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 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 …
The two definitions of MTTF and MTBF differ only slightly. Written out, the two acronyms read as follows: Mean Time To Failure (MTTF) – i.e., the component/instrument will be replaced, following a failure Mean Time Between Failures (MTBF)– mean time between …
