Introduction

DRFDS / DRFDN is a compact and accurate rotary torque transducer developed for production use. Available in 4 measuring ranges from 0.5 to 5Nm, the non-linearity is less than 0.15% and the temperature sensitivity is very low. The output signal is a frequency type (8 kHz +/- 2 kHz), whose variation is proportionally linear to the measured torque. An optional 360 pulses per revolution quadrature phase encoder transmits the angular position in high resolution.

Mounting and installation

The DRFDS / DRFDN sensor is powered by 12VDC. The DRFDN has a square shaft (DIN 3121-E or H 6,3), the DRFDS has a hexagonal shaft (DIN 3126-E or F 6,3). The hexagonal cross-section in accordance with DIN 3126 standard allows instant mounting on the tool or equipment to be checked. Dimensions
