DR-2208 / DR-2508

The DR-2208 and DR-2508 non-contacting, dual range torque transducers are active sensors with integrated measuring amplifiers. They offer a range of output signals: analog ±5V (standard), ±10V (optional) or digital outputs via RS485 or USB.

The non-contact transmission ensures maintenance-free data transfer between the rotor and stator, without signal distortion. Optional integrated speed and angle measurement is available for most non-contact models.

Mechanically, these transducers are available in two types: with bearings or bearingless. Bearingless models eliminate the risk of friction-induced measurement errors and are generally designed for higher rotational speeds.

Digital versions are divided into two categories based on their interfaces: RS485 and USB. RS485 transducers offer excellent noise immunity, even over long cable runs. USB transducers, on the other hand, require no additional measuring amplifiers. They connect directly to a standard PC via plug-and-play. Before first use, simply install the included USB driver along with the configuration and analysis software.

Typical applications include screw-driving systems and test bench applications like the evaluations of components such as engine, drivetrains, gears, bearings and seals — particularly in scenarios requiring high-speed continuous operation and standardized signal outputs.
