An integrally mounted optical encoder option provides additional angular position measurement to 0.09 degrees with rotational speed feedback. The 8661 series is available in a wide choice of torque measurement ranges and is supplied complete with integral shaft drive assemblies; or for higher speeds and higher torque use, with adapters for direct mount on the mechanical structure to be measured.
The high resolution sensor features a 16-bit D/A converter and metal film strain gauges. A choice of output includes 0 to 10Vdc or USB, which is used with supplied PC software to allow users to directly read information in a dedicated GUI. The analogue output version is fully compatible with Burster and other manufacturers displays whilst the USB option is particularly useful for portable field-based measurement. A three-LED display provides operational status information.
Angle encoder options include 1024 or 400 line quadrature encoders with TTL level output for 0.225 or 0.09 degree resolution. Torque-only versions can be used at speeds to 25,000 rpm whilst encoder versions are limited to 6,000 or 15,000 rpm.
