Linear and angular displacement electromagnetic sensors

Domenii publicaţii > Fizica + Tipuri publicaţii > Articol în volumul unei conferinţe

Autori: Lozovan M., Dobrea V., Velicu S., Corabieru P., Iliescu M., Corabieru A., Vasilescu D.D

Editorial: WSEAS , WSEAS Press, Computers and Simulation in Modern Science, Volume II, p.75-78, 2008.

Rezumat:

In this paper we present a displacement-frequency sensor including a non-linear resistor with a dynatron-type i(v) dependence, a variable coil and a d.c. voltage source. A general relation is given for the dependence of the period of the oscillations on the coil inductance and on the negative variable resistance of the non-linear resistor respectively. The functioning data of the sensor are presented, for linear and angular displacement respectively. Our sensors could find interesting applications in cardiology.
