Programmable transmitter track mounting

The LKM 274 is a digital configurable measuring transducer for Pt100/Pt1000 with a 0 to 10 V output. This transducer has been designed for installation on a 35 mm top hat rail. You can set 13 different measuring ranges using 4 DIP switches. As a user you can make minor corrections with a zero point controller plus the sensor is connected with a 3-/2- lead circuit.
Measuring ranges that can be configured
-100 to 100°C, -50 to 50°C, -40 to 60°C, -30 to 70°C, -20 to 150°C
