However, the same combination that makes outdoor activities pleasant can wreak havoc in industrial facilities. Temperature and humidity swings create condensation on concrete slab floors common in many industrial settings. Known as âsweating slab,â this sheen of water can cause big issues with employee safety and product integrity. Following are a few of the common questions about sweating slab, and an example of a company that successfully solved its perspiration problem. What is sweating slab? Condensation occurs when warm, moist air contacts a cold surface.
Electrical impedance is the measure of the opposition that a circuit presents to a current when a voltage is applied. In quantitative terms, it is the complex ratio of the voltage to the current in an alternating current (AC) circuit. Impedance extends the concept of resistance to AC circuits, and possesses both magnitude and phase, unlike resistance, which has only magnitude.
impedance is a measure of how much of the electrical signal can pass through a cable at any given time. Impedance of a cable is affected by the type and size of conductors used in a cable, the spacing and. orientation of the component cables, and the insulation surrounding the conductors. When designing a CCTV video surveillance system, it is extremely important to match the impedance of. the source, cabling and load.
