In-Head Transmitter LKM 141
Thermocouples, J-head, 4..20mA, 24V supply voltage
The LKM 141 is an analogue transducer for thermo couples acc. DIN EN 60584 or DIN 43713.
The temperature-sensitiv voltage will be transformed into an analogue current output of 4..20mA.
The LKM 141 can be mounted inside the protection head type J.
The span needs at least a range of 200°C.
The transducer LKM 141 is tuned ex works according to the customized requires. Further fine-tuning can be arranged by span and zero controller.
