EBx7800 Sensors Solution for Highspeed Measurement

The sensor modules in the EBx7800 family are FixPitch sensor modules based on the Giant MagnetoResistive (GMR) effect. The sensor modules were developed specifically for use in ferromagnetic tooth structures. A magnet is therefore integrated into every sensor module to stimulate the tooth structure.
This operating principle allows existing machine elements, such as gear wheels or threaded spindles, to be used as measurement scales. These must have a ferromagnetic material property and must have a tooth pitch that matches the sensor pitch.
No specific tooth forms are required. This also allows the sensors to be operated on a hole structure or a square tooth structure.
The sensor signals of the sensor modules are processed in an ASIC and can be used directly from the controller. The modules are set by us during production and are optimally calibrated.
The programming and calibration tool "FOCUS" was specially developed to easily recalibrate the EBR7811 sensor modules in the customer application and also to change settings on the module.
The tool offers an automatic calibration process and, by means of clear PC software, also a logging function of the calibration process - this is particularly suitable for calibrating the module in production or at customer service.
