Abstract
The utility model discloses a non-contact type displacement sensor, comprising an integration pressure-bearing framework. The outer side of the integration pressure-bearing framework is provided with a coil, and the coil is connected with an external exciting acquisition circuit by a conducting wire. The inner part of the integration pressure-bearing framework is provided with a cavity, and a movable iron core is arranged in the cavity. One end of the iron core is connected with an external mechanical movement part by a connecting piece. The non-contact type displacement sensor has the characteristics of high positioning accuracy, high structural reliability, long using life, simple structure, convenient installation and use, small volume, convenient carrying and transportation, low production cost and easy popularization and use.
Description
Technical field
The utility model belongs to sensor technical field, relates to a kind of displacement transducer, is specifically related to a kind of integrated non-contact type displacement transducer that can work under high temperature, hyperbaric environment.
Background technology
At present, the non-contact type displacement transducer that uses in oil well logging instrument all is high pressure at one end, and other end normal pressure is work down.In order to realize using under this environment, displacement transducer all adopts split-type structural, i.e. sensor and pressure-containing member partial installation used.Split type installation causes the pressure part complex structure, and weld functional reliability under hyperbaric environment is poor, sensor profile diameter problems such as (under the equal electric signal output states) bigger than normal.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, and a kind of non-contact type displacement transducer is provided, its accurate positioning height; The structural reliability height, long service life; Simple in structure, installation, easy to use; Volume is small and exquisite, and transportation is easy to carry; Production cost is low, is convenient to promote the use of.
For achieving the above object, the technical solution adopted in the utility model is: a kind of non-contact type displacement transducer, it is characterized in that: comprise integrated pressure-bearing skeleton, described integrated pressure-bearing skeleton arranged outside has coil, described coil is connected with the external drive Acquisition Circuit by lead, described integrated pressure-bearing skeleton inside is provided with cavity, is provided with movably iron core in the described cavity, and described iron core one end is connected with the exterior mechanical moving component by web member.
Described web member is a steel wire.
Be provided with O-ring seal between described integrated pressure-bearing skeleton and the installation frame.
The utility model compared with prior art has the following advantages:
(1) accurate positioning height.The electromagnetic signal location that this non-contact type displacement transducer adopts coil and iron core to produce, thereby its accurate positioning is very high;
(2) structural reliability height, long service life.The pressure-bearing skeleton of this non-contact type displacement transducer adopts integrated design, thereby its reliable in structure, long service life;
(3) simple in structure, installation, easy to use.This non-contact type displacement sensor structure is simple, installs, uses all very easy;
(4) volume is small and exquisite, and transportation is easy to carry.This non-contact type displacement transducer volume is little, in light weight, is easy to carry very much, transports;
(5) production cost is low, is convenient to promote the use of.The a lot of parts of this non-contact type displacement transducer all are convenient to produce, buy very much, thereby its production cost is very low, is convenient to promote the use of.

Embodiment
A kind of non-contact type displacement transducer as shown in Figure 1, comprise integrated pressure-bearing skeleton 1, described integrated pressure-bearing skeleton 1 arranged outside has coil 2, described coil 2 is connected with external drive Acquisition Circuit 7 by lead, described integrated pressure-bearing skeleton 1 inside is provided with cavity 3, be provided with movably iron core 4 in the described cavity 3, described iron core 4 one ends are connected with exterior mechanical moving component 8 by web member 5.
As shown in Figure 1, described web member 5 is a steel wire.Structure of steel wire intensity is big and diameter in light weight is thin, can not influence measurement result.
As shown in Figure 1, be provided with O-ring seal 6 between described integrated pressure-bearing skeleton 1 and the installation frame.O-ring seal 6 can effectively prevent to install the normal pressure working environment pressure release of the high-pressure work environment on supporter 9 right sides to its left side.
The course of work of the utility model non-contact type displacement transducer is: at first this non-contact type displacement transducer is fixedly mounted on the supporter 9, supporter 9 left sides are atmospheric pressure environment, and supporter 9 right sides are hyperbaric environment.When the exterior mechanical moving component 8 of this non-contact type displacement transducer moves, it moves by the iron core 4 that web member 5 drives in the cavity 3, mobile the making in the coil 2 of iron core 4 produces electric signal, electric signal in the coil 2 is connected with external drive Acquisition Circuit 7 by lead, analyzes the displacement information that obtains exterior mechanical moving component 8 through external drive Acquisition Circuit 7.
The above; it only is preferred embodiment of the present utility model; be not that the utility model is imposed any restrictions; every according to the utility model technical spirit to any simple modification, change and equivalent structure transformation that above embodiment did, all still belong in the protection domain of technical solutions of the utility model.
