Understanding the implications of adiabatic and isothermal flow assumptions is necessary to have confidence in when to use such assumptions Every engineer uses assumptions because every analysis has an overabundance of variables to consider. Often, there are just too many…
Airset regulators are seemingly simple devices, but care must be taken to ensure the right devices are specified, particularly in safety instrumented systems Chemical plants and other heavy industrial facilities typically contain many pneumatically controlled valves, actuators and instruments. Airset…
Storage tanks that are freely vented to the atmosphere are known as aboveground atmospheric storage tanks (ASTs). ASTs have a vertical cylindrical configuration and can be identified by the open vent nozzle on the tank roof. This one-page reference outlines…
This company has expanded its HiLobe series Roots pumps (photo), which are available in a broad spectrum of pumping speeds and applications. HiLobe Roots pumps are particularly suited for rapid evacuations (lock chambers or leak-detection systems) and for general coating…
Genesis Network (photo) is a new system that provides site-wide operational awareness and supervisory control of heat-trace systems. Users can easily monitor, maintain and troubleshoot even the largest heat-trace systems that may include over 10,000 heat-trace circuits. The Genesis Network…
The new Rosemount 8800 Quad Vortex flowmeter (photo) is specifically designed to meet stringent safety standards in environments and applications that require safety instrumented systems (SIS). The flowmeter is said to be the first in the industry with quadruple sensors…
Washdown-ready, smooth-body gear units, motors and variable frequency drives (photo) bring an innovative alternative to expensive, bulky stainless steel, while nsd tupH provides these units with even greater protection for food. The nsd tupH sealed-surface conversion system is not a…
Last month, this company introduced the new generation of its intrinsically safe 4G/LTE Android smartphone Smart-Ex 02 (photo). With a large 5-in. display and smart ergonomics, the Smart-Ex 02 is said to be the most advanced explosion-proof smartphone for Zone…
My Tech Support Portal (photo) provides continuous access to online resources and tools to perform immediate self-service and to manage their support and service cases. In addition to phone support, the My Tech Support Portal offers 24/7 access to a…
The new CDS Series of non-metallic, curved-top motor-disconnect switches (photo) features a curved profile to eliminate standing water and minimize contaminant buildup in food processing and cleanroom operating environments. In addition to its curved profile, the CDS Series features a…
