In-head transmitter LKM 143 for Pt100 / Pt1000 with output signal 4...20mA for mounting in connection heads form J
The LKM 143 is an analog measuring transmitter for Pt100 / Pt1000 measuring resistors according to DIN EN 60751. It converts the temperature-dependent resistance of the sensor into a current signal of 4...20mA in a highly accurate temperature-linear way. The LKM 143 can be calibrated to the range specified by the customer. The fine adjustment is done by a span and zero controller. Minor corrections on site are thus easily possible. The distance of the mounting holes is specified with 19mm.
