Transmitter LKM410 for thermocouples
The LKM410 is an analog transmitter and can be designed for various thermocouples according to DIN EN 60584 and DIN 43710. Its design is ideally suited for mounting in tubular housings. It converts the temperature-dependent thermoelectric voltage of the sensor into a standard signal of 4...20mA. The temperature compensation takes place in the transmitter itself.
The transmitter is supplied calibrated to customer specifications. It can be supplied either with the Hirschmann plug type GSP or without plug. With this arrangement, customer-specific probes with integrated transmitter, such as our Type506, can be realized. 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 ordering process.
