Rezumat:

A novel design for a mechanical-electrical transducer is presented in this article along with the reliminary testing of the transducer prototype. By using a Polaroid optocoupler as the motion sensor, this device combines the transducer feature to convert mechanical signals to electrical ones with the optoisolator feature of galvanic separation between two voltage modules. Signal conditioning
circuit is a current-to-frequency converter, while the obtained signals are logically compatible and can be processed by a microprocessor. The device is aimed for application in the
areas of automation and mechatronics.
