Abstract
FIELD: instruments, in particular, security and fire emergency devices, devices which measure linear size. SUBSTANCE: device has reference voltage generator which outputs rectangular pulses which on-off rate is equal to 2 and which has two opposite-phase outputs, capacitance detector, second capacitance detector or tuned capacitor, adder and recording unit, which has linear amplifier and phase-sensitive detector. EFFECT: increased efficiency, increased precision.
