In-head transmitter LKM 141 for thermocouples with output signal 4...20mA for mounting in connection heads form J

The LKM 141 is an analog transmitter for thermocouples according to DIN EN 60584 or DIN 43710. It converts the temperature-dependent thermoelectric voltage linearly into a standard current signal of 4...20mA. Depending on the measuring range and thermocouple type, the signal is adjusted in such a way that the temperature errors are minimized. The transmitter is designed for mounting in the measuring head form J (F). An adjustment range of approx. 200 °C (depending on the thermocouple type) is required for the span. The LKM 141 transmitter is factory calibrated to customer specifications. Subsequent fine adjustment can be carried out by means of span and zero controllers.
