Process Instrumentation / Analyzer Systems / Weighing Technology / Valve Positioner / MI Digital Solution: Siwarex Ms

Can someone please confirm if it is acceptable to use other LOAD CELLS than those provided by SIEMENS, for the SIWAREX MS module?
Are there any special calibration I have to follow, in both cases?

Using Third-Party Load Cells with SIWAREX MS

Yes, you can use load cells from manufacturers other than Siemens with the SIWAREX MS module. However, ensure the load cell meets the required specifications for your application and is compatible with the SIWAREX MS signal input.

Calibration Considerations:

Siemens Load Cells: Typically, Siemens load cells come pre-calibrated or have calibration data readily available for easy integration with SIWAREX MS via the software tools.

Third-Party Load Cells: Crucially, you'll need to perform a thorough calibration. This involves:

  • Initial Calibration: Establish the zero point and gain of the load cell within the SIWAREX MS.
  • Linearization: Create a linearization curve if the load cell exhibits non-linearity (highly recommended for accurate measurements).
  • Calibration Documentation: Keep detailed records of the calibration process, including weights used and calibration factors.

Refer to the SIWAREX MS manual ( SIWAREX MS Manual) for detailed calibration instructions. Also, review the load cell manufacturer’s documentation for specific calibration recommendations.

Important: Incorrect calibration can lead to inaccurate weighing results. If unsure, contact Siemens support or a qualified weighing equipment technician.
