In-Head Transmitter LKM 101
Thermocouples, B-head, 4..20mA, 24V supply voltage
The LKM 101 is an analogue transducer for thermocouples acc. DIN EN 60584 or DIN 43713.
The temperature-sensitive voltage will be transformed voltage-linearly into a current output of 4..20mA. The transducer LKM 101 is to be mounted inside the protection head type B.
The working range of the instrument needs a span of at least
200°C. The transducer LKM 101 is tuned within a customized span ex works. Further fine-tuning can be arranged by adjusting zero and span.
