4. Design and function
4.1 Description
The temperature transmitter is used for converting a resistance value
or a voltage value into a proportional current signal (4 ... 20 mA).
Thus the sensors are permanently monitored for their fault-free
operation.
The transmitter meets the requirements for:
■ Functional safety per IEC 61508/IEC 61511-1 (depending on the
version)
■ Explosion protection (depending on the version)
■ Electromagnetic compatibility in accordance with NAMUR
recommendation NE21
■ Signalling at the analogue output in accordance with NAMUR
recommendation NE43
■ Sensor burnout signalling in accordance with NAMUR
recommendation NE89 (corrosion monitoring sensor connection)
4.2 Operation in safety-related applications
The model T32.xS.xxx-S (SIL version) has been
designed for use in safety-related applications.
The marking of this design variant is given in chapter 2.6 “Labelling,
safety marking”. For operation in safety-related applications the
additional requirements must be observed (see safety manual
“Information on functional safety of model T32.xS”). The instructions
contained in this must be followed without fail.
