Temposonics linear-position sensors use the time-based magnetostrictive position sensing principle developed by MTS. Within the sensing element, a sonic-strain pulse is induced in a specially designed magnetostrictive waveguide by the momentary interaction of two magnetic fields. One field comes from a movable permanent magnet that passes along the outside of the sensor. The other field comes from an “interrogation” current pulse applied along the waveguide. The resulting strain pulse travels at sonic speed along the waveguide and is detected at the head of the sensing element.
The position of the magnet is determined with high precision and speed by accurately measuring the elapsed time between the application of the interrogation pulse and the arrival of the resulting strain pulse with a high-speed counter. The elapsed time measurement is directly proportional to the position of the permanent magnet and is an absolute value. Therefore, the sensor's output signal corresponds to absolute position, instead of incremental, and never requires recalibration or re-homing after a power loss. Absolute, non-contact sensing eliminates wear, and guarantees the best durability and output repeatability.
Temposonics R-Series EtherCAT sensors represent MTS Sensors’ development and product offering in high-speed networked position feedback. EtherCAT (Ethernet for Control Automation Technology) is a unique interface developed by Beckhoff Automation and is supported by the EtherCAT Technology Group (ETG).
This interface is used for industrial Ethernet, providing the fastest, most deterministic industrial networking solution possible using the base Ethernet physical layer. By using this format, coupled with our high speed networked sensing capability, machine builders and automation engineers will be able to overcome bandwidth and node limitation issues found with other commercially available industrial networks.
