Transmitter LKM213
Transmitter LKM213 for Pt100/Pt1000
The LKM213 is an analog measuring transducer for mounting on the standard rail and can be designed for the Pt100 or Pt1000 measuring resistor according to DIN EN 60751. It converts the temperature-dependent resistance value of the sensor into a standard signal of 4...20mA. Lead resistances are compensated by means of a four-wire circuit. A three- or two-wire circuit can also be implemented.The transmitter is supplied calibrated to customer specifications. By means of span and zero controllers, a subsequent fine adjustment can be carried out on site.
Configuration and Selection:
The selection menu is available for standard configuration and can be used for typical settings.

Custom Measurement Ranges:
These can be specified directly in the optional comment field below the selection menu.
Important Conditions: Please ensure that the measurement range falls within the specification limits of the respective sensor and has a minimum span of 20K. This guarantees that the desired range is technically feasible.
Our team will review your order for feasibility. If any issues arise, we will contact you to find a suitable solution.
