Transmitter LKM467 for Pt100/Pt1000
The LKM467 is a digital, configurable transmitter for mounting in an IP64 housing 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. 12 different measuring ranges can be set via four DIP switches. Lead resistances are largely compensated by means of a three-wire circuit. A two-wire circuit can also be implemented. The components are specially protected by dip coating.
With a zero point controller, a small correction can be made on site.
The following measuring ranges can be configured:
| -100...100°C | -30…70°C | 0...50°C | |
| -50...50°C | -20…80°C | 0...100°C | |
| -40...60°C | -20…150°C* | 0...150°C | |
| -30...60°C | 0...40°C | 0...200°C | *Preset |
