Description
Technical field
The utility model relates to the measurement instrument technology, particularly relates to a kind of technology of touch-induction-type guidance panel of electromagnetic flowmeter.
Background technology
Electromagnetic flowmeter is a kind of instrument that is used to measure fluid flow, and its use occasion is the occasion that dust is many, humidity is high, so electromagnetic flowmeter is all higher to requirement dustproof, moistureproof aspect.
The traditional electrical magnetic flowmeter is used for the cover cap that cover cap is lived guidance panel in order to reach requirement dustproof, moistureproof aspect, all to be provided with, and transparent windows is housed on the cover cap.When operating personnel will operate the traditional electrical magnetic flowmeter, need take off cover cap earlier, then could be through input data of the button on the guidance panel or operating parameter, operation refills upper cover after accomplishing, in order to avoid external dust and moisture get into.This mode of cover cap protection guidance panel of utilizing of traditional electrical magnetic flowmeter makes its operation very inconvenient; And open in the process that cover cap operates guidance panel; External dust and moisture still can get into, thereby have influence on the serviceable life of each button on the guidance panel.
The utility model content
To the defective that exists in the above-mentioned prior art, the utility model technical matters to be solved provides a kind of operating aspect, and the touch-induction-type guidance panel of the electromagnetic flowmeter of button long service life.
In order to solve the problems of the technologies described above; The touch-induction-type guidance panel of a kind of electromagnetic flowmeter that the utility model provided; Comprise the printed-wiring board (PWB) that is printed with button inputting circuits; And be installed at least one button on the printed-wiring board (PWB), it is characterized in that: the base plate face of said printed-wiring board (PWB) is covered with one deck and covers copper mesh;
Said button is the capacitive induction electrode, and each button is installed on the top board face of printed-wiring board (PWB);
Be provided with in the button inputting circuits on the said printed-wiring board (PWB) and a plurality of one to one key induced loops of each button, each key induced loop all connects corresponding key through the elasticity thimble;
The top board face of said printed-wiring board (PWB) be provided with one cover in each button transparent cover plate, the thickness of this transparent cover plate is less than the distance that detects of each button.
Further, also be provided with on the said printed-wiring board (PWB) and a plurality of one to one induction pilot lamp of each button and each key induced loop, each induction pilot lamp all inserts corresponding key induced loop.
The touch-induction-type guidance panel of the electromagnetic flowmeter that the utility model provides; Adopted the capacitive induction electrode as operation push-button, and be provided with the corresponding key loop inductance, and each button and external environment condition have been separated through transparent cover plate at printed-wiring board (PWB); Operating personnel's only with hand refer to touch on the transparent cover plate with the target button over against the zone; Can make the corresponding key induced loop of target button produce the electric signal that button is pressed, thereby realize that operation is very easy across the operation of transparent cover plate to the target button; And avoided the entering of external dust and moisture in the operating process, can prolong the serviceable life of each button.
