Abstract
The utility model provides an array type platinum resistance liquid-level measurement device, which comprises an array, a measurement circuit and a data terminal, wherein the array is composed of a plurality of platinum resistors; the measurement circuit is used for measuring the resistance value of each platinum resistor on the array; the data terminal is used for acquiring measurement data and judging the liquid-level height. According to the utility model, the liquid-level measurement device without a mechanical structure is established; the measurement temperature area is wide; a measurement result is visualized and reliable; the liquid-level height of liquid at normal temperature or low temperature is convenient to measure.
Description
Technical field
The utility model relates to a kind of for measuring the device of liquid level position.
Background technology
The measurement of liquid level is widely used technology in commercial production, daily life and scientific research.Present widely used liquid level sensor is of a great variety, such as differential pressure type level gauge, liquid level feeler lever, capacitance level gauge, ultrasonic level gage, radar level gauge, float level meter etc.These liquid level gauges based on principle different, but the method for dealing with various requirements is few comprehensively.Particularly, when measuring super-low liquid liquid level, due to the physical characteristics of ultralow temperature, applicable liquid level gauge is considerably less.Such as the liquid level gauge by mechanical buoyancy judgement liquid level, under low temperature environment, there will be because of getting stuck that freeze, material volume variation etc. causes.And the hts band liquid level gauge that utilizes superconduction principle design is measured accurately, but expensive, limit its widespread use.
Summary of the invention
The utility model provide a kind of based on array platinum resistance applicable to the extensive liquid surface measuring device of warm area.
The utility model is by the following technical solutions:
Array platinum resistance liquid surface measuring device, is characterized in that: comprise that many platinum resistance form array, measure the metering circuit of each platinum resistance resistance value on array and gather measurement data and differentiate the data terminal of liquid level.
During measurement, many platinum resistance are formed to array immersed in liquid level, and after energising, platinum resistance starts heating, because the coefficient of heat transfer of liquids and gases is inconsistent, cause on liquid level and liquid in the temperature of platinum resistance inconsistent, inconsistent its resistance value that causes of temperature of platinum resistance is variant.By metering circuit, measure the resistance value of each platinum resistance on array, by data transfer, to data terminal, data terminal determines liquid level position according to resistance value difference size.
As to the improving and supplementing of technique scheme, the utility model further adopts following technical measures or the combination in any of these measures.
Described many platinum resistance form array, and the length of this array can require to determine according to concrete measurement.
Described many platinum resistance form array, and integrated platinum resistance number of elements and position can require to determine according to measuring accuracy.
Described collection measurement data is also differentiated the data terminal of liquid level, can adopt display screen feedback data.
Described collection measurement data is also differentiated the data terminal of liquid level, can send data to other data terminals.
Beneficial effect: the utility model is set up the liquid surface measuring device of a machinery-free structure according to the physical characteristics of platinum resistance, measures warm area extensive, and intuitive measurement results is reliable, is convenient to measure the liquid level of normal temperature or cryogenic liquid.
Accompanying drawing explanation
Fig. 1 is apparatus structure schematic diagram of the present utility model.
In the drawings: 1, many platinum resistance form array; 2, measure the metering circuit of each platinum resistance resistance value on array; 3, gather measurement data and differentiate the data terminal of liquid level.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, array platinum resistance liquid surface measuring device of the present utility model, comprises that many platinum resistance form arrays 1, measures the metering circuit 2 of each platinum resistance resistance value on array, gathers measurement data and differentiates the data terminal 3 of liquid level.
During work, many platinum resistance are pressed to differing heights and with common ground method, form array, each platinum resistance all has wire to be connected in metering circuit.This array is put into testing liquid, powers up rear platinum resistance and start heating, because the coefficient of heat transfer of liquids and gases is inconsistent, cause on liquid level and liquid in the temperature of platinum resistance inconsistent, inconsistent its resistance value that causes of temperature of platinum resistance is variant.Metering circuit is measured the resistance value of each platinum resistance and resistance value is transferred to data terminal, and data terminal is analyzed data, goes out each resistance value medium of living in, thereby indirectly obtain liquid level according to resistance value diversity judgement.These liquid level data can show by display screen mode, or data are passed to other data terminals composition automatically working systems.
Embodiment recited above is described preferred implementation of the present utility model; not scope of the present utility model is limited; design under spiritual prerequisite not departing from the utility model; various distortion and improvement that the common engineering technical personnel in this area make technical solutions of the utility model, all should fall in the definite protection domain of claim of the present utility model.
