Transmitter LKM232 for thermocouples
The LKM232 is an analog transmitter with galvanic isolation between input and output for mounting on the standard rail. It can be designed for different thermocouples according to DIN EN 60584 and DIN 43710. It converts the temperature-dependent thermoelectric voltage of the sensor into a standard signal of 0...10V. The temperature compensation takes place in the transmitter itself.
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 ask for individual measuring ranges in advance by clicking 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. Once the individual measuring range has been 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 LKM292, individual measuring ranges are easily possible.
