Abstract
The utility model relates to a liquid level measuring device. As the fluid level transducer in the prior art is unable to take the measurements of deep-etching liquid, the utility model is provided with bellows. One end of each of the bellows is contacted with a sensing unit to completely isolate the deep-etching liquid from the sensing unit, so the device achieves the goal of measuring deep-etching liquid and enlarges the use range of transducers.
Description
The utility model relates to a kind of liquid level emasuring device, particularly a kind of corrosion-resistant fluid level transmitter, and its continuous coverage at a distance especially can be measured corrosive liquids such as strong acid-bases.
Fluid level transmitter of the prior art is owing to be subjected to the restriction of its structure, its sensor directly contacts with fluid to be measured, and most of sensors all adopt metal material to make, so it very easily is corroded, can not measure corrosive liquids such as strong acid, highly basic, can only measure water, oil and some other non-corrosive liquid, so, existing fluid level transmitter usable range is narrow, and practical value is not high.
The purpose of this utility model is to overcome existing above-mentioned deficiency in the prior art, and a kind of corrosion-resistant fluid level transmitter that can measure corrodible liquid is provided.
The purpose that the utility model proposed can realize by following technical solution: also be provided with corrugated tube in fluid level transmitter, this corrugated tube is positioned at the chamber body, and the one end contacts with sensor, and compresses by O-ring seal.
Description of drawings is as follows:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the block scheme of the utility model chip board.
Following the utility model will be in conjunction with the accompanying drawings, and be described in further detail by embodiment:
, Fig. 2 last referring to figure, the utility model comprises cable 1, core cover 2, chip board 3, nut 4, O-ring seal 5, chamber body 6, sensor 7 and corrugated tube 8, cable 1 connects with chip and comes into operation, also can externally use, one end of corrugated tube 8 contacts with sensor 7, be full of neutral liquid in the corrugated tube 8, thereby corrosive liquid and sensor 7 are isolated fully.Chip board 3 is made up of temperature-compensation circuit 10, voltage amplifier circuit 11 and voltage-current converter circuit 12, and this chip board 3 is encapsulated in the cavity I compactly.
During measurement, give the corrugated tube 8 of quality softness by the Hydrostatic Transfer Device of liquid internal, pass to sensor 7 by the neutral liquid in the corrugated tube 8 again, behind the static pressure of sensor 7 liquid bodies, produce voltage signal, temperature compensated circuit 10, voltage amplifier circuit 11 and voltage---current converter circuit 12, measured value is transported in the liquid flow container outside the flow container with the standard electric signal is connected with display instrument or computing machine, in a word, is that the transformational relation by static pressure and liquid level carries out level gauging.
Wherein, corrugated tube 8 can be made with special lemon glue corrosion-resistant, quality softness again.
In addition, also the sensor 7 of replaceable different size comes measure gage pressure, absolute pressure and hydraulic pressure.
The utility model compared with prior art has the following advantages: liquid is quiet not affecting Press when accurately passing to sensor, corrosive liquid and sensor are isolated fully, thereby Can measure the liquid with severe corrosive, enlarge the scope of application, have higher Practical value.
