Description
Technical field
The present invention relates to displacement sensors, and in particular to the oil pressure displacement module of hydraulic type displacement sensor.
Background technique
Displacement sensor is also known as linear transducer, is a kind of linear unit for belonging to metal induction, the effect of sensor
It is that various measurands are converted to electricity.In process of production, the measurement of displacement is generally divided into measurement full size and machine
Tool is displaced two kinds.Form by measured variable transformation is different, and displacement sensor can be divided into analog and two kinds digital.It is analog
Physical property type and two kinds of structural type can be divided into again.Common displacement sensor is in the majority with analog structure type, including potentiometric displacement
Sensor, inductive displacement transducer, selsyn, capacitive displacement transducer, electric vortex type displacement sensor, Hall-type position
Displacement sensor etc..One important advantage of digital displacement transducer is easy for signal being sent directly into computer system.
Displacement is amount related with the movement of the position of object during the motion, model involved in the measurement method of displacement
It is quite extensive for enclosing.Thin tail sheep is usually examined with strain-type, inductance type, differential transformer type, eddy current type, Hall sensor
It surveys, big displacement commonly uses the sensing technologies such as inductosyn, grating, capacitive grating, magnetic grid to measure.Wherein grating sensor is because having
Easily realize that digitlization, precision high (resolution ratio is highest at present can reach nanoscale), strong antijamming capability, no artificially reading miss
It is poor, easy for installation, using it is reliable the advantages that, obtain increasingly extensive application in machine tooling, the detection industries such as instrument.
Especially in the field of construction, due to the place narrow in a few thing environment, common potentiometric displacement sensing
Device, Hall displacement transducer are larger in equal volume, are not easy to measure, so a displacement small in size, easy to detect is needed to pass
Sensor.
Summary of the invention
The defect and deficiency of the prior art of being solved of the invention provide the oil pressure displacement mould of hydraulic type displacement sensor
Block improves measurement applicability, is convenient for measuring narrow environment.
The present invention is achieved through the following technical solutions：
The oil pressure displacement module of hydraulic type displacement sensor, including oil compression rod, oil pressure pipe, the oil inlet of the oil compression rod are close
One end of envelope connection oil pressure pipe, and the telescopic end of the oil compression rod is connected with slide rheostat, the telescopic end of the oil compression rod is flexible
When, the resistance value of the slide rheostat also changes correspondingly；The other end of the oil pressure pipe is connected with backpressure pump, and the backpressure pump is used for
The oil compression rod and oil pressure pipe are provided hydraulic.
Further, the oil pressure displacement module of the hydraulic type displacement sensor, further includes single-chip microcontroller, the single-chip microcontroller
For detecting the resistance value of slide rheostat.
Further, the oil pressure displacement module of the hydraulic type displacement sensor, further includes motor driver, the motor
Driver is connect with single-chip microcontroller, and the motor driver is for driving backpressure pump.
Compared with prior art, the present invention having the following advantages and benefits：
The oil pressure displacement module structure of hydraulic type displacement sensor of the present invention is simple, and operation is simple, for measurement acquisition displacement
Data are provided convenience, and durable, long service life.
Detailed description of the invention
Attached drawing described herein is used to provide to further understand the embodiment of the present invention, constitutes one of the application
Point, do not constitute the restriction to the embodiment of the present invention.In the accompanying drawings：
Fig. 1 is schematic structural view of the invention.
Specific embodiment
