The sensor feeler lever is installed on the electronic bin and sleeved with the floater, and the sensor feeler lever and the floater are located in the outer tube. According to the portable liquid level sensor, the sensor feeler lever and the floater are sleeved with the outer tube, the damage proofing performance is improved, the portable liquid level sensor can be conveniently carried and stored, and the anti-fluctuation characteristic is achieved.
Description
Technical field
The utility model relates to sensor technology, relates to a kind of portable liquid level sensor.
Background technology
In the fields of measurement of liquid level sensor, magneto strictive sensor is the generally acknowledged liquid level sensor that reliability is high, precision is high.As shown in Figure 1, the magneto strictive sensor of prior art comprises electronics storehouse 101 and sensor feeler lever 201, on described sensor feeler lever, is provided with float 301.Wherein, it is stainless steel sensor feeler lever more than 12mm that described sensor feeler lever 201 adopts external diameter, and adopt of the external diameter of float 301 is greater than 60mm more.
Although the ratio of precision of this class sensor is higher, be all only applicable to use under fixed installation mode.If sensors with auxiliary electrode were need to be used under frequent dismounting, the environment moved, be prone to the uncomfortable factors such as inconvenience, feeler lever is crooked, float breaks of carrying.In addition, because float physical dimension greatly also can affect the accuracy of actual measurement.
Thereby prior art need to improve.
Summary of the invention
In view of above-mentioned the deficiencies in the prior art part, the purpose of this utility model is to provide a kind of portable liquid level sensor, and while using under frequent dismounting, the environment moved to solve existing liquid level sensor, fragile sensor, affects the problem of accurate testing degree.
In order to achieve the above object, the utility model has been taked following technical scheme:
A portable liquid level sensor, comprises electronics storehouse, sensor feeler lever and float, and described sensor feeler lever is connected with described electronics storehouse, and described float is sheathed on described sensor feeler lever, and it also comprises outer tube, and described sensor feeler lever and float are arranged in outer tube.
In described portable liquid level sensor, described electronics is provided with horizontal indicating mechanism on storehouse.
In described portable liquid level sensor, in the upper end of described sensor feeler lever, be provided with horizontal indicating mechanism.
In described portable liquid level sensor, on described outer tube, be provided with scale label.
In described portable liquid level sensor, the external diameter of described sensor feeler lever is 6mm.
In described portable liquid level sensor, the external diameter of described float is less than 30mm, internal diameter is less than 10mm.
In described portable liquid level sensor, the external diameter of described float is that 20mm, internal diameter are 8mm.
Compared to prior art, the portable liquid level sensor that the utility model provides, by be arranged with the outer tube of anti-damage defencive function at sensor feeler lever and float, has increased anti-damage performance.Also there is anti-fluctuation function, also make it easy to carry and store simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of the liquid level sensor of prior art.
Fig. 2 is the structural representation of the utility model portable liquid level sensor.
Embodiment
The utility model provides a kind of portable liquid level sensor, for making the purpose of this utility model, technical scheme and effect clearer, clear and definite, referring to the accompanying drawing embodiment that develops simultaneously, the utility model is further described.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 2, it is the structural representation of the utility model portable liquid level sensor.As shown in Figure 2, portable liquid level sensor of the present utility model comprises electronics storehouse 10, sensor feeler lever 20, float 30 and outer tube 40, described sensor feeler lever 20 is connected with described electronics storehouse 10, described float 30 is sheathed on sensor feeler lever 20, described outer tube 40 can be installed on described electronics storehouse 10, and described sensor feeler lever 20 and float 30 are arranged in outer tube 40.
In the present embodiment, described outer tube 40 is for having the outer tube of anti-damage defencive function.Described sensor feeler lever 20 can directly be electrically connected to electronics storehouse 10, also can be connected with electronics storehouse 10 by electric wire.Described sensor feeler lever 20 is titanium alloy sensor feeler lever, and described outer tube 40 is the anti-fluctuation outer tube of titanium alloy.Because titanium alloy material is higher than traditional stainless steel light weight, intensity, good toughness, be easy to carry.
In order to improve reaction sensitivity and the measuring accuracy of portable liquid level sensor, in the present embodiment, the external diameter of described sensor feeler lever 20 is preferably 6mm.
Further, the external diameter of described float 30 is less than 30mm, internal diameter is less than 10mm.In the present embodiment, the external diameter of described float 30 is that 20mm, internal diameter are 8mm, more accurate, sensitive when float 30 is fluctuated, and makes metering more accurate.
The utility model is by using less, lighter sensor feeler lever 20, and the less float 30 of use, makes the reaction of portable liquid level sensor of the present utility model sensitiveer, more accurate, and is easy to carry.
Please continue to refer to Fig. 2, in portable liquid level sensor of the present utility model, on described electronics storehouse 10, be provided with horizontal indicating mechanism 50, during concrete enforcement, described outer tube 40 is installed on the bottom surface in electronics storehouse 10, and horizontal indicating mechanism 50 is installed on the end face in electronics storehouse 10, and this horizontal indicating mechanism 50 can adopt horizontal checkout instrument, be convenient to portable liquid level sensor and control in the verticality of testing process, further improve actual measurement accuracy.In other embodiments, described horizontal indicating mechanism 50 also can be installed in other position of portable liquid level sensor, as horizontal indicating mechanism 50 being installed in to the upper end of sensor feeler lever 20, as long as horizontality that can indicator solution level sensor when measuring.
Further, on described outer tube 40, can be provided with scale label (not shown), make portable liquid level sensor of the present utility model can be used for manual dipping, further increase the function of portable liquid level sensor.
In sum, the portable liquid level sensor that the utility model provides, by the outer tube with anti-damage defencive function is set on electronics storehouse, has increased anti-damage performance, and easy to carry and store also have an anti-wave energy.In addition, owing to adopting smaller sensor feeler lever and the float of external diameter, improved reaction sensitivity and the accuracy of portable liquid level sensor.And on electronics storehouse, (or feeler lever upper end) arranges horizontal indicating mechanism and is convenient to verticality in testing process and controls, and further improved measuring accuracy.
Be understandable that; for those of ordinary skills; can be equal to replacement or change according to the technical solution of the utility model and utility model design thereof, and all these changes or replacement all should belong to the protection domain of the appended claim of the utility model.
