In-Head Transmitter LKM 143
Pt100/Pt1000, J-head, 4..20mA, 24V supply voltage

The LKM 143 is an analogue transducer for Pt100/Pt1000 temperature sensors acc. DIN EN 60751.
The temperature-sensitive resistance of the Pt100 will be transformed into an analogue current output
of 4..20mA. The LKM 143 can be mounted inside the protection head type J. The span needs at least a range of 20°C. The transducer
LKM 143 is tuned ex works according to the customized requires. Further fine-tuning can be arranged by span and zero controller.
