Frequently Asked Question
I found that the process connection for temperature transmitter is mandatory information for SIL verification but another transmitters are not. Is there is special reason or technical issue for this?

If you look at the data sheets for temperature sensors you will see that each sensor has 3 columns of connection types, i.e. Thermocouple, RTD 2/3-wire, and RTD 4-wire. Depending on the temperature sensing element, the appropriate failure rate for the sensor is selected. Hence without knowing the type of sensing element (process connection) it is not possible to select the appropriate failure rates. Therefore the process connection for temperature measurements is mandatory.
