DIN rail Transmitter LKM 212 for thermocouples with output signal 0...10V

 

The LKM 212 is an analog transmitter for rail mounting. It can be designed for different thermocouples according to DIN EN 60584 or DIN 43710. It converts the temperature-dependent thermoelectric voltage of the sensors into an output voltage signal of 0...10V. The temperature compensation takes place in the transmitter itself. It is delivered from the factory calibrated to customer specifications. Depending on the measuring range and thermocouple type, the adjustment is carried out 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.
