Description

A kind of throwing static pressure liquid level transmitter calibration equipment
Technical field
The utility model relates to the check meter professional skill field, relates in particular to a kind of throwing static pressure liquid level transmitter calibration equipment.
Background technology
For a long time, the verification throwing static pressure liquid level transmitter is all adopt the verification pond of large-scale specialty and electronicly carry out the throwing static pressure liquid level transmitter verification to row's equipment, but have the ⑴ time and effort consuming: because the verification throwing static pressure liquid level transmitter needs mock standard verification pond, whole checking procedure needs constantly that the liquid level in simulation change standard verification pond reaches the verification purpose; ⑵ input cost is higher: need to start feed pump and unwatering pump water consumption consuming time when the liquid level in simulation change standard verification pond; ⑶ labour intensity is large: in verification throwing static pressure liquid level transmitter process, need many people to coordinate repeatedly to settle the standard the scale, energy undue concentration of the liquid level in verification pond and cause tired aggravation; ⑷ testing accuracy is low: observe sight line and stochastic error easily occurs, can not guarantee accurate check; ⑸ whole calibration equipment needs specific factory building, for the verification throwing static pressure liquid level transmitter, certain limitation is arranged.
Therefore, how to solve in verification throwing static pressure liquid level transmitter process Static and dynamic factor defective, particularly input cost particularly outstanding.Moreover, perplexing the operator from factors such as checking precision, labour intensity, work efficiency, operating environment and fitness always.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of throwing static pressure liquid level transmitter calibration equipment that reduces input cost and labour intensity, increases work efficiency.
For addressing the above problem, a kind of throwing static pressure liquid level transmitter calibration equipment described in the utility model comprises throw-in type fluid level transmitter detecting head and intelligent standard pressure testers, and it is characterized in that: this device also comprises linker; Be respectively equipped with standard scale web member, web member I, web member II on described linker, the one end is provided with the mouth of exerting pressure that is connected with the handball emulsion tube of exerting pressure; Described throw-in type fluid level transmitter detecting head is by the described web member I described linker of packing into; Described intelligent standard pressure testers is connected with described standard scale web member; Described web member II is provided with plug wire; The measuring junction that the direct current 24V output interface of described intelligent standard pressure testers, CD output interface access respectively described throw-in type fluid level transmitter.
Described web member I is provided with sealant tape.
The utility model compared with prior art has the following advantages:
1, due to the mouth of exerting pressure that is provided with linker in the utility model and is connected with the handball emulsion tube of exerting pressure, therefore, utilize the static pressure measurement principle in time to carry out the verification correction to the throw-in type fluid level transmitter of long-term use, not only improved work efficiency, and guarantee the measurement of throw-in type fluid level transmitter accurately, thereby it is difficult effectively to have filled up the verification of throw-in type fluid level transmitter, coarse defective.
2, the utility model is simple in structure, and is with low cost, time saving and energy saving, can be to dissimilar throwing static pressure liquid level transmitter verification, and people's complete independently is easy and simple to handle, and elementary above operative skill person can operate, and has greatly reduced input cost.
Description of drawings
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
In figure: 1-standard scale web member, 2-web member I, 3-web member II, 4-linker, the 5-mouth of exerting pressure.
Embodiment
As shown in Figure 1, a kind of throwing static pressure liquid level transmitter calibration equipment comprises throw-in type fluid level transmitter detecting head, intelligent standard pressure testers, linker 4.Be respectively equipped with standard scale web member 1, web member I 2, web member II 3 on linker 4, the one end is provided with the mouth 5 of exerting pressure that is connected with the handball emulsion tube of exerting pressure; Throw-in type fluid level transmitter detecting head is by web member I 2 linker 4 of packing into; The intelligent standard pressure testers is connected with standard scale web member 1; Web member II 3 is provided with plug wire, can be respectively to the verification of different throw-in type fluid level transmitter detecting head; The measuring junction that the direct current 24V output interface of intelligent standard pressure testers, CD output interface access respectively the throw-in type fluid level transmitter, red line connects positive pole; The black line connects negative pole.
Wherein: web member I 2 is provided with sealant tape.
During use, open the intelligent standard pressure testers, set output 24V CD, adjust corresponding pressure unit and calibration current and test, the standard figures verification is read in the handball pressurization with exerting pressure.
Utilize the static pressure measurement principle, when the throw-in type fluid level transmitter was put in fluid to be measured a certain degree of depth, the sensor on detecting head was met the pressure formula that liquid level is subject to and is: Ρ=ρ * g * H+Po.In formula: the P---transmitter is met the liquid level pressure, ρ---fluid to be measured density, and the g---local gravitational acceleration, atmospheric pressure on the Po---liquid level, the H---transmitter drops into the degree of depth of liquid.
Because the atmospheric pressure Po on liquid level is connected with the negative pressure cavity of sensor, with the Po at the offset sensor back side, make sensor record pressure to be: ρ * g * H.So by measuring pressure P, can obtain the liquid level degree of depth.
