[email protected] Design, Function Technical Data Design and Function The linear measuring scales consists of a hard chrome-plated steel rod and an enclosed plastic measuring head made from durethan bkv 30h6011. They differ in the obtainable resolution of 0.1 mm for the GEL 220 and 0.01 mm for the GEL 221. The distance is measured through the housing wall, the measuring system operating with semiconductors which are controlled by magnetic fields. Signal pattern VN Signal pattern V consists of two sinusoidal signals which are displaced by 90° and converted into square waves. These are output on two channels. The reference signal is output on the third channel, with its position and length being defined by the output signal. The outputs are designed as push-pull stages and they are sustained short-circuit-proof.
