DF-RTS Reference Torque Sensor 50-10,000 Nm | Stationary | Class 0.04 Accuracy (Optional 0.02)

Strain Gauges (DMS) | 50 – 10,000 N·m | Stationary Standard | PCD Flanges 84.0 – 196.0 mm

The DF-RTS (Reference Torque Sensor) series acts as the primary transfer standard for laboratories in DIN 51309 validation. Designed to enforce 1:1 type compatibility drop-in replacement Compared to historical references, its stainless steel matrix incorporates the stepped PCD flange standards (from 84.0 mm in DF1 to 196.0 mm in DF5). This dimensional modularity ensures that calibration departments can test the dynamometer's static mountings without making any mechanical modifications to the instrument being calibrated.

The readout core avoids parasitic fluctuations through extreme thermal compensation and direct transmission, inheriting the analytical perfection of inductive (dual-frequency) telemetry. This generates unquestionable EMI immunity in highly radiated environments, stabilizing the entire detection bridge. The ultimate metrological exponent of the spectrum of torque sensors ensures certificates without deviation in Gemisa.
