THE ASSESSMENT OF COMPANY-LEVEL CONTROLS is a critical part of complying with section 404 of Sarbanes-Oxley. The PCAOB says public companies must assess the design and operating effectiveness of these ...

Hydrostatic pressure produced by the water column at the bottom of the controlled liquid reservoir uses the trapped air in the measurement tube to produce the same amount of pressure on the sensor. At ...

This reference design describes a cost-effective, low-power liquid-level measurement data acquisition system (DAS) that use a compensated silicon pressure sensor and a high-precision delta-sigma ADC.

The new CLD/P Series brings these new features together with a simpler than ever to use interface. The multi-function controllers allow easy monitoring of two to four level points, with simple ...

Feedwater control valves play a critical role in boiler operation. One important parameter of their design is the pressure drop at the rated condition as well as off-design conditions. However, ...

On my first project as a combustion control engineer, I was responsible for loop checks and for watching the experts tune the system controls. The first loop I tried to tune solo was the drum level ...

Machine control systems, which combine positioning sensors — both GNSS receivers and inertial systems — with computer displays, give operators better insight into and control over their work. Whether ...

The ALmix Split-Level Control House is designed to provide a safe, refined, and fully mobile environment for your asphalt plant operators, plant automation systems, and load-out. The ALmix Split-Level ...
