Transmitter LKM 211

DIN rail transmitter LKM 211 for thermocouples with output signal 4...20mA

 

The LKM 211 is an analog transmitter for mounting on the standard rail. It can be designed for various thermocouples according to DIN EN 60584 and DIN EN 43710. It converts the temperature-dependent thermoelectric voltage of the sensors into a standard signal of 4...20mA. The temperature compensation takes place in the transmitter itself. The transmitter is delivered from the factory calibrated to customer specifications. Depending on the measuring range and thermocouple type, the adjustment is performed in such a way that the occurring temperature errors are minimized. A voltage-linear adjustment for further processing of the measured values in the PC or PLC can also be carried out. This should be specified when ordering. A span and zero controller enables subsequent fine adjustment.
