Specific embodiment
Accompanying drawing is combined especially by preferred embodiment below to be described in further detail this utility model.
With reference to Fig. 1, a kind of corrosive liquids liquid level emasuring device developed based on secondary meter, including rocking handle 1, little bearing
Seat 2, circuit control box 3, displacement transducer 4, guide pillar 5, base 6, bearing plate 7, Fibre Optical Sensor 8, elevator 9, trapezoidal spiral shell
Bar 10, linear bearing seat 11, bevel gear are to 12；The rocking handle 1 passes through key and bevel gear and coordinates to 12, and the bevel gear changes to 12
After having become the direction of motion, it is connected with the upper end of trapezoidal screw 10 by key, the lower end of the trapezoidal screw 10 passes through bearing plate 7
It is connected with base 6, the trapezoidal screw 10 is connected by feed screw nut with elevator 9, forms screw pair, the elevator
9 front end is provided with Fibre Optical Sensor 8, and two guide pillars 5 are fixed on the both sides of trapezoidal screw 10, and two linear bearing seats 11 are distinguished
With two 5 shaft hole matchings of guide pillar, 9 both sides of the elevator are also shaft hole matching with two linear bearing seats 11, the circuit control
Case processed 3 is arranged on the left of device, mainly includes displacement transducer 4, digital display secondary meter.
Cleaning Principle of the present utility model such as Fig. 2, measurement sensor are placed in ullage, and the test desk for moving up and down ensures
Sensor obtains suitable optical signal.Due to being corrosive liquids level gauging, sensor uses acid-proof material.
With reference to Fig. 3, Fig. 4, in this utility model, the emphasis for not being both detection of the height of liquid level, even the liquid of very little
The change of position height is also required to measure.For the requirement of basic accuracy, digital display device is necessary.Measurement head is apart from liquid level
The intensity of the different light for receiving of height be different, so as to be the different signals of telecommunication the high-degree of conversion apart from liquid level,
The signal of telecommunication carry out appropriate finishing, filtering, amplification be transferred to secondary meter.Due to it is desirable that the concrete numerical value of height, therefore need
Appropriate exploitation is carried out to secondary meter, the concrete numerical value that the signal of telecommunication of input is converted into height is displayed in user interface
On.The signal that fiber sensor measuring goes out has very big signal noise and signal has certain fluctuation to be unfavorable for the defeated of secondary meter
Enter to quantify, the process to signal is very important.The disturbance of the air around liquid level and the change of temperature are to systematic error
Impact be also detrimental to measure.The method that error concealment twice need to be adopted, is the filter and amplification finishing in signal for the first time
Where reduce signal fluctuation and abate the noise.It is using intelligentized secondary instrument for the second time after signal enters secondary meter
Table.Frequency translation is to be measured by the demarcation that can measure recycling sensor after intellectuality to frequency.Ambient temperature pair
The impact of certainty of measurement obtains amendment automatically and ensure that good service precision and data reliability.
With reference to Fig. 5, in this utility model, this device control circuit is broadly divided into three parts, and Fibre Optical Sensor, displacement are passed
Sensor, digital display secondary meter.Optical fiber measurement head is formed by the electric eye transformation of the way in accumulator, can be by the distance apart from liquid level
Change causes the difference of the light levels of light, and optical signal is converted into the signal of telecommunication, opto-electronic conversion is carried out.Displacement transducer is main
It is the WYH slider displacement sensors using the new quick electronics in Xi'an, aluminium shell does anodic electrophoresis process, and corrosion resistance is strong, will rise
The displacement of drop platform is converted into voltage signal and is shown by digital display.
The corrosive liquid level detecting apparatus, it is possible to achieve the measurement to corrosive liquids liquid level, ensure that precision, and energy
Error is reduced based on intelligent secondary instrument, by bevel gear screw-nut body, simple structure, collocation guide pillar fully can be protected
