Speed & Acceleration Transducer With Signal Conditioner Model PCT 109

The need to measure and analyze the vibrations producing in the most different structures recently brought to the development of proper transducers transforming the mechanical accelerations into electrical signals. Sci-tech Speed & Acceleration Transducer with Signal Conditioner Model PCT 109 has been designed to enable the student to develop the experiments on the subjects concerning speed and acceleration transducers and the related circuits for signal conditioning.

Item Description

Sci-tech Speed & Acceleration Transducer with Signal Conditioner Model PCT 109 has been designed with components and circuits really employed in Industrial Process Controls. With it, the
student can carry out experiments including a wide range of subjects concerning “speed” and “acceleration” transducers. The experimentation completes the theoretical background of the
student and gets him acquainted with the problems of professional practice. The external unit mod. TY28/EV, coming with the Sci-tech Speed & Acceleration Transducer with Signal Conditioner
Model PCT 109 and connectable to it via an 8-pole DIN cable, includes:
• Variable speed DC motor
• Connecting rod-crank system
• Speed and acceleration transducers
