KSGYR311M Triaxial Universal Angular Rate Gyro
Product Introduction
KSGYR311M series three-axis universal angular rate gyro is
developed by Kacise, which is used to measure the three-axis
angular rate sensor. Each of the three axis angular rate gyro uses
MEMS technology chip, with high performance, low cost, high
reliability and high package ruggedness, and has Self-Test
function.
Operating principle:
KSGYR311M series three-axis universal angular rate gyro works
according to the principle of resonator gyro. Two polysilicon
sensitive structures, each containing a high-frequency vibrating
frame, which is driven electrostatically and resonates, form the
necessary speed elements. The two outer ends of the frame form a
capacitance-sensitive structure that is sensitive to the Coriolis
motion generated at the angular rate and generates an electrical
signal, which is transmitted to the amplifying stage and the
modulating stage, thus output an electrical signal proportional to
the angular rate.
