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.
