In-Head Transmitter LKM 103
Pt100/Pt1000, B-head, 4..20mA, 24V supply voltage

 

The LKM 103 is an analogue transducer for Pt100/Pt1000 sensors acc. DIN EN 60751. The temperature sensitive resistance will be transformed into an extreme precise, temperature-linear current output of 4..20mA. The transducer LKM 103 can be mounted inside the protection head type B. The span needs at least a working range of 20°C. The transducer
LKM 103 is tuned acc. customized needs ex works. Further fine-tuning can be arranged by span and zero controller.
Please note: Using Pt 100 in 2-wire connection clamps 4 and 5 must be jumpered!
