Transmitter LKM274 for Pt100/Pt1000
The LKM274 is a digital, configurable transmitter for mounting on the standard rail and is designed for Pt100 and Pt1000 measuring resistors according to DIN EN 60751. The sensor is automatically recognized. It converts the temperature-dependent resistance value of the sensor into a standard signal of 0...10V. Four DIP switches can be used to set 13 different measuring ranges. Lead resistances are largely compensated by means of a three-wire circuit. A two-wire circuit can also be implemented.
The following measuring ranges can be configured:
-100...100°C |
-20...150°C |
0...250°C |
0...600°C** |
-50...50°C |
