Transmitter LKM263 for resistance sensors
The LKM263 is a digital, programmable measuring transducer for mounting on the standard rail and can be set for various resistance sensors according to DIN EN 60751. It converts the temperature-dependent resistance value of the sensor into a standard signal of 4...20mA or inverse 20...4mA. Lead resistances are compensated by means of a four-wire circuit. A three- or two-wire circuit can also be implemented.
The transmitter is delivered configured according to the customer's requirements. Subsequent changes of the sensor and measuring range can be made with our communication interface "LKM S1" with adapter A1 and a PC. The required program is available free of charge in the tab "Downloads".
With a zero controller a small correction can be done on site. Additionally an offset can be set by software.
The selection menu is available for configuration.
When entering your individual measuring range, please note the measuring range of the selected sensor. This can be found in the technical data. The minimum span is 20°C.
