SPXCDALMFX vs SPXCDALMTXT: Which Honeywell XCD Model Do You Need?

Choosing between Honeywell SPXCDALMFX and SPXCDALMTXT can be confusing because both part numbers belong to the Sensepoint XCD gas detection family and share a similar enclosure design.

However, they are not different packaging versions of the same product.

SPXCDALMFX is a combustible gas detector with a catalytic bead sensor, while SPXCDALMTXT is a transmitter intended for use with a separately selected toxic gas or oxygen sensor.

HKXY has prepared this comparison to help purchasing teams, maintenance engineers and gas detection system integrators identify the correct model before requesting a quotation.

Quick Comparison

SPXCDALMFX

• Product type: Complete fixed combustible gas detector

• Detection category: Flammable gas

• Sensor technology: Catalytic bead

• Typical gas: Methane

• Typical range: 0–100% LEL

• Sensor supplied: Yes, according to the specified configuration

• Enclosure: Painted LM25 marine-grade aluminum

• Cable entry: M20

• Typical buyer: Facilities monitoring combustible gas hazards

SPXCDALMTXT

• Product type: Sensepoint XCD transmitter

• Detection category: Toxic gas or oxygen

• Sensor technology: Determined by the separately selected sensor

• Target gas: Determined by the connected sensor

• Measuring range: Determined by the connected sensor

• Sensor supplied: Normally no

• Enclosure: Painted LM25 marine-grade aluminum

• Cable entries: 2 × M20

• Typical buyer: Customers replacing or configuring an XCD toxic gas or oxygen detector

The most important difference is simple:

Choose SPXCDALMFX for combustible gas detection.

Choose SPXCDALMTXT when you need an XCD transmitter for a compatible toxic gas or oxygen sensor.

What Is Honeywell SPXCDALMFX?

Honeywell SPXCDALMFX is a Sensepoint XCD fixed gas detector designed for combustible gas monitoring in industrial environments.

The model is commonly identified as a catalytic bead detector for methane measurement over a 0–100% LEL range. It combines gas sensing, local indication and signal transmission in a field-mounted industrial enclosure.

Typical applications include:

• Oil and gas facilities

• Refineries

• Petrochemical plants

• Fuel storage areas

• Boiler rooms

• Compressor rooms

• Power generation facilities

• Industrial manufacturing sites

The Sensepoint XCD platform provides a tri-color local display, a 4–20 mA signal and Modbus communication for connection to compatible plant monitoring and control systems.

SPXCDALMFX may be the appropriate choice when a project specification calls for:

• A fixed combustible gas detector

• Catalytic bead sensing technology

• Methane detection

• A 0–100% LEL measuring range

• An LM25 aluminum enclosure

• M20 cable entry

• Sensepoint XCD system compatibility

The complete part number, certification and gas configuration should always be verified before ordering.

What Is Honeywell SPXCDALMTXT?

Honeywell SPXCDALMTXT is a Sensepoint XCD transmitter used as part of a toxic gas or oxygen detection configuration.

Unlike SPXCDALMFX, SPXCDALMTXT should not normally be treated as a complete gas detector with an included sensor. A compatible sensor must be selected according to the gas that needs to be monitored.

Depending on the approved Honeywell configuration, Sensepoint XCD toxic and oxygen applications may include:

• Hydrogen sulfide

• Carbon monoxide

• Oxygen

• Hydrogen

• Ammonia

• Chlorine

• Sulfur dioxide

• Other supported toxic gases

The connected sensor determines the target gas and measuring range. Therefore, ordering SPXCDALMTXT without confirming the sensor requirement can result in an incomplete or incompatible system.

SPXCDALMTXT may be the appropriate choice when:

• An existing XCD toxic/oxygen transmitter needs replacement

• The compatible gas sensor is already installed or ordered separately

• A new toxic gas or oxygen monitoring point is being configured

• The project specifies an LM25 enclosure with M20 entries

• 4–20 mA and Modbus communication are required

Which Model Should You Buy?

Choose SPXCDALMFX if you need to monitor a combustible gas and your specification requires a catalytic bead Sensepoint XCD detector.

Choose SPXCDALMTXT if you need a transmitter for a compatible toxic gas or oxygen sensor.

Do not choose based only on enclosure appearance. The sensor type, target gas, measuring range, certification and cable-entry configuration must all match the application.

Before requesting a quote, check the following information:

1. Target gas

Confirm whether the application involves a combustible gas, toxic gas or oxygen.

2. Measuring range

For combustible gases, the range may be expressed as a percentage of the Lower Explosive Limit. Toxic gas ranges are commonly expressed in ppm, while oxygen is normally expressed as a percentage by volume.

3. Complete part number

A single character in a Honeywell part number may represent a different sensor, enclosure, entry or certification.

4. Sensor requirement

SPXCDALMTXT normally requires a separately selected compatible sensor. State clearly whether you need the transmitter only or a complete detector configuration.

5. Certification

Confirm the hazardous-area and regional certification required by the installation site.

6. Existing nameplate

For replacement orders, send a clear photograph of the existing transmitter and sensor nameplates. This is often the fastest way to identify the required configuration.
