Abstract
The utility model discloses a membrane type level indicator. The membrane type level indicator comprises a stainless steel spring plate (1) and a piezoelectric sensor (2), wherein the stainless steel spring plate (1) and the piezoelectric sensor (2) are connected and are simultaneously connected with one end of a casing (4), an electronic circuit board (3) is arranged at the other end of the casing (4), the piezoelectric sensor (2) is connected with the electronic circuit board (3), and an outgoing line (5) is arranged on the electronic circuit board (3). An electronic amplifying loop is arranged on the electronic circuit board (3). The membrane type level indicator is arranged at the bottom of a container for putting materials, an electric signal is output to a display instrument through the variation of the deformation degree of the stainless steel spring plate, and material height can be visually displayed. If the electric signal is output to a controller, required materials can be more conveniently controlled. The device is convenient to install and has a simple structure.
Description
Technical field
The utility model belongs to technical field of electricity, relates to the diaphragm type level-sensing device of the material that a kind of applicable material is heavier, granularity is little.
Background technology
At present, level-sensing device is widely used in industry and life, and its Main Function is that the variation of solid in container (or liquid) height of materials is detected in real time, can be divided into Point Measurement and continuous quantity measure two kinds according to purposes.Wherein comparatively simple for the level-sensing device of Point Measurement, and it is comparatively complicated for continuous quantity, to measure level-sensing device, price is also more expensive.Therefore, design a kind of price relatively cheap, the level-sensing device that can be used on again the occasion of continuous quantity measurement height of materials variation just seems very necessary.
Summary of the invention
The purpose of this utility model is to provide a kind of diaphragm type level-sensing device, for the height of materials position to material is heavier, granularity is little, more liquid, changes measurement is provided continuously.
Technical solutions of the utility model: a kind of diaphragm type level-sensing device, it comprises stainless steel shell fragment and piezoelectric sensor, described stainless steel shell fragment is connected with piezoelectric sensor and both are connected with one end of shell simultaneously, the other end of shell is provided with electronic circuit board, piezoelectric sensor is connected with electronic circuit board, and electronic circuit board is provided with extension line.
Described electronic circuit board is provided with electronics amplifying return circuit.
The utility model is installed on the container bottom of taking advantage of dress material, by the variation of stainless steel shell fragment amplitude of deformation, on the electric signal Displaying Meter of output, just can intuitively show height of materials, if this electric signal is outputed on controller, just can control comparatively easily required material.This device is easy for installation, simple in structure.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment 1 structural representation.
In figure: stainless steel shell fragment 1, piezoelectric sensor 2, electronic circuit board 3, shell 4, extension line 5.
Embodiment
Embodiment 1: comprise stainless steel shell fragment 1 and piezoelectric sensor 2, described stainless steel shell fragment 1 is connected with piezoelectric sensor 2 and both are connected with one end of shell 4 simultaneously, the other end of shell 4 is provided with electronic circuit board 3, piezoelectric sensor 2 is connected with electronic circuit board 3, and electronic circuit board 3 is provided with extension line 5.
Described electronic circuit board 3 is provided with electronics amplifying return circuit.
The utility model technology cardinal principle is: by being installed on the stainless steel shell fragment 1 of the container bottom of taking advantage of dress material, accept the pressure of material and produce distortion, this metamorphosis, in piezoelectric sensor 2, produces electric signal, by electronics amplifying return circuit, this electric signal is exported.Along with the height of materials in container changes, stainless steel shell fragment 1 amplitude of deformation also and then changes, and the electric signal size of output also will change, as long as this electric signal is outputed on Displaying Meter, just can intuitively show height of materials, if this electric signal is outputed on controller, just can control comparatively easily required material.
Claims (2)
