Abstract
The utility model relates to an atmospheric corrosion wet time sensor comprising two groups of copper foil conducting wires between which a switch, a battery, an ammeter and a variable resistor are connected in series, wherein, a data acquisition output interface is connected in parallel with the resistor and the ammeter. The utility model is characterized in that the two groups of comb-shaped copper foil conducting wires mutually insulated and interpenetrated are made of printed circuit boards. The utility model can be accurately manufactured with simple manufacturing process, remarkably raises the sensitivity and the repeatability of the sensor, and has the advantages of small size, high sensitivity, good consistent performance, low cost and convenient mass production in multiple standards.
Description
The utility model relates to a kind of sensor, particularly relates to a kind of atmospheric corrosion wetting time sensor.
Wetting time is to measure the important parameter of metal corrosion speed in atmosphere.Wetting time is not only relevant with the relative humidity of environment, and is also relevant with kind, the metallic surface state of metal.Traditional atmospheric corrosion wetting time sensor has two groups of superimposed adhesive solidifications of different types of foil mutually insulated, and side of sanding and polishing is as measuring workplace, and its shortcoming is that sensitivity is low, and the cost of processing foil is very high.Each distance between commutator segments is difficult to make very little and even, need make by hand, makes complexity, and the time is long, and success ratio is low, is difficult to realize producing in enormous quantities.Because different metallic surface tension force is different with wettability, thereby measurement result is closely related with this sensor self property, and data reappearance is bad, disperses very much, is difficult to compare mutually.
The purpose of this utility model provides a kind of atmospheric corrosion wetting time sensor, and it can overcome the above-mentioned shortcoming of existing sensor.
A kind of atmospheric corrosion wetting time sensor, comprise two groups of copper pool leads, serial connection one switch, battery, reometer and variable resistor between these two groups of copper pool leads, a data collection output interface is in parallel with this resistance and reometer, it is characterized in that described two groups of copper pool lead is the lead by print circuit plates making, they all are pectination, mutually insulated, and intert mutually.
Copper pool lead of the present utility model can accurately be made, technology is simple, width, spacing and metal surface state can both strict be controlled, and spacing can be very little, significantly improved the sensitivity and the reappearance of sensor, and volume is little, highly sensitive, consistency of performance is good, and cost is low, is convenient to many specifications and produces in enormous quantities.
Below by embodiment and description of drawings the utility model.
Accompanying drawing is a structural representation of the present utility model.
Present embodiment comprises two groups of copper pool leads 2 and 3 of making on printed circuit board (PCB), serial connection one switch 4, battery 5, reometer 8 and resistance 6,7 between two groups of copper pool leads 2 and 3, data gather output interface 9 and this resistance 6 and 7 and reometer 8 in parallel, it is characterized in that described two groups of copper pool lead 2 and 3 is pectination, mutually insulated, and intert mutually.
Circuit width of the present utility model can reach 0.1 millimeter, 0.02 millimeter of spacing.As required, on electric conductor 2 and 3, plate one deck gold, silver, iron or zinc film.
According to circuit of the present utility model, signal can directly be imported registering instrument or computing machine, to realize automatic data collection and monitoring.If because of higher dewfall of air humidity or rainfall snowfall, will make copper pool lead 2 and 3 short circuits, make the external circuit conducting, 8 in reometer can show electric current, shows that lead (probe) 2,3 surfaces are wetting.The resistance of regulating variable resistor 7 can change the sensitivity of sensor.Registering instrument or computing machine be the wetting time on record lead (probe) 2,3 surfaces automatically.Analyze the rule of wetting time and cooperate other data can calculate atmospheric corrosion speed.
