The possibility of constructing a horizontal type fiber-optic accelerometer based on a multi-turn sensing element, an optical scheme of the Mach-Zender interferometer and passive phase demodulation is shown. Laboratory tests of the accelerometer prototype were carried out. The sensitivity of the presented fiber-optic accelerometer is 1770 rad/g. Keywords: accelerometer, interferometer, optical fiber.
