Selection and Procurement Recommendations

When purchasing FMU44 spare parts, be sure to check the order number and applicable models to ensure compatibility. For hazardous areas, electronic modules with the Ex marking should be selected. Seal kits and O-rings must be selected with suitable materials (such as EPDM) according to the process medium and temperature.

  • Confirm that the device model matches the applicable model of the spare part.
  • Pay attention to explosion-proof certification requirements and select the corresponding version of the electronic module.
  • Seal material must be compatible with the process medium.
  • The mounting bracket material (such as 316Ti) must meet the environmental corrosion requirements.

Frequently Asked Questions (FAQ)

How do I determine the order number of the required spare part?

You can find the corresponding order number in this document based on the device model and the name of the required component. If uncertain, it is recommended to contact Endress+Hauser technical support.

Are FMU44 spare parts suitable for other models?

Some spare parts are universal, but electronic modules and sensors usually have specific applicable models. Please check carefully.

What should be noted when selecting spare parts for hazardous areas?

Spare parts with the corresponding explosion-proof certification must be selected, such as Ex version electronic modules, and ensure compliance with on-site safety regulations.
