Electrotherm Digital Transducer | LKM 273

The LKM 273 is a digital configurable measuring transducer for Pt100 / Pt1000 and is designed for installation on a 35 mm top hat rail. This transducer has a 20 to 20 mA current output. To set 13 different measuring ranges use a 4 DIP switches. You can make minor corrections for the transducer with a zero point controller. The sensor for the LKM 273 is detected automatically and connected with a 3-/2- lead circuit.
