SPXCDXSO1SS: replacement O2 sensor for Sensepoint XCD

The Honeywell SPXCDXSO1SS is a plug-in stainless-steel oxygen sensor cartridge for compatible Sensepoint XCD transmitters. Honeywell identifies this model as an oxygen sensor with a 25.0% by volume range. It is a sensor-only replacement part, not a complete wall-mounted transmitter.

This distinction matters during procurement. Buyers replacing only the sensing element should request SPXCDXSO1SS; projects requiring a complete detector must specify the appropriate Sensepoint XCD transmitter-and-sensor assembly, enclosure, cable entry and approval configuration.

Exact-model identification

Why maintenance teams use the XCD cartridge design

Honeywell offers the Sensepoint XCD transmitter and sensor separately for maintenance programs and larger projects. The cartridge plugs into the socket at the bottom of a compatible transmitter. According to Honeywell, the transmitter recognizes the installed sensor type and configures itself accordingly, helping reduce replacement complexity.

Automatic recognition does not remove the need for commissioning checks. After installation, Honeywell instructs users to perform a bump or gassing test to validate the function of the complete XCD assembly. Work should be completed by qualified personnel in accordance with the current technical manual, site permit requirements and local gas-safety procedures.

Typical replacement situations

• Scheduled oxygen-sensor replacement in an existing Sensepoint XCD installation.

• Maintenance stock for plants using standardized XCD transmitters.

• Restoring a detector after diagnostics confirm that the cartridge requires replacement.

• Separately staged sensor procurement where limited sensor shelf life affects project timing.

Compatibility checks before ordering

Do not select a sensor cartridge by appearance alone. Confirm the existing transmitter family, full cartridge part number, target gas and range. A photo of the original cartridge label and transmitter nameplate helps prevent confusion with other Sensepoint XCD replacement sensors for H₂S, CO, hydrogen, NO₂, combustible gases or CO₂.
