Pressure Transducers: What are They and What to Consider

Pressure transducers can be used in off-road equipment, construction machinery, performance racing, railroads, engines, and other applications where a transducer may be exposed to shock and vibrations. Transducers can be exposed to shock and vibrations through normal use, as well as during maintenance. Although not all applications subject a transducer to shock or vibrations, these devices tend to be very sensitive and their ability to accurately read pressure can be affected easily.

Drinking Water Regulation

For the past few years, questions about the safety of drinking water have constantly been in the news. Following the 2014 crisis in Flint, Michigan, cities across the U.S. launched their own investigations to determine whether their own drinking water supplies were safe. Drinking water is contaminated when old lead pipes corrode, allowing lead and other chemicals to enter the water supply. While lead is most dangerous when ingested, even outside of potable water applications there are still strict regulations regarding the materials and chemicals that may come in contact with water. This minimizes risk of contamination. Continue reading “Drinking Water Regulation”

Control Valve Sizing

Hi-Flow™ Valve Application

Control valves are used to change process conditions such as flow, temperature, level, and pH. A complete control system would include a sensor, controller, positioner or current to pressure transducer, and control valve. Globe valves, such as the Dwyer Hi-Flow™ Series, are a common type of control valve. In the example shown, a Hi-Flow™ control valve is controlling temperature by varying the amount of steam or cold water added to the process.

What is Wastewater, and How is it Treated?

Every day, billions of gallons of wastewater are collected from our homes, businesses, and industries. Wastewater is exactly what it sounds like: water that has already been used and disposed of via a tub, toilet, sink, or storm drains. Because it is full of contaminants that make the water no longer suitable for use, it is collected in the sewer system and delivered to plants for treatment to make the water safe to be returned to the environment.
