2. Design and function
2.1 Description
This resistance thermometer, through a wide variety of process connections, enables
trouble-free connection to many different processes.
3- or 4-wire platinum measuring resistors in accuracy classes A and B per DIN EN 60751
serve as sensors.
Transmitters built into the connection head are capable of making various output signals
available, for example 4 ... 20 mA or HART®protocol.
