Dynisco Takes Safety To A New Level

Dynisco Takes Safety To A New Level Dynisco pressure sensors offered with relay switch for added safety and compliance.

Machinery Directive standard EN ISO 13849-1 is a European safety regulation. This is a generic standard defining the requirements for the safety-related parts of control systems. A pressure sensor is a machinery component that is expected to comply under the directive, when they are used in a safety function on a machine. Dynisco offers its popular pressure sensors with an internal relay switch that serves as a redundant safety backup as well as being compliant to the directive through an extension of the line called Guardian Series. Guardian meets the directive without the expense and complication of redundant sensors and external relay modules. Guardian also complies with NFPA 79 clauses A.9.2, A.9.4.1, A.9.4.3.2 as a way of evaluating safety-related aspects of control functions.

Guardian Series sensors are self certified based on the analysis reports of the respected third-party agency, exida™. Guardian Series sensors have undergone extensive FMEDA analysis (Failure Mode Effects and Diagnostic Analysis). Each sensor will meet Performance Level ‘c’ (PL’c’) as defined in the newest Machinery Directive when installed as a single sensor per Category 1. When installed as two sensors per Category 3, Guardian meets Performance Level ‘d’ as defined by the Machinery Directive.

Dynisco branded sensor families that can be ordered as a Guardian sensor include: 

DYNA4, DYN-X, MDA410, MDA420, MDA460, PT410, PT415, PT418, PT420, PT435A, PT450, PT460E, PT460XL, PT462E-M10, PT465XL, PT467E, PT467E-M10, PT467XL, PT480, TPT, TDA, SPX 2xxx, SPX 3xxx, SPX 4xxx, SPX 5xxx

“Achieving PL’c’ compliance on our most popular pressure sensors offers our global customers the confidence functional safety” says Bruce Temple, Dynisco Compliance Officer. “By integrating a safety relay switch into the sensor, users achieve compliance without the expense of redundant sensors, separate modules, extra wiring and extra machine ports. Third party analysis, starting with the FMEDA, allows the user to add compliance to a wide variety of mV and mA-HART sensors, not just restricted to a limited field of products.” continued Temple.
