How to Develop and Qualify Sensors for Arctic Conditions

Posted by Bernd Schneider on Sep 13, 2017 1:09:00 PM

A thank you to Bernd Schneider (Industry Manager Energy – Balluff GmbH Germany) for this weeks blog post on sensors for arctic conditions.

The climatic conditions in the arctic are characterized by cold winters and short summers. There is a large variability in climate and weather: Some regions face permafrost and are ice covered year-round with temperatures down to -40°C / -40°F (and lower), other land areas face the extremes of solar radiation up to +30°C / +86°F in summer.

What is a Mill-Type Cylinder?

Posted by Cowan Dynamics on Jul 26, 2017 11:07:00 AM

Mill-Type cylinders are cylinders designed to fill a need for a more durable, more reliable product to reduce down-time and maintenance costs. Based on design specifications that are not subject to NFPA limitations, the mill-type cylinder has heavy-duty construction with steel flanged end caps, heavy-wall steel tubing, bigger pistons, bearings, advanced gland design, and numerous other features. The mill-type cylinder also has a high pressure rating which is well above industry standards. Together these features assure greater reliability under the severest environmental and operational conditions.

What is Valve Automation?  Part One: Valve Actuators

Posted by Cowan Dynamics on Jul 5, 2017 12:14:00 PM

Industrial valves are flow control devices that are used in pipelines and process plants. The valve’s job is somewhat like that of a tap where the flow of the pipeline is controlled by opening or closing the valve. Valve Automation is the process of adding a valve actuator and control system to the valve. Actuators could be powered by human, electric, pneumatic or hydraulic energy.
