ABB PS130/6-75-P bi-plane radial vibration monitor
The touch screen uses pressure sensing for control. The main part of the resistance touch screen is a resistance film screen that is very compatible with the surface of the display, which is a multi-layer composite film, which takes a layer of glass or hard plastic plate as the base layer, and the surface is coated with a layer of transparent metal oxide (transparent conductive resistance) conductive layer. It is then covered with an outer, hardened, smooth, anti-rub plastic layer, and its inner surface is also coated with a coating, and between them there are many small (less than 1/1000 inch) transparent isolation points separating the two conductive layers. When the finger touches the screen, the two conductive layers are in contact at the touch point, the resistance changes, and the signal is generated in the X and Y directions, and then sent to the touch screen controller. The controller detects this contact and calculates the position of (X, Y), then operates in a manner that simulates a mouse. This is the basic principle of resistive technology touch screen. The key to the resistance touch screen is the material technology, the commonly used transparent conductive coating materials are: A, ITO, indium oxide, weak conductor, the characteristic is that when the thickness drops to 1800 angms (angms =10-10 meters) below will suddenly become transparent, the light transmittance is 80%, and then thin down the light transmittance decreases, and rises to 80% when the thickness of 300 angms. ITO is the main material used by all resistive technology touch screens and capacitive technology touch screens, in fact, the working surface of resistive and capacitive technology touch screens is ITO coating.
B, nickel gold coating, the outer conductive layer of the five-wire resistance touch screen uses a malleable nickel gold coating material, the outer conductive layer due to frequent touch, the use of malleable nickel gold material is intended to extend the service life, but the process cost is relatively high. Although the nickel gold conductive layer is good in ductility, it can only be used as a transparent conductor, and is not suitable for use as the working surface of the resistance touch screen, because it has high conductivity, and the metal is not easy to achieve a very uniform thickness, it is not suitable for voltage distribution layer, and can only be used as a probe layer.
1.1 Four-wire resistance screen
The two transparent metal layers of the four-wire resistance analog technology operate with a constant voltage of 5V in each layer: one vertical and one horizontal. A total of four cables are required. Features: High resolution, high speed transmission response. Surface hardness treatment, reduce scrapes, scratches and chemical treatment. With smooth surface and fog surface treatment. One correction, high stability, never drift.
