Device for measuring dimensions optoelectronics of high precision

摘要

P a.dispositif dimensional measurement optoelectronics of high precision to cancel the effect of the mechanical play of the movable rod of the sensor in contact with the workpiece to be controlled. / p & & p & b.le device comprises: 1un sensor of small dimensions in the case of which are integrated a source of application, two other adjacent photoreceptors, a moving shield bound to the movable rod into contact with the workpiece to be controlled, as well as the assembly 10 - receiver "electronique" carried out in a hybrid circuit, for example; 2une regulated electrical power supply voltage external to the sensor which allows its use, either to carry out the measurements with an indicator electrical a needle or digital, or to a control of the moving body displacements machines - tools. / p & & p & c.controles for mechanical and dimensional measurements of very high precision. / p
