Electrotherm Digital Transducer

LKM 264 Pt100/Pt1000 Digital Programmable Measuring Transducer

The LKM264 is a digital programmable measuring transducer for
Resistance sensors with a 0 to 10 V current output. The LKM 264 transducer has been designed for installation on a 35-mm top hat rail. A PC and programming cable are used to specify sensor type, measuring range, and circuit type.
Minor corrections can be carried out with the zero point controller. The sensor is connected with a 3-lead or 4-lead circuit.
