Mechanical-electrical optoisolator transducers are position transducers which use as a sensor, a Polaroid optocoupler specialized in converting rotation and/or translation movements into electrical signals. The used sensor is an analog device whose transfer characteristic is non-linear. In this article is presented a method of linearizing this new type sensors’s characteristic. The method is based on the analysis of the physical processes which take place within the Polaroid optocoupler. The mechanical-electrical optoisolator transducer allows the extraction of the signals out of the areas with intense electromagnetic field. Being an analog linear transducer, the signal generated by it doesn’t impose the use of a microprocessor. This thing permits to obtain some systems of checking the position of a machine-tool’s components at a low cost price.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
