4. Design and function
4.1 Description
The field instruments are 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 field instruments meet the requirements of:
■ Explosion protection (depending on the version)
■ Electromagnetic compatibility in accordance 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)
Versions
