Explain the principle and operation of the talysurf surface meter
- Talysurf is used to measure the surface roughness by using an electronic principle, this surface meter consist of stylus and skid type instrument used for measuring the surface of the give product.
- This type of talysurf surface meter contains an Electronic means which is exact and high accurate than different types of surface meter.
- The measuring head consist of sharply pointed diamond stylus on it. in talysurf surface meter stylus has a very small radius of 0.002 mm tip and with the help of motor present in it helps to move the skid on the surface.
- In this instrument, the stylus point out’s the profile of the surface and any deflections of a stylus is converted into electric current to identify the measurements of the object.
- It consist of stamping above the armature which consist of coils on both the sides of stamping, this coils helps to forms an oscillator. In this surface meter the armature present on the stamping is in fixed position when this fixed armature causes any vibrations of stylus it produces an air gap by this the current passing from a coil get changed due to this changes in the amplitude of current the output gets to demodulate due to this discontinuous current passing the measurement of surface is given by an electronic system present in it.
