Non-contacting torque sensor for power steering

TT Electronics’ Sensing and Control division has expanded its series of sensors for electronic power steering (EPS) applications.

The device, designated the Magnetorque Plus, combines a non-contacting torque sensor with a multi-turn position sensor in a single package.

The torque and position sensing functions are based on Hall…

Integrated sensor designs get benefit of fieldbus

Despite developments in sensor technology, the integration of a sensor within a larger systems device often results in a simple digital on/off signal. Whilst many applications would find this adequate, there is so much more that is possible by integrating the operation and configuration of sensors into the machine…

Digital colour sensing chip is tiny

Intersil has announced a light-in digital-out colour photometric chip.

Called ISL29125, and measures only 1.65×1.65mm, it is intended to be used alongside displays, monitoring ambient light so the perceived display colour and intensity can be maintained.

“Specifically, in OLED display TV applications, it can be used…

Honeywell designs high stability brushless motor sensor

Honeywell Sensing and Control has developed sensor technology for use in brushless DC (BLDC) motors which it says will remove the need for chopper stabilisation resulting.

The benefit of this is an improved response time, accuracy and reduced electrical noise without the need for additional filtering.

The technology is based…
