光纤高频信号发生器(简称发讯器)是合肥仪表总厂委托我室研制的,它与双转子流量计配套使用,主要用于石油工业等方面。发讯器的脉冲数与流量计的排量成正比,其分辨率使流量计有很高的精度,并具防爆性能,还可测速、测角等。 发讯器的工作原理如下:一个带有二列明暗条纹的圆刻度片装在发生器的转轴上,当流量计带动转轴转动时,刻度片条纹遮断光源,使得二组编排的光纤分别采样,经信号处理后输出电脉冲,单脉冲是旋转一周产生一个信号,多脉冲则为250个脉冲/
Optical fiber high-frequency signal generator (referred to as the sender) Hefei Instrument Factory commissioned by my room developed, it is supporting the use of dual-rotor flowmeter, mainly for the oil industry and so on. The number of transmitters is proportional to the flow rate of the flowmeter. The resolution of the flowmeter provides a high degree of accuracy and explosion-proof performance, as well as speed and angle measurement. The working principle of the transmitter is as follows: A circular scale with two lines of light and dark stripes is mounted on the shaft of the generator. When the flowmeter drives the shaft to rotate, the stripes of the grating block the light so that the two groups of optical fibers are sampled respectively, After the signal processing output electric pulse, single pulse is a rotation of a week to produce a signal, multi-pulse is 250 pulses /
