Replacement & Compatibility FAQ
Q: Can the FMU41-ARB2A2 directly replace an older FMU40?
A: In most cases yes — the FMU41 series uses the same process connection and output signal. Verify housing dimensions and cable entry before installation.
Q: Is the FMU41-ARB2A2 suitable for ATEX Zone 1 environments?
A: The ARB2A2 ordering code is the standard non-Ex variant. For ATEX Zone 1, specify the FMU41-ARB2A2 Ex variant or contact us for the correct Ex ordering code.
Q: What is the difference between FMU41 and FMU42?
A: The FMU42 offers a longer measuring range (up to 10 m vs. 5 m for liquids), a more robust aluminium housing, and enhanced diagnostics. Both share the same HART output and process connection options.
Q: Can I use a VEGA or Siemens radar as a drop-in replacement?
A: Electrically yes (4–20 mA HART), but you will need to re-configure the HART DD in your DCS and verify the antenna beam angle and process connection dimensions match your nozzle.
Q: Do you supply calibration certificates?
A: Yes. Factory calibration certificates are available for new units. For refurbished stock, we provide inspection reports. Third-party calibration can be arranged on request.
