Transmitter LKM 102

In-head transmitter LKM 102 for thermocouples with output signal 0...10V for mounting in connection heads form B

 

The LKM 102 is an analog transmitter for thermocouples according to DIN EN 60584 and DIN43710. It is suitable for direct connection to evaluation devices with voltage input such as PLCs or AD converter cards in PCs. The thermoelectric voltage generated by the sensor is converted into an output signal of 0...10V. The temperature compensation takes place in the transmitter itself. The transmitter type 102 is delivered calibrated according to customer specifications. Depending on the measuring range and the type of thermocouple, the adjustment is carried out in such a way that the occurring temperature errors are minimized. Smaller corrections can be carried out on site by means of a zero and span controller. The LKM 102 can also be supplied voltage linear adjusted for further processing and linearization of the measured values in a PLC or a PC.
