Description
Technical field
The utility model relates to a kind of automatic measurement Displaying Meter, and particularly a kind of coil of wire that is used to detect the liquid level that shows internal tank shows the high-precision liquid level meter.
Background technology
The product structure that is used at present to detect the liquid level that shows internal tank both at home and abroad all adopts disc spring and the weight structure situation as rotational power.This disc spring dynamic structure to be adopted and the non-coaxial connected mode fully of metering drum, and complex structure is not easy to make, whole assembling weak effect.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of coil of wire simple in structure, that precision is high to show the high-precision liquid level meter.
The technical scheme that the utility model gets rid of employing is: a kind of coil of wire shows the high-precision liquid level meter, by outer catheter, be placed in the magnetic float of outer catheter periphery, be positioned at outer catheter and the magnet steel corresponding with magnetic float, the instrument housing that links to each other with an end of outer catheter, be positioned at the support of instrument housing, the coaxial panel board that is fixed on the support, pointer, gear set, high precision multiturn potentiometer and current converter constitute, in instrument housing, also be provided with and potentiometer and the coaxial metering drum spring assembly of pointer, be positioned at the lower end of metering drum spring assembly and be fixed in steel wire automatic winding displacement guide wheel on the support, also be provided with and be positioned at outer catheter, one end is connected with interior magnet steel, the stainless steel wire that the other end is connected with metering drum spring assembly.
The utlity model has simple in structure, stable performance, the reliability height, the precision height, long service life, practicality is good, not influenced by the top shake, does not need field adjustable, on-the-spotly shows eye-catching characteristics.And can realize exporting automatically the DC4-20mA standard signal.Applied widely, can be used for the level gauge of industries such as oil, chemical industry, light industry, system water supply, liquefied gas.

Embodiment
As Fig. 1, Fig. 2, shown in Figure 3, coil of wire shows the high-precision liquid level meter, by outer catheter 1, be placed in the magnetic float 2 of outer catheter 1 periphery, be positioned at outer catheter 1 and the magnet steel 4 corresponding with magnetic float 2, the instrument housing 7 that links to each other with an end of outer catheter 1, be positioned at the support 14 of instrument housing 7, the coaxial panel board 8 that is fixed on the support 14, big pointer 9, little finger of toe pin 11, gear set 10, high precision multiturn potentiometer 12 and current converter 13 constitute, in instrument housing 7, also be provided with and potentiometer 12 and big or small pointer 9,11 coaxial metering drum spring assemblies 6, be positioned at the lower end of metering drum spring assembly 6 and be fixed in steel wire automatic winding displacement guide wheel 5 on the support 14, also be provided with and be positioned at outer catheter 1, one end is connected with interior magnet steel 4, the stainless steel wire 3 that the other end is connected with metering drum spring assembly 6.
Wherein measure the principle of drum spring assembly 6 employing box chis.Because metering drum 6 direct and big pointer 9 coaxial rotations, when liquid level raises, because float 2 moves up and down with liquid level, positive and negative rotation corresponding actions takes place in drum 6, float 2 downwards the time because of magnet in the float 2 and interior magnet steel 4 couplings in the outer catheter 1, make metering drum 6 drive big pointer 9 the inhour running takes place, this moment, disc spring was in the state of screwing; When float 2 made progress, metering drum 6 rotated because of the positive hour hands of disc spring twisting force with big pointer 9, and then the realization automatic gauge shows the liquid level height.
Concrete enforcement is, the outer catheter 1 that will install magnetic float 2 at the flow container top is packed in the flow container, instrument shows that housing 7 links into an integrated entity by flange and tank body, and float 2 rises with liquid level or decline causes measuring drum 6 and pointer 9 corresponding rotations realize showing automatically liquid level purpose just.When the needs teletransmission, can be by exporting the DC4-20mA standard signal with the high precision multiturn potentiometer 12 of metering drum 6 coaxial rotation and the current conversion of current converter 13.
Liquid level gauge also links to each other with photoelectric encoder, directly exports digital pulse signal by scrambler, realizes digit pulse output and finishes the teletransmission high-acruracy survey.
