Transmitter LKM232
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.
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 200K. 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.
