WPA-F and WRA-F, the first position sensors with HYPERWAVE magnetostrictive technology and PROFINET connectivity, available with RT (Real-Time Ethernet) or Synchronised IRT (Isochronous Real Time) transmission protocol.
The new transducers are characterised by the capability to simultaneously detect the position and speed of up to 16 independent cursors over a stroke of 4,000 mm, with a position reading update rate of 4kHz, i.e. over 4,000 times per second, for a precise position reading with the highest degree of repeatability. Among the new features of the WPA-F and WRA-F models, both cULus certified, those standing out are the diagnostic functions designed at communicating, for example, anomalies in the power supply system, the reaching of temperatures out of range, the incorrect parameterisation at start-up, the possible lost communication between the electronics and the sensing element or, further, the absence of a magnetic cursor inside the work area. Finally, the transducer’s actual operating time and the actual and maximum temperature reached, can be monitored.
“The new PROFINET certified sensors, with Encoder profile vr.4.2., are enriched with new and better performing features while maintaining the advantages of the Hyperwave series which continues to stand out for a resolution of less than 0.5 microns and a very low linearity error, equal to 0.01%/FS”, comments Edoardo Zilioli, Gefran Sensors Marketing Manager, who continues: “A further strength is how easily our solutions are implemented: PROFINET transducers are designed to ensure maximum compatibility with the entire HYPERWAVE family range, as well as with the current market offer.”
