Abstract
The utility model relates to a liquid level detection device for a biological chip sampler. The liquid level detection device for the biological chip sampler is characterized by comprising a base, wherein at least one tray for accommodating clean water storage bottles or sewage storage bottles is moveably sleeved into the base; a weighing sensor is arranged between the bottom of the tray and the base; and the weighing sensor is connected with a control system. The liquid level detection device for the biological chip sampler has a simple and compact structure, is convenient to use, adopts a non-contact liquid level detection method, has high detection precision, avoids pollution to the liquid and has long service life.
Description
Technical field
The utility model relates to a kind of biochip point sample instrument, especially relates to a kind of biochip point sample instrument and uses liquid level detection device.
Background technology
In the prior art, the clear water liquid storage bottle of biochip point sample instrument or the automatic liquid level detection system of sewage liquid storage bottle mostly detect liquid level through the way of contact, and there is following problem in it:
1, the direct contact liq of contact Level Detection very easily constitutes liquid and pollutes.
2, the contact Level Detection is subject to the influence of liquid fluctuating, and accuracy of detection is not high.
3, owing to want long period of soaking in liquid, liquid body corrodes or corrosion, and the contact detecting sensor not only influences accuracy of detection, and serviceable life is shorter.
The utility model content
The applicant has carried out studying and improved to above-mentioned problem, provides a kind of biochip point sample instrument to use liquid level detection device, and is simple and compact for structure, adopts the non-contact detecting mode, and accuracy of detection is high, avoid liquid is constituted pollution, and long service life.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of biochip point sample instrument is used liquid level detection device; Comprise pedestal; At least one pallet movable set that is used for placing clear water liquid storage bottle or sewage liquid storage bottle is provided with LOAD CELLS between the bottom of pallet and the pedestal, the LOAD CELLS connection control system at pedestal.
Further:
Said LOAD CELLS is a resistance strain weighing transducer.
The technique effect of the utility model is:
The disclosed a kind of biochip point sample instrument of the utility model is used liquid level detection device, and is simple and compact for structure, easy to use, adopts contactless Level Detection mode, and accuracy of detection is high, avoid liquid is constituted pollution, and long service life.
Description of drawings
Fig. 1 is the three-dimensional structure synoptic diagram of the utility model.
Fig. 2 is the front view of the utility model.
Fig. 3 is the control system logical diagram of the utility model.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done further detailed explanation.
Like Fig. 1, shown in 2; The utility model comprises pedestal 1; Two pallet 2 movable sets are in pedestal 1, and pallet 2 is used to place clear water liquid storage bottle or sewage liquid storage bottle 4, are provided with LOAD CELLS 3 between the bottom of pallet 2 and the pedestal 1; LOAD CELLS 3 connection control system, LOAD CELLS 3 is a resistance strain weighing transducer.The complete automatic liquid level detection system of a cover as shown in Figure 3, that control system is made up of signal amplification circuit, A/D change-over circuit, CPU and Control Software and alarm lamp.Clear water liquid storage bottle and sewage liquid storage bottle are placed on respectively on the pallet 2 during use; Water in the clear water liquid storage bottle is supplied with ultrasonic tank and rinse bath use through peristaltic pump; Or flow into waste water in the sewage liquid storage bottle from ultrasonic tank and rinse bath, when the water of clear water liquid storage bottle is lower than the value of setting or value that the water in the sewage liquid storage bottle is higher than setting is just reported to the police automatically.Control system is mainly amplified the faint voltage signal of LOAD CELLS 3 outputs; When the weight of liquid increased gradually, the increase that the output voltage of LOAD CELLS 3 can be was gradually amplified through amplifying circuit then; The last pin that is input to CPU again carries out the AD sampling; Software converts voltage signal into weight, and then weight is converted into the liquid level of liquid, and then judges the height of liquid level in the container; The output signal is reported to the police when transfiniting, thereby realizes contactless liquid level control.
