Din-Rail Transmitter LKM 223
Pt100/Pt1000, rail mounting, 4..20mA, 24V Supply voltage

The LKM 223 is an analogue transducer for Pt 100/Pt1000-temperature sensors according
DIN EN 60751. The temperature-sensitive resistance will be transformed into an analogue current output of 4...20mA. The transducer LKM 223 can be mounted on customary rail systems.
The LKM 223 has been tuned ex works according to customized requires. Further fine-tuning can be arranged by span and zero controller.
