本文叙述的Paraloc~R“振荡器是一种相移型振荡器,其振荡频率受传感器桥路的输出电压与输入电压之比的控制。用振荡器的输出激励传感器网络和正交网络,并将这两个网络的输出之和加到振荡器的输入端。可以做到在振荡器很稳定工作时,”误差“信号改变±1/2%,产生的频偏是±33%。振荡器的这种特性使它能适用于各种类型的传感器和传感器网络,以实现对各种物理量的高精度测量,因而也就使它特别适用于海洋学测量。
Paraloc ~ R ”oscillator described in this paper is a kind of phase shift type oscillator whose oscillation frequency is controlled by the output voltage and input voltage ratio of the sensor bridge.The output of the oscillator is used to excite the sensor network and the orthogonal network, And adds the sum of the outputs of these two networks to the input of the oscillator. It can be achieved that the “error” signal changes by ± 1/2% and the resulting frequency deviation is ± 33% when the oscillator is very stable This feature of the oscillator makes it suitable for all types of sensors and sensor networks to achieve high-precision measurements of various physical quantities, thus making it particularly suitable for oceanographic measurements.
