WebSensor resolution is calculated from sensor size and effective megapixels. It's slightly higher than maximum (not interpolated) image resolution which is usually stated on camera specifications. Sensor resolution is used in pixel pitch, pixel area, and pixel density formula. For sake of simplicity, we're going to calculate it in 3 stages. 1. WebOpacity sensors used for stack monitoring are online devices which are affixed to the process stream; these are commonly known as transmissometers. They typically consist of a transmitter, which directs emitted radiation through the stream, and a receiver which measures the transmitted radiation.
