Product Details

1. Product Overview

The Rosemount (Emerson) 42714098-V16-1 is an Infrared Detector (IR Detector), component ID GPN 350 I 39, serving as the core detection spare part for the NDIR (Non-Dispersive Infrared) measurement channel in Rosemount X-STREAM series continuous gas analyzers. It detects the absorption of specific wavelength infrared light by the gas sample to calculate gas concentration.

This infrared detector uses pyroelectric infrared sensing technology and is a key component in the analyzer's IR Photometer assembly. In an NDIR gas analysis system, broadband infrared light from the IR source passes through the gas sample cell; specific wavelength infrared light is absorbed by target gas molecules, and the remaining infrared light reaches the IR detector. The detector converts the light signal to an electrical signal, which is amplified by a preamplifier and transmitted to the analyzer mainboard for signal processing and concentration calculation.

The 42714098-V16-1 typically integrates an infrared sensing element, narrowband interference filter (for specific gas characteristic absorption wavelength), and preamplifier circuit as a plug-and-play detection module. Different versions (V16-1, V31, etc.) may correspond to different detected gas types and wavelength configurations, such as CO (carbon monoxide), CO2 (carbon dioxide), CH4 (methane), SO2 (sulfur dioxide), NO (nitric oxide), NO2 (nitrogen dioxide), N2O (nitrous oxide), HC (hydrocarbons), and other gases with characteristic infrared absorption wavelengths.

This product weighs approximately 160 grams, with a compact structure, installed in the analyzer's IR photometer assembly, typically connected to the analyzer mainboard through a dedicated interface. As a core spare part of the gas analyzer, the performance of the infrared detector directly affects the analyzer's measurement accuracy, stability, and response speed. After long-term use, the IR detector may experience sensitivity decline, zero drift, and reduced signal-to-noise ratio, requiring periodic replacement to maintain analyzer measurement performance.

Rosemount is a leading global process measurement and analytical instrument brand under Emerson. Its X-STREAM series continuous gas analyzers are widely used in petrochemical, natural gas, power, metallurgy, cement, and environmental emission monitoring (CEMS) industries, capable of measuring multiple gas components. The 42714098-V16-1 infrared detector, as a key spare part of this analyzer series, has broad applications in industrial process gas analysis and environmental emission monitoring worldwide.

Note: This product is a dedicated spare part for gas analyzers. Specific detected gas type, wavelength configuration, electrical interface, and other parameters need to be confirmed based on the analyzer model and configuration. Some parameters are marked "To be confirmed by manufacturer."

Mainly used in Rosemount X-STREAM series continuous gas analyzers NDIR measurement channels, including X-STREAM Enhanced XEGK (compact), XEGP (general purpose), XEFD (flameproof), XEXF, etc. The IR detector is installed in the analyzer's IR Photometer assembly as the core terminal receiving component in the optical path.

What gas? NDIR technology can detect multiple gases with infrared absorption characteristics. Different versions (V16, V31, etc.) correspond to different detected gases and wavelength configurations, possibly including CO, CO2, CH4, SO2, NO, NO2, N2O, HC, etc.

Note: The specific gas and wavelength for V16-1 needs to be confirmed based on your analyzer model, configuration, and the existing old detector label. Please provide the complete analyzer model and configuration code, or a photo of the old detector label, and we can help identify the specific gas type. If uncertain, marked "To be confirmed by manufacturer," subject to official Emerson confirmation.

Q2: What are the symptoms of a failed IR detector? How to judge replacement need? How often to replace?

A: The IR detector is the core component of an NDIR gas analyzer. After long-term use, it will age and performance decline. Common failure symptoms and replacement criteria:

Common symptoms of failed/aging IR detector:

Abnormally low or no measurement response when passing known concentration span gas
Severe zero drift, unstable zero when passing zero gas (high purity nitrogen), cannot recover via auto zero
Span drift / poor linearity, span calibration goes out of tolerance shortly after calibration
Reduced SNR / increased noise, measurement value jumping, especially obvious at low concentration
Slow response, T90 response time significantly longer than specification
Analyzer alarms: "detector fault", "optical path fault", "weak signal" (refer to analyzer manual for specific alarm codes)
Calibration cannot pass, zero/span calibration fails or calibration parameters exceed allowable range

How to judge replacement need?

Performance verification: Periodically pass standard gas for zero and span verification. If measurement error exceeds analyzer allowable range (usually ±2%FS or ±5%FS, refer to analyzer specs), and cannot recover after cleaning, calibration, adjustment — detector needs replacement.
Calibration trend analysis: Record zero and span parameters each calibration. If sensitivity (span gain) continuously declines, zero offset continuously increases — detector is aging, approaching replacement time.
SNR test: Professional maintenance personnel can measure detector output SNR via analyzer diagnostic function or oscilloscope. If SNR significantly below factory spec — detector aging.
Preventive replacement: Per analyzer maintenance manual recommended cycle, combined with actual operating environment (high temperature, high dust, corrosive gas accelerate aging), perform preventive replacement to avoid unplanned downtime.

How often to replace? Service life depends on multiple factors, no fixed cycle:

Good conditions (clean gas, constant temp, low concentration): 3-5+ years
General industrial process gas: 2-4 years
Harsh conditions (high temp, high dust, high humidity, corrosive gas): 1-3 years
Environmental CEMS monitoring (continuous operation): 2-3 years (recommend preventive replacement)

Recommendation: Comprehensive performance verification every 6-12 months; establish calibration parameter trend records; for critical applications (environmental monitoring, safety interlock, quality control), recommend keeping a spare detector for timely replacement.

Q3: How to replace the IR detector? Is calibration needed after replacement? Can I do it myself?

A: IR detector replacement requires certain professional knowledge and skills, recommended to be performed by trained professional maintenance personnel.

General replacement steps (refer to analyzer manual for specifics):

Preparation: Confirm analyzer stopped and powered off (or enter maintenance mode per manual); prepare new IR detector (confirm model/version match); prepare tools (screwdriver, hex wrench, anti-static wrist strap, lint-free cloth, isopropyl alcohol); record current analyzer calibration parameters (zero, span, calibration date).
Remove old detector: Open analyzer housing, locate IR Photometer assembly; disconnect detector electrical connection (plug/ribbon cable); loosen fixing screws/clips, carefully remove old detector. Note: the photometer assembly contains precision optical components (source, filters, sample cell), avoid collision and contamination.
Install new detector: Check new detector appearance and interface; align to installation position, gently push in until seated; tighten fixing screws/clips (moderate force, not over-tight); connect electrical plug/ribbon cable, confirm firm connection.
Close housing, power on warm up: Check no tools/foreign objects left inside; close analyzer housing; power on, let analyzer warm up and stabilize (usually 30 min to 2 hours, refer to manual).
Calibration verification: Pass zero gas (high purity nitrogen), perform zero calibration; pass span standard gas, perform span calibration; perform multi-point linearity verification if necessary; confirm measurement error within allowable range.

Is calibration needed after replacement? Must calibrate. After IR detector replacement, due to differences in sensitivity, zero, and spectral response between new and old detectors, zero and span calibration must be performed, and linearity calibration if necessary. Using without calibration will result in inaccurate measurements. Calibration standard gases must be Certified Reference Material (CRM) with accurate traceable concentration values covering the analyzer measurement range.

Can I do it myself?

If you or your maintenance personnel have received Rosemount gas analyzer maintenance training, are familiar with analyzer structure and calibration procedures, and have appropriate tools and standard gases — you can replace it yourself.
If no experience — recommend contacting Emerson official service or professional gas analyzer maintenance service provider for replacement and calibration, to avoid analyzer damage or inaccurate measurement from improper operation.
Notes: Wear anti-static wrist strap to avoid electrostatic damage to detector electronics; do not touch detector optical window (IR incident surface) with hands, if contaminated gently wipe with lint-free cloth dampened with isopropyl alcohol; avoid touching other optical components in the photometer during replacement; for flameproof analyzers (XEFD etc.), replacement must comply with explosion-proof regulations by qualified personnel.

Q4: What is the difference between V16-1 and V31? How to confirm which version my analyzer uses?

A: The 42714098 series IR detector has multiple versions (V16-1, V31, etc.), different versions correspond to different detected gas types and characteristic wavelength configurations, and are not interchangeable.

Difference between V16-1 and V31:

表格

Comparison	42714098-V16-1	42714098-V31
Base Part No.	42714098	42714098
Version	V16	V31
Detected Gas	To be confirmed (specific gas)	To be confirmed (another gas)
Wavelength	To be confirmed (gas absorption wavelength)	To be confirmed (different wavelength)
Filter Config	To be confirmed	To be confirmed
Interchangeable	No	No

The version number (V16, V31, etc.) is Rosemount's internal configuration code, corresponding to the narrowband interference filter wavelength built into the detector. Different gases have different characteristic infrared absorption wavelengths, requiring different detector versions. For example: CO ~4.65μm, CO2 ~4.26μm, CH4 ~3.43μm, SO2 ~7.3μm, NO ~5.3μm (reference wavelengths, subject to analyzer design).

How to confirm which version my analyzer uses?

Check old detector label: Most accurate method — check the label on the existing old detector inside the analyzer, the label will have the complete model (e.g., 42714098-V16-1) and component ID. Purchase per the old model.
Check analyzer spare parts list: Each Rosemount gas analyzer comes with a Spare Parts List, which lists the complete IR detector model and version.
Check analyzer model and configuration code: The complete analyzer model (e.g., XEGK-...) and configuration code contain measured gas type information, from which the corresponding detector version can be inferred, but requires Emerson official configuration table for confirmation.
Contact Emerson official: Provide complete analyzer model, serial number, and measured gas type, contact Emerson technical support or official service to confirm the corresponding IR detector model and version.
Provide old detector photo: If unsure, take a photo of the old detector label, we can help identify the model and version.

Important: Different version IR detectors cannot be mixed. Using the wrong version will result in completely inaccurate or no response measurement. If your analyzer has multiple NDIR measurement channels (multi-component analysis), each channel may use a different version detector, requiring separate confirmation. When purchasing, always provide the complete model including version number (V16-1), not just the base number 42714098.

Q5: In stock? Lead time? Price?

A: Currently Order Available. The 42714098-V16-1 is a dedicated IR detector spare part for Rosemount gas analyzers, a professional analytical instrument spare part with limited market inventory, specific stock fluctuates.

Lead time: Standard 4-8 weeks (ordering from Emerson through professional channels or global stock allocation). Dedicated gas analyzer spare parts usually need to be allocated from Emerson factory or regional spare parts centers, lead time relatively longer than standard instruments. Some common versions may be in stock, specific subject to formal quotation.
Price: Subject to formal quotation, depends on quantity, supply channel, whether includes technical service and calibration support. As a core optical electronic spare part for gas analyzers, it is a medium-to-high value spare part; bulk procurement enjoys tiered discounts.
