Interface Model 5400 Series Flange Style Reaction Torque Transducer

The Interface Model 5400 Series Flange Style Reaction Torque Transducer is a premium, high-stiffness static measurement instrument engineered to deliver highly repeatable torque data across high-capacity testing applications. Featuring a robust flange-to-flange mounting layout, the 5400 series is explicitly optimized to isolate true rotational twisting forces while operating under heavy extraneous loads, bending moments, and large overhung masses. It represents the definitive metrology benchmark across the UK for production quality testing of large rotary components, automotive drivetrain validations, aerospace actuator diagnostics, and industrial machine bed installations.

The primary mechanical advantage of the 5400 series architecture is its through-hole flanged structural hub. By mounting the transducer via several smaller peripheral fixing bolts rather than a single large central thread, engineers can easily achieve high-precision clamping preloads without needing massive structural wrenches. Machined as a shear-web sensing block, the design delivers an exceptionally high torsional stiffness profile matched to extremely low mechanical deflection. By bonding proprietary Interface strain gauges into an internally balanced Wheatstone bridge matrix, the device restricts maximum tracking errors to a strict ±0.1% FS nonlinearity across all standard capacities.
