Embodiment Construction
[0014] The present invention will be further described below in conjunction with accompanying drawing:
[0015] Depend on Figure 1 to Figure 3 As shown, an automatic distillation range liquid level measuring device includes a box body and a measuring cylinder 4 placed in the box body. The box body is composed of a top plate, a bottom plate, a left side plate 9, a right side plate 7, a front plate 10, and a rear plate 8. , wherein the front plate 10 is provided with a transparent window, through which the liquid level in the measuring cylinder 4 and the scale on the measuring cylinder 4 can be clearly seen. An LED light source 2 is fixed on the right side plate 7 of the box, and a lens 5 is fixed inside the LED light source 2 , and the light emitted by the LED light source 2 becomes parallel light after passing through the lens 5 . An emission slit plate 6 is fixed on the inner wall of the right side plate 7, and the emission slit plate 6 is provided with a vertical slit, and...

Disclosed is an automatic distilling range liquid level measuring device. The problems that an existing infrared tube liquid level measuring device is complex in structure, the measured liquid level is not accurate, and faults are likely to appear are mainly solved. The automatic distilling range liquid level measuring device is characterized in that an LED light source (2) is fixedly arranged on a right side plate (7) of a box body, a CIS sensor (1) is fixedly arranged on a left side plate (9) of the box body, and the LED light source (2), a measuring cylinder (4) and the CIS sensor (1) are on the same straight line. The automatic distilling range liquid level measuring device is provided with no mechanical motion components and is simple in structure, low in cost, stable in operation, not likely to break down, and accurate in measuring result.
Description
technical field [0001] The invention relates to the field of chemistry, in particular to an automatic distillation range liquid level measuring device. Background technique [0002] At present, most automatic distillation range meters on the market use infrared to track the liquid level of the tube to measure the recovery volume of the sample after distillation. The current infrared tube liquid level tracking and measuring device is mainly composed of a stepping motor movement mechanism, an infrared receiving reflection probe and a bracket. Run the total number of steps to calculate the volume of liquid in the graduated cylinder. However, the mechanical structure of this measuring device is complicated, and it is difficult to control the movement of the stepping motor and the infrared probe to track the liquid level in the measuring cylinder, which will easily lead to inaccurate measurement of the liquid level, prone to mechanical failure, and high cost.
