Top drive instrumentation

Reference :

Instrumentation for an oil-drilling SUB to measure and record the torque applied to the oil-drill bit.

Here, rather than provide a torque transducer to be integrated into a mechanical assembly, we directly instrument the customer's test body by glueing strain gauges on to particular areas.
In this case, we produced a multi-axial instrumentation which measures the torsion torque, the vertical force and the bending moments.

Specifications :

Measurement ranges :
- Rotation torque : 50 kNm
- Vertical force : 200 kN
- Bending moment : 10 kNm
Accuracy: ± 1 %
Material : Stainles steel
