Quick Overview
PROFILE- AND ROD-STYLE ABSOLUTE POSITION AND VELOCITY SENSOR
Stroke Length: 1 to 300 in (25 to 7600 mm)For position measurement, the absolute, linear Temposonics® position sensors make use of the properties offered by the specially designed magnetostrictive waveguide. Inside the sensor a torsional strain pulse is induced in the waveguide by momentary interaction of two magnetic fields. The interaction between these two magnetic fields produces a strain pulse, which is detected by the electronics at the head of the sensor. One field is produced by a moving position magnet, which travels along the sensor rod with the waveguide inside. The other field is generated by a current pulse applied to the waveguide. The position of the moving magnet is determined precisely by measuring the time elapsed between the application of the current pulse and the arrival of the strain pulse at the sensor head. The result is a reliable position measurement with high accuracy and repeatability.
Temposonics® position sensors fulfil the requirements of the Ethernet POWERLINK Standardization Group (ESPG). Ethernet POWERLINK V2 is an open protocol based on the Ethernet-standard according to IEEE 802.3. It is an extension to the Ethernet protocol which allows real-time data communication. Within the Ethernet POWERLINK protocol a CANopen based communication protocol for user data is specified. POWERLINK is the only Ethernet protocol that meets hard real-time requirements with a software-only concept. No special POWERLINK hardware is needed.
