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 standard configuration and can be used for typical settings.
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.
