Replacement & Compatibility FAQ
Q: Can the HONEYWELL STT850 directly replace the FC98-NX FC-20X SB2Z?
A: In most cases yes — both use 4–20 mA HART output and support TC/RTD inputs. However, verify the enclosure type and hazardous area certification match your installation requirements.
Q: Is the FC98-NX FC-20X SB2Z still in production?
A: HONEYWELL periodically updates its transmitter portfolio. Contact us to confirm current production status and available stock.
Q: Can I use a Rosemount 3144P as a drop-in replacement?
A: Functionally compatible for most HART 4–20 mA applications. Physical mounting dimensions differ — an adapter bracket may be required.
Q: Do you provide calibration certificates?
A: Yes. Factory calibration certificates are available. Third-party NIST-traceable calibration can be arranged on request.
Q: What is the warranty on this unit?
A: Konmask.com provides a 12-month warranty against manufacturing defects on all genuine units.
