Abstract
The invention discloses a differential transformation type displacement sensor. The sensor comprises a measuring rod (1), a probe housing (2), a probe wire (3), a signal amplifier (4), and a power supply output terminal (5), wherein the measuring rod (1), the probe housing (2), the probe wire (3), the signal amplifier (4), and the power supply output terminal (5) are connected orderly from left to right. A primary coil (22) is arranged at one side of the probe housing (2) and two secondary coils (23) are arranged at the other side of the probe housing (2); and an iron core (21) is arranged in a cavity that is enclosed by the primary coil (22) and the two secondary coils (23). According to the invention, the sensor has advantages of small volume and light weight; moreover, an electrical signal is enhanced and the measuring precision is high; and thus the sensor can be applied to work on long-distance and adverse conditions.
Description
Technical field
The present invention relates to fields of measurement, especially relate to a kind of differential pressure swing type displacement transducer.
Background technology
Displacement transducer is widely used in the Displacement Measurement engineering of many industries, as: industries such as textile industry, light industry, metallurgy, differential pressure swing type displacement transducer converts electric signal output to by the mechanical-physical amount, and the conversion of signals of output is become unipolarity or bipolarity.Present displacement transducer, though can Displacement Measurement because its inner structure complexity, so volume is big, weight is big, and since the signal of output a little less than, and can't realize remote measurement.
Summary of the invention
The present invention is that present volume is big, weight is big in order to solve, the problem a little less than the signal, a kind of differential pressure swing type displacement transducer has been proposed for this reason, comprise measuring staff 1, probing shell 2, probe wire 3, signal amplifier 4 and power output end 5, connect successively from left to right, a side is provided with primary coil 22 in the described probing shell 2, opposite side is provided with two secondary coils 23, is provided with an iron core 21 in the cavity that described primary coil 22 and two secondary coils 23 surround.
Differential pressure swing type displacement transducer of the present invention, described iron core 21 is connected with measuring staff 1.
