Wireless transmitter for force-torque sensors

Use the handy wireless transmitter SCHUNK FTW data on the 6-axis force-torque sensors SCHUNK FT-Nano and SCHUNK FT-Mini can be transmitted wirelessly to control systems or computer. The battery-powered transmitter can be for data collection, use the real-time control or for a custom signal processing. It allows first wireless use of force-torque sensors for mobile robots and platforms in service robotics or intralogistics.
The module is standardized in two sizes and can simultaneously transmit data from up to three or up to six sensors. Since communication on the proven IEEE 802.11a / b / g / n standard occurs (2.4 GHz or 5.0 GHz), the transmitter can be easily integrated into existing WLAN infrastructures. The typical signal range is 30 m in an office environment, outdoors up to 100 m are possible.
The Wireless Transmitter SCHUNK FTW can transfer data from up to six SCHUNK FT force-torque sensors wirelessly via WLAN.
The highly accurate Force Sensors SCHUNK FT series offer the opportunity to develop new applications - to dirt from intensive product testing sensitive surfaces through the use of robotic surgery as well, force controlled Entgratanwendungen. Since the sensors also allow highly dynamic control concepts, difficult assembly, machining and finishing tasks can be automated with themselves.
They enable distributed intelligence in the individual task and are suitable for monitoring of process parameters, for decentralized quality assurance and documentation of quality criteria. A total of 16 sizes for load ranges between 12 N and 40,000 N includes the SCHUNK FT series. They can be used in the force components Fx, Fy and Fz resolutions starting at 1/682 N and at the moment components Mx, My and Mz capture resolutions starting at 1 / 8,000 Nm. While conventional force-torque sensors operate with Folienmesstreifen, the FT sensors from SCHUNK are equipped throughout with silicon strain gauges. These provide a 75 times stronger signal than conventional sensor solutions, they have a linear measurement range and reduce signal noise to almost zero. In conjunction with the standard integrated temperature compensation, the high accuracy is maintained during the process and a large temperature span of time.
