Torque measurement is usually carried out using the well proven bonded strain gauge technique, the shaft clamping torque sensing beam method is also available as an alternative. Digital encoding of measurements and PCM data transmission ensure reliable operation and accuracy to 16 bits (1 part in 64,000). The rugged split-ring shaft assemblies are custom fabricated according to shaft diameter and additional remote displays can be incorporated as required. A USB port enables connection of a laptop for ships trials and other specialised tasks.
