Management summary
This report summarizes the results of the hardware assessment with prior-use consideration
according to IEC 61508 / IEC 61511 carried out on the pressure transmitter 2600T / 2000T
Series with 4..20 mA output and software version V0.24. Table 1 gives an overview of the
different types that belong to the considered pressure transmitter 2600T / 2000T Series.
The hardware assessment consists of a Failure Modes, Effects and Diagnostics Analysis
(FMEDA). A FMEDA is one of the steps taken to achieve functional safety assessment of a
device per IEC 61508. From the FMEDA, failure rates are determined and consequently the
Safe Failure Fraction (SFF) is calculated for the device. For full assessment purposes all
requirements of IEC 61508 must be considered.
