Transmitter LKM113 for Pt100/Pt1000
The LKM113 is a digital, configurable transmitter for mounting in the connection head type B 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 4...20mA. Four DIP switches can be used to set 12 different measuring ranges. Lead resistances are largely compensated by means of a three-wire circuit. A two-wire circuit can also be implemented. Due to the complete encapsulation with polyurethane, the components are particularly protected.
With a zero point controller, a small correction can be made on site.
The following measuring ranges can be configured:
| -100...100°C** | -20...150°C | 0...300°C | |
| -50...50°C** | 0...50°C* | 0...400°C** | |
| -40...60°C** | 0...100°C | 0...500°C** | *Preset |
| -30...70°C** | 0...200°C | 0...600°C** | **Pt100 only |
