Many industrial plants use our standard "blue" product line, the One Series Smart Electronic Switch. This product has been tested for stringent environmental conditions and harsh workplaces and it has achieved the most rigorous certifications in the market. However, some production plants may have a higher standard.
Field Safety Transmitter
ONE Series field safety transmitter became popular due to its cost-effective and more rigorous instruments for installation
The "yellow" ONE Series is the field safety transmitter. It is an industrial functional safety-certified product. This means it complies with the IEC 61508 safety standard. Functional safety takes an extra step in validating the absence of unreasonable risk due to hazards caused by malfunctioning behavior; it also takes a holistic view to the safety of every element in the process chain.
This applies when safety is a mandatory requirement and formalized as a norm in the entire plant. This standard addresses rigorous diagnostics, extreme failure modes analysis, and examination of every single hazard possible to put the system in a safe state.
Functional safety is an entire paradigm and requires a process of function reviews (HAZIDs, HAZOPs, etc). It also requires safe management of software errors, hardware failure estimation, and assessment of risk reduction. Designs that comply with a functional safety standard are deemed to be better at handling failures.
Entire Safety System
Products designed under this standard are broadly used in other installations, even if they are not safety regulated. This is the case for the ONE series field safety transmitter that became popular as a cost-effective and yet more rigorous instrument for any installation.
Additionally, the ONE Series field safety transmitter is an entire safety system with: a logic solver, a sensing element, and actuation. So for the next project, don’t hesitate to get the best product for the most challenging needs.
