Strain Gage Load Cells Meet EN ISO 13849 / IEC 61508

The BLH Nobel brand of Vishay Precision Group announces that four of its strain gage load cell product families are now available with EN ISO 13849 and IEC 61508 functional safety certifications. The EN ISO 13849 functional safety standard incorporates statistical analysis to help better predict component, device and circuitry reliability within the safety-related parts of industrial machinery control systems. This determination represents the probability of failure to danger over time, expressed as a performance level (PL). The IEC 61508 standard for electrical/electronic/programmable electronic safety-related systems further defines methods to achieve product functional safety. This allows OEMs to demonstrate a certain overall safety integrity level (SIL) within their system designs.

 

 The strain gage load cell product families include models with or without current loop output, as well as those featuring redundant configurations. Most families with functional safety certifications are further available with ATEX, CSA, FM, IECEx, cFMus and CE approvals. The certifications allow the load cells to be specified within a wider range of critical applications, including crane weighing and overload monitoring; process industry weighing and monitoring; offshore tank weighing; machinery monitoring; and safety-critical weighing and force measurements.
