Abstract研制了一种检测渗透到金属设备中的原子氢浓度的探测仪,该探测仪的渗氢电流测量范围为0~400~4000μA.在40OμA,仪器自动切换量程.在400μA以下的量程段,仪器的分辨力为0.1μA.渗氢电流信号的测量精度为±1%.传感器的背景电流。
Other AbstractA probe for detecting the concentration of atomic hydrogen permeated into the wall of metallic e-quipment has been developed. The measuring range of the probe is 0-400-4 000μA. The probe changes its scales automatically at 400*A. Below 400μA, the resolution of the probe is 0.1μA. The measuring accuracy of current signal is ±1%. The base current density is less than 0. 6μA · cm-2. The amplitude of current signal will not attenuate if the probe is placed in the central control room within 400m from the sensor.
