In-Head-Switch Transmitter LKM 105
Pt100, B-head, free configurable, 24V supply voltage
The LKM 105 is a free configurable transmitter for RTD`s Pt100 according to DIN EN 60751.
It observes the temperature dependence resistance with high accuracy and switches the relay if switch temperature is reached. With the help of 6 Dip-switches and a potentiometer one may adjust the LKM 105. The measuring range, the switching temperature, the switching function (open or close) and the hysteresis may be adjusted (see also operating instructions LKM 105). The transmitter is designed for mounting in protection head DIN B. One can also buy this transmitter with custumized adjustments.
