High sensitivity measurement device for measuring various parameters of non-electric quantity |
摘要 |
A sensing element is constituted by a single or plurality of p-n junctions alternating between the foward and reverse states. A pulse circuit applies different magnitudes of foward and reverse currents to the sensing element. A high reverse current is applied for a self heating interval and a small foward current is applied for a sensing interval.
