Abstract
The utility model discloses a sensor for measuring sedimentary liquid fog amount, in particular to a sensor for measuring sedimentary salt-fog amount, belonging to the field of environmental test apparatuses, comprising a collecting funnel, a cylindrical inner electrode whose surface is sheathed with an insulating coat, a cylindrical outer electrode which is concentric to the inner electrode, a end cover and a base. Through the detection to the capacitance quantity between the inner and the outer electrodes, the real-time sedimentary amount of the liquid fog can be determined. The utility model is particularly suitable for measuring the sedimentary amount of the salt fog of the salt fog corrosion test apparatus in real time, and is used as a sensor for rainfall digital measuring apparatus.
Description
The utility model discloses a kind of sensor of measuring liquid mist settling amount, particularly measure the sensor of salt fog settling amount, belong to the environmental test equipment field.
The salt fog settling amount of existing salt spray corrosion test equipment is measured, and normally collection funnel and graduated cylinder is placed in the testing equipment and carries out, with the naked-eye observation reading.Because during test, fog is steaming in the equipment, does not see the scale of graduated cylinder, so that can not in time observe settling amount.Some external small-sized salt-mist corrosion testers are to collect spray film and guide in the outer graduated cylinder of case with band tubing and observe being placed on collection funnel in the case.Because flexible pipe to the adhesion of spray film, consequently can cause bigger reading error.For large-scale chamber or testing laboratory, this method will be oversize because of the flexible pipe of drawing, forfeiture precision and can not using.For the mensuration of rainfall amount, prior art is still the method that adopts traditional funnel to add graduated cylinder.
The purpose of this utility model is to provide a kind of liquid mist settling amount to measure the sensor of usefulness.It both can avoid the measuring error that causes because of flexible pipe in the prior art, again the element that provides the basis for the digital measurement of realizing liquid mist settling amount and control.
The utility model can be implemented with following manner:
The collection funnel of a taper (1) is stored in the spray film of sedimentation in the tubular reservoir of being made up of columnar external electrode (3) and columniform interior electrode (4).The bottom of external electrode (3) can be flat or recessed, the bottom of correspondingly interior electrode (4) can be flat, it also can be arc surface, at the inside of the outside surface of interior electrode (4) or external electrode (3) lining one deck insulating medium layer (5), the going to the bottom of interior electrode (4) apart from 2～10 millimeters at the interior end of external electrode (3).
When the sedimentation of liquid mist, every one deck insulating medium (5) and fluid column (12), therefore interior electrode (4) has just become a cylindrical capacitor with external electrode (3) between interior electrode (4) and the external electrode (3).It is composed in parallel by two parts capacitor: the part of fluid column (12) is arranged and do not have the part of fluid column (12).When the height of fluid column (12) surpassed the bottom of interior electrode (4), its capacitance change will be directly proportional with the high variable quantity of fluid column (12).When the sedimentation of liquid mist,, and then record the real-time settling amount of liquid mist as long as measure the variable quantity that the changes in capacitance amount just can record fluid column (12) height indirectly by extension line (8) and (14) of inside and outside electrode.
The end cap of being made by insulating material (2) is used for supporting funnel (1) and fixing interior electrode (4).The bore of collection funnel (1) is 210 millimeters of φ 90～φ, and its tapering is 60 °～120 °, is made by metal or plastics.Make with conductive material inside and outside electrode (4) and (3).The base that is made of plastics (6) is used for supporting whole sensor.Be installed in whether level of placement that two mutually perpendicular tube bubbles (9) on the base (6) are used to refer to sensor.And the stone bolt (7) of base (6) bottom is to be used as horizontal adjustment.
Overfolw hole (13) is used for overflowing too much spray film, and taphole (11) is then as quantitative or regularly tapping, so that carry out duplicate measurements.Overfolw hole (13) and taphole (11) are dispensable, when being provided with taphole (11), should add a stopper (10) or miniature electromagnetic valve, so that the control tapping.
Accompanying drawing 1 is a structural representation of the present utility model.
The utility model will be further described below in conjunction with embodiment.
1. when measuring the salt fog settling amount, the diameter of collection funnel (1) is 101 ± 0.1 millimeters of φ; The diameter of collection funnel when measuring the amount of rainfall (1) is 200 ± 0.3 millimeters of φ.
2. the external diameter of interior electrode (4) is 22 millimeters of φ 18～φ, highly is 140～148 millimeters, best external diameter and highly be 19.5 millimeters of φ and 144 millimeters.The thickness of the insulating medium layer (5) of outside lining is 0.2～0.5 millimeter, and material is tygon or teflon.
3. external electrode (3) is flat cylindrical shape, and its internal diameter is 30 millimeters of φ, highly is 155 millimeters.
