An important parameter in the use of pressure sensors in safety devices is the so-called “Diagnostic Coverage” (DC). However, since single-channel, in particular, but also two-channel safety circuits often malfunction or may be defective, a known diagnostic …
Customers often ask us: “Can my product be part of a safety function? Which standards or directives apply in this case?” The most important safety directives and standards available today are SIL (Safety Integrity Level) and PL (Performance Level). These …
When using pressure sensors in safety-relevant applications, sooner or later one must ask the question whether the SIL evaluation of the proposed pressure sensor is sufficient for the application. Often, the user tends to favour pressure sensors with higher SIL …
When using pressure sensors and pressure transmitters, our customers often ask for explanations of frequently used terms and abbreviations in connection with "SIL applications". SIL – which means Safety Integrity Level, and PL, which means Performance Level, are …
For the pressure transmitter IS-20 with the ignition protection type ia (intrinsically safe) and ATEX approval, the safety-relevant data for SIL applications have been determined and summarized in the additional instructions "safety-related data" (PDF). These …
