These systems come with catalytic or electrochemical sensors to monitor for methane, chlorine, hydrogen sulfide and oxygen deficiency. They have a stand-alone design with built-in alarms and relays, automatic zero and span calibration, standard 4-20mA and RS485 Modbus digital ports, remote access and adjustment features, and a full-featured display with status indicators. They are made for monitoring pump rooms, screen chambers, wet wells, grit pump and wash areas, chlorine storage and metering area, and other work areas in wastewater treatment plants.
In many engineering workplaces, there’s a generational conflict between recent engineering graduates and older, more experienced engineers. However, a recent study published in the psychology journal Cognition suggests that both may have something to learn from another group: 4 year olds.
Conventional wisdom holds that MIT, Cal Tech, and Stanford are three of the country’s best undergraduate engineering schools. Unfortunately, when conventional wisdom visits the topic of best engineering schools, it too often leaves out some of the most distinguished programs that don’t happen to offer PhD-level degrees.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
