Honeywell SPXCDASMTXF Sensepoint XCD IR Flammable
Description
Overview
The Honeywell SPXCDASMTXF XCD transmitter is the 316 stainless steel version of the Sensepoint XCD configured as an infrared flammable (IR) gas transmitter without sensor, supplied with a 4-20 mA output and ATEX/IECEx Asian approvals. It is the corrosion-resistant transmitter for hydrocarbon gas detection in offshore and harsh process environments.
The transmitter is typically installed at the gas detection point with the sensing element fitted in the sensor housing, while the two programmable relays can drive local alarm beacons or shut down ventilation directly. Because every letter of the part number is significant in the Honeywell ordering scheme, this 316SS transmitter variant is frequently specified in material compatibility reviews for sour service.
The IR flammable configuration of the Sensepoint XCD detects hydrocarbon gases in the range 0-100% LEL using an infrared sensor, which provides fast response and long service life with minimal drift. The stainless steel housing makes this variant the first choice for marine, offshore and aggressive chemical atmospheres.
Engineering & Design
The Sensepoint XCD transmitter platform combines a local tri-colour backlit LCD, non-intrusive magnetic switch configuration and a 4-20 mA output (sink or source). This Honeywell SPXCDASMTXF XCD variant is supplied without sensor, so the correct IR flammable sensor can be fitted on site or the transmitter can be integrated into a system that already has sensor stock.
Infrared detection offers distinct advantages for hydrocarbon service: no poisoning by silicone or sulphur compounds, no oxygen requirement for the measurement, and a sensor element that typically lasts longer than catalytic alternatives before replacement. The IR sensor measures the absorption of infrared energy by the hydrocarbon gas and reports the result as percent LEL, which makes this transmitter configuration a strong choice for continuous monitoring of methane and other alkanes in process areas.
The 316 stainless steel housing has 2 x M20 cable/conduit entries and is rated IP66. Two programmable alarm relays and one fault relay are standard, and an optional MODBUS output provides remote diagnostics. The certified temperature range is -40 °C to +75 °C.

Ordering Information
Order the Honeywell SPXCDASMTXF XCD transmitter for a stainless steel IR flammable gas detection point. Because this unit ships without sensor, confirm the required sensor part number with our team when ordering.
The Sensepoint XCD IR transmitter uses the infrared sensor for the flammable gas detection, and the detector is certified for the hazardous area installations.
Why Seven Star LLC
Seven Star LLC supplies Honeywell gas detection spares to offshore and onshore plants across Oman and the GCC. This transmitter is supplied as a transmitter-only unit, with the sensor ordered separately.
Our engineers help you verify the exact model and revision before ordering, avoiding costly mismatches.

Submit a formal inquiry through our RFQ page with your configuration and application details, and our specialists will respond with a detailed commercial proposal and the Honeywell product documentation.
Confirming the Part Number and Sensor
In the Sensepoint XCD ordering scheme each character of the code defines part of the build, such as housing material, sensor type and approvals. When replacing a unit, read the full code from the transmitter label and compare it with the original order rather than relying on the tag description alone. Because this variant ships without a sensor, also record the part number of the IR flammable sensor currently installed, or the one specified for the detection point, so that transmitter and sensor are ordered as a matched pair.
Installation and Commissioning
- Mount the detector where the target gas is likely to accumulate, taking gas density, ventilation and potential leak sources into account
- Use certified cable glands or conduit fittings suitable for the hazardous area classification on the M20 entries, and close any unused entry with a certified plug
- Fit the sensor, power up and allow the recommended warm-up time before calibration
- Carry out zero and span calibration with the correct test gas using the magnetic switch interface
- Check the 4-20 mA signal, both alarm relays and the fault relay with the fire and gas system
Maintenance and Troubleshooting
Infrared sensors are not poisoned in the way catalytic sensors can be, but regular bump tests and calibration checks are still required under most site procedures. Dirt, insects or water on the sensor optics can cause fault indications or reduced response, so the weather protection and sensor inlet should be inspected during routine rounds. A fault relay alarm should be investigated using the transmitter display and fault codes before the sensor is replaced. The 316 stainless steel housing resists corrosion well, but cable glands and seals should still be checked, particularly on offshore and coastal installations.
Gas Detection in Oman and the GCC
Coastal plants, offshore platforms and terminals in the region combine salt-laden air with high temperatures, which is where a stainless steel housing gives a clear service-life advantage. Typical locations include compressor houses, pump areas, loading facilities and process modules.

About brand
Honeywell is the American industrial technology group whose products on this site cover gas and flame detection, pressure transmitters, flow measurement, gas metering, fire alarm systems and helicopter rotor balancing equipment. Its roots go back to a thermostat business in Minneapolis in 1885 and to Mark Honeywell's heating company, which merged with it in 1927. Several brands we list have joined Honeywell over the years: Gent fire systems of Leicester (part of Honeywell since 2005), Chadwick-Helmuth (a Honeywell business unit from 2002) and Elster gas metering (acquired around the end of 2015).
Seven Star LLC is an independent supplier in Muscat. We list Honeywell gas detectors and sensors, transmitters, Elster gas meters and flow computers, Gent fire alarm equipment and Chadwick-Helmuth balancers, and supply them and their spares in Oman and the GCC by part number.

Gas detection uses two basic approaches. Point detectors such as the Sensepoint XCD measure the gas at one location, with a catalytic or infrared sensor for flammable gas and an electrochemical cell for toxic gas such as H2S. Open path detectors such as the Searchline Excel send an infrared beam across an area up to a few hundred metres long and detect a gas cloud anywhere along it. Infrared sensors cannot be poisoned the way catalytic beads can, which matters on sites with silicones or H2S.
Where Honeywell products are used
In Oman and the GCC, Honeywell gas detectors protect wellheads, gas plants, refineries and tank farms. Elster meters and flow computers measure gas at city gate stations and in industry. Gent systems are installed in commercial buildings, hospitals and hotels, and Chadwick-Helmuth balancers are used by helicopter operators.
Ordering Honeywell products: what we need
Send the part number from the label (for example 02104-N-XSSA or SPXCDASMTXF). For gas detectors, add the gas, range, output and certification. For gas meters, add size (DN), flow range and pressure rating. For Gent equipment, add the panel type and loop protocol.
