Increasing demands on the flexibility of industrial production plants in the (petro-)chemical, pharmaceutical, food and beverage industries call for future-proof automation systems.
Processes are optimized to the maximum with the help of process analytical technology (PAT) and must be economical along the entire value chain.
This requires a flexible and cost-efficient integration of measuring interfaces at various points in the process, which continuously analyze and monitor the production.
When does the multiplexer become profitable?
With a focus on liquid measurement, the main application area of the Multiplexer FMX is online installations for measurements in transmission or transflectance. This way online measurements can be realized in different process steps and on several production lines with only one spectrometer.
The integration can be carried out efficiently and customer-specific
Reduction of investment costs per measuring point
High transmission & equally good performance on all channels
Flexible at any time expandable up to 16 measuring points
The optical switching between different channels of the multiplexer makes it possible to use several measuring points with one instrument. This enables the user to forward measurement signals from several spectroscopic sample interfaces to a single process spectrometer.
The investment costs for the installation and connection of one measuring point are significantly reduced. Thus, up to 16 different probes and measurement cells can be installed in a space-saving, simple and economical way. Due to the efficient connection of several measuring points, the use of a multiplexer already pays off from two measuring points.
The following is an example of the investment costs with and without the use of a multiplexer depending on the number of measuring points. The implementation costs are always the same and constant in both cases.
The »Multiplexer FMX« gives you stable, precise and reproducible measurement values. This simplifies the method transfer to other measuring points in the production plant and reduces the workload. Overall, the multiplexer contributes significantly to process transparency and enables you to achieve optimum control.
The integrated high-quality optics with retroreflector always redirect the light beam optimally and thus ensures high transmission. This is a technical advantage compared to solutions with a prism.
The integrated stepper motor precisely selects any channel in less than one second. As opposed to solutions with piezo motors, high-quality optics are used to switch the channels and prevent frequency shifts. This high precision and repeatability of the switches lead overall to a high transmission and reproducibility of the optical signals.
The structural separation of adjacent channels prevents interference of the measurement signal by so-called crosstalk and ensures undistorted signals. This ensures interference-free signal transmission at full capacity.
Product features that prove convincing in use
The equipment of the multiplexer can be adapted in a modular way according to your actual needs and can be extended flexibly as well as economically at any time.
The basic version is designed for a total of 10 channels and offers 3 pre-installed channels as preparation for connection to the measuring points. Additional channels are freely selectable during product choice in the configurator.
The multiplexer is equipped by default with the feature bidirectional and can switch both transmitted and received signals simultaneously. A unidirectional model is also available.
You also benefit from an accessory set matched to the »Multiplexer FMX« , included in the scope of delivery by default.
The accessory set enables easy integration into the production line, supports maintenance and provides additional safety in the application.
With the help of a mounting plate with drawer extension, the installation of the FMX in a 19" rack is facilitated. The fiber optic cables can also be securely and easily attached here.
A strain relief provides additional mechanical protection for the connected optical fibers.
With the USB converter cable, the FMX can be easily connected to a PC via a serial interface.
A software module (SIMFMX01) for manual control via a PC is available free of charge on request. With the display and control function, test measurements and maintenance of individual measuring points for instance can be carried out easily and in a time-saving manner.
In the accessory section of the Hellma Product Configurator, you can configure your individual multiplexer version according to your needs.
Hellma offers the largest selection of products worldwide and the highest level of expertise to support your online measurements from UV to IR. Find the right measuring interface quickly and easily or configure your individual immersion probe or measurement cell.
