Product design: Standards, error avoidance help

Look at how standards and error avoidance helped with applying new level technology to a process sensor for insights into other automation designs.

Courtesy: Endress and Hauser Product design begins with two main foundations: customers' process expectations and developing safe, reliable products. Product certification, including SIL 2/3 certified product lines, provides additional attention to detail.

Frequent device upgrades should be performed in line with the latest requirements. Safety design has been optimized over decades. Product development recommendations begin with customers first. Customers request time-saving safety equipment testing without needing to remove any equipment or shut the plant down.

Emphasis on standardized device platforms increase safety, reliability, and reduce costs for planning, procurement, and operation. Standardized device concepts across all measuring parameters create invaluable benefits in terms of reducing complexity.  

Operation, errors, spares

When creating product design standards across platforms and complying with industry standards, consider:  

Error avoidance

Design around preventing systematic errors. Standards and recommendations for functional safety include detailed descriptions of the requirements for process control safety equipment and its operation. The key point is to prevent systematic errors and reduce the possible residual risk in process control safety equipment to a minimum.
