Spherosyn MS S2G measuring strip - 1930 mm The Spherosyn (MS S2G) and Microsyn (MS M2G) length measuring systems are specially designed to meet the demands of the harsh workshop environment. Advantages IP67 rated - fully retractable Impervious to coolants, oil, dust, chips and almost all workshop influences No more broken or scratched glass Tolerant to vibration and magnetic interference No need for regular maintenance or cleaning No mechanical wear and tear Lifetime warranty on the scale More than 400,000 Spherosyn and Microsyn transducers worldwide offer the highest level of reliability. Spherosyn and Microsyn transducers can not only be used in the DP700 digital position display, but can also be integrated into various feedback applications such as CNC systems and PLCs. How it works Spherosyn and Microsyn scales are based on the principle of electromagnetism and consist of a stainless steel or carbon fiber tube filled with individually graded high-precision steel balls. The beads are placed in the tube at a controlled temperature and calibrated. The readout head consists of six coils that are wound around a composite fiber spool. The coils and the required electronic circuitry are encapsulated inside the readhead using a special molding process. Applying a voltage to the coil creates an electromagnetic field in the reading head. Due to the curvature of the balls inside the tube, the output signal varies depending on the position of the coils over the balls. As the reading head passes over the ruler, the relative axial motion generates corresponding signals that are induced on each probe coil.
