FIELD: measurement technology. SUBSTANCE: bed testing meters of angular velocities includes frame, platform on bed axis, DC motor, collector, two quartz pendulum accelerometers each incorporating quartz plate, capacitive angle transmitter and magnetoelectric moment transmitter connected through proper feedback amplifiers which output stages are manufactured in the form of voltage dividers. Case of first accelerometer is so put on bed platform that its sensitivity axis is perpendicular to radius of platform and case of second accelerometers is so anchored that its sensitivity axis is arranged along radius of platform. Bed also incorporates amplifier of stabilization system with adder included in its mix, photoelectric moire angle transmitter, phase interpolator, unit converting information of photoelectric angle transmitter, processing module incorporating five- channel analog-to-digital converter, two-channel digital-to-analog converter, unified 16- digit interface, processor and computer. EFFECT: increased functional reliability and efficiency. 10 dwgi
