The T32 is the flagship of WIKA’s temperature transmitters and a bestseller, too: The instrument of serial number 1 000 000 was recently manufactured. As one of the first temperature transmitters worldwide, the T32 has complied with all requirements of the standard for functional safety to IEC-61508, also known as SIL (Safety Integrity Level). The WIKA in-house development was certified as part of a full assessment by TÜV Rheinland as independent body.
For successful SIL certification, the development process for the T32 had to follow exactly the V model of IEC-61508. In addition, it was mandatory to implement an extensive diagnostic functionality for detecting critical error states in instrument operation, which allows the plant manager to bring his process to a safe state in case of malfunction. The function comprises, among other things, monitoring the sensor lead resistances, sensor monitoring, continuous microcontroller self-diagnostics, and hardware monitoring. The functionality is rounded off by very good long-term stability and excellent EMC characteristics.
The development process required for SIL certification in accord-ance with the V model was consistently implemented at WIKA for the first time as part of the T32 project. Compared with conventional product development, the standard requires much higher levels of documentation and product validation expenditure.
Excellent quality figures
In retrospect, this additional expenditure has paid off by giving excellent quality figures.
For the SIL generation of the T32 (the third overall), for years the return ratio has been in the single figure ppm range, and its longstanding, proven reliability, even in demanding industrial environments, has impressed customers.
