Transmitter LKM214
Transmitter LKM214 for Pt100/Pt1000
The LKM214 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 0...10V. 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.The selection menu is available for configuration.
Please request individual measuring ranges beforehand using the >>Ask about product<< button.
In the case of analog transmitters, it may occasionally be the case that the desired measuring range cannot be realized. If the individual measuring range is confirmed by us, it can be entered in the >>YOUR COMMENTS<< field at the end of the order process.
Our tip: With the digital equivalent LKM264, individual measuring ranges are easily possible.
