Sensors for measurements of angular velocity and their application in agricultural machines

Abstract

Measurements and control of angular velocity are encountered in many fields of industry, including in agricultural machines. Devices used for measurements of angular velocity are of mechanical or electrical type. The usage of electrical devices which are based on the application of appropriate sensors of angular velocity becomes greater lately. In this paper are given the characteristics of angular velocity sensors which are applied in agricultural machines (optoelectronic, capacitance and electromagnetic sensors and those sensors which are based on Hall's effect) and their specific qualities are pointed out.

Merenje i regulacija ugaone brzine često se sreće u mnogim oblastima industrije, uključujući i poljoprivrednu tehniku. Uređaji za merenje ugaone brzine se dele na mehaničke i električne, pri čemu sve veću primenu imaju električni uređaji zasnovani na primeni odgovarajućih senzora ugaone brzine. U radu su date karakteristike senzora ugaone brzine koji nalaze primenu u poljoprivrednoj tehnici (optoelektronski, kapacitivni, elektromagnetni, senzori na bazi Holovog efekta) i ukazano je na specifičnosti njihove primene u poljoprivrednoj tehnici.
