摘　　要：差动变压器式位移传感器因其具有结构简单、灵敏度高、线性度好和测量范围宽等优点在工业中被广泛应用,但普通的传感器只适用于常温常压。WY–Ⅱ型存贮式电子流量计专用传感器是在传统差动变压器的基础上,重新设计研制的专门为在深油井下工作的新型传感器,具有耐高温高压、低电压、低功耗的特点。试验结果表明该传感器能在深井的复杂环境中稳定工作。The traditional sensor based on LVDT is applied widely because of its fine performances such as simple structure, high sensitivity, fine linearity and wide measuring rang, etc. But the traditional sensor is merely applied in the measuring environment with normal temperature and pressure. Based on LVDT technology, WY-Ⅱ specific sensor for storable electronic flowmeter is designed specially for working in the deep oil well, which has many advantages such as proof-high-pressure ,proof-high-temperature , low working voltage and low power consumption. The test results show that this kind of sensor is suitable for working stably in the complicated surroundings.
