is < 0.1 cm with depth error better than 0.5% FS, maximum testing depth 150 m, minimum sampling interval 50 mm, and sensor resolution better than 50 nT (range ±200,000 nT). The system operates about 6 hours on a detachable lithium battery and works from -10 ℃ to +55 ℃.
Q
How portable and efficient is it on site?
+
A
The compact host (approx. 2 kg, 265×200×56 mm) and winch are easy to carry. A built-in slip ring enables real-time sampling while winding, and bidirectional detection helps distinguish changes in main reinforcement count. The 8.4" industrial-grade capacitive screen keeps signals clear under varied lighting.
