LCMC - weighing chain
Load Cell Measurement Chain (LCMC) - intelligent customizable measurement chain
Create a customized LCMC digital weighing chain by optionally combining established HBK load cells with your preferred interface to meet your specific needs and get a preset measurement chain without the need for additional special knowledge to set it up.
The weighing chain (LCMC) is a combination of your chosen HBK weight sensor and an electronic amplifier with the desired output.
LCMC includes a choice of one of 14 available HBK load cells to suit your requirements, combined with a common electronic unit. While the amplifier is the same for all 14 load cells, it provides seven different output options, including IO-Link compatibility.
With the potential for 11,000 unique configurations, this standardized solution not only offers superior performance and cost-effectiveness, but also ensures precise customization to your needs.
The IO-Link interface brings several advantages such as intelligent functions (data pre-processing, self-monitoring and warning), bidirectional sensor communication and easy installation.
LCMC with IO-Link interface
IO-Link technology offers you fast measurement, lower costs, greater efficiency and reliability. Below you will find an overview of the digital functions.
- Output signal - Digital signal according to IO-Link standard, baud rate COM 3.
- Filtration - Up to 5 filter stages can be used: FIR, IIR, comb filter or moving average.
- Clever algorithms - The device integrates algorithms for filling and checkweighing.
- Sensor status monitoring - Self-monitoring of sensor-specific limit values and triggering of an IO-Link event if an exceedance is detected.
- Scaling - Two-point scaling manually or by user setting (calibration process).
- Statistics - Maximum, minimum, peak-to-peak, run-time counter, over-limit counter.
- Limit switch - Two limit switches.
- Digital output - One permanently available digital IO. A second digital IO is available if IO-Link transmission is deactivated
- Units - Load cells measure load in kilograms. Switching of units and change of scale is possible as required.
