MTS Systems Corp., Sensors Division has developed new technology for their Temposonics® sensor that includes both an incremental interface and absolute output, such as Synchronous Serial Interface (SSI), in a single sensor housing. This configuration will allow for more precise position and speed control in linear motion by providing feedback to both the drive and the motion controller. The technology is expected to be launched with a new product in the first half of 2012.

“A dual-function sensor is something our customers have been asking for in a magnetostrictive linear positioning product for some time,” Matt Hankinson, Technical Marketing manager, MTS Sensors, explained. “Currently, designers using an incremental encoder who want to add absolute position feedback must add an additional linear encoder or use a proprietary interface. The new dual sensor will provide both an incremental quadrature signal to the drive and an absolute linear position feedback for motion control with a single sensor.”

An example of a potential application is a linear motor that would normally use an incremental linear encoder for drive commutation (switching current in phases to drive the motor position and speed). With this solution, a single sensor with two channels would have an incremental signal for driving the motor position while providing an absolute linear position feedback channel to the motion controller.

The new product will work at two levels. The incremental interface measures change in position while the SSI output communicates the absolute position of the sensor. Absolute positioning means there is never a need for calibration. Combined with the non-contact sensor technology used in all MTS Sensor products, this can dramatically decrease installation and maintenance costs in these applications while boosting productivity. Additionally, this inherently absolute position technology does not “lose track” of its position regardless of traverse speed.
