Non-contact precision sensor measures torque and speed

Ixthus Instrumentation Ltdvisit website


Ixthus Instrumentation is launching new Burster 8661 series non-contact precision torque sensors with optional measurement of shaft angle and speed. The new 8661 series provides precise and convenient measurement of static and bidirectional rotating torques from 0-0.05Nm to 0-200Nm, with full-scale accuracy to 0.05 per cent, for analysing breakaway, holding and tightening torques in mechanical power applications across manufacturing quality control, field service investigation, and research and development. An integral optical encoder option provides additional angular position measurement to 0.09 degrees with rotational speed feedback - making the 8661 sensor a useful test or calibration tool for precision micro-mechanics, electric motor test beds, bearing test stands or wherever combined torque and angular position characteristics need to be measured reliably and securely.

Ixthus offers the 8661 series in a wide choice of torque measurement ranges and the sensors are supplied complete with integral shaft drive assemblies; for higher speeds and higher torques, they are supplied with adapters for direct mounting 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 0-10V DC or USB, the latter of which is used with the supplied PC software to enable users to directly read information in a dedicated GUI. The analogue output version is fully compatible with Burster's and other manufacturers' displays, while 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 25,000rpm while encoder versions are limited to 6000 or 15,000rpm.

With a 10–30V DC rated supply voltage, the 8661 has a 12-pin electrical connector and accessories include mating straight or right-angled connectors and cable assemblies to suit Burster display instrumentation.
