MICHELL CD2-SX-WDC-002 Water Dew-Point Sensor Exchange for Condumax II

Overview

The MICHELL CD2-SX-WDC-002 Water Dew-Point Sensor Exchange is a fully calibrated replacement sensor cell designed for the Condumax II hydrocarbon and water dew-point analyzer, one of the natural gas industry’s most widely deployed continuous, automatic gas quality monitoring instruments. Rather than sending a sensor away for recalibration and waiting through extended turnaround times, the CD2-SX-WDC-002 exchange program supplies a pre-calibrated replacement sensor so that Condumax II analyzers can return to service almost immediately, minimizing downtime during routine maintenance.

As an authorized supplier of MICHELL Instruments, Seven Star LLC proudly supplies the CD2-SX-WDC-002 to natural gas transmission operators, custody transfer stations, and process gas facilities across the Sultanate of Oman, Muscat, and the wider GCC. Continuous, accurate water dew-point measurement is critical for pipeline integrity and compliance with custody transfer specifications, and this exchange sensor keeps that measurement chain uninterrupted.

Measurement Principle

The CD2-SX-WDC-002 sensor uses Michell’s Ceramic Metal-Oxide Moisture Sensor technology to provide water dew-point measurement within the Condumax II analyzer. The Condumax II itself uses the proven ‘Dark Spot’ direct chilled-mirror technique to measure hydrocarbon dew point with high accuracy and long-term reliability, and when fitted with the ceramic metal-oxide water dew-point sensor, the same instrument continuously and automatically tracks both critical parameters of natural gas quality side by side.

Each exchange sensor is supplied with its own Calibration Certificate, providing direct traceability to both UK (NPL) and US (NIST) Humidity Standards. This traceability ensures that measurements taken after the sensor exchange remain fully consistent with the metrology standards required for custody transfer and regulatory reporting in the natural gas sector.

Engineering Design

The CD2-SX-WDC-002 is engineered as a direct, fully calibrated exchange unit for the water dew-point sensor assembly within the Condumax II’s compact explosion-proof enclosure. Because the Condumax II is housed in an explosion-proof/flameproof enclosure suitable for installation in Zone 1 or 2 (Class I, Division 1 and 2) hazardous areas, the sensor exchange is designed to integrate seamlessly with this certified housing without compromising the instrument’s hazardous area rating.

The exchange program is structured specifically to reduce field maintenance time: rather than removing the sensor for off-site recalibration and reinstallation, operators receive an already-calibrated replacement sensor to install directly, with the removed sensor returned to Michell for its own recalibration cycle. This rotating exchange model is particularly valuable for remote pipeline stations and metering sites where technician visits and instrument downtime carry significant operational cost.

Key Features

The CD2-SX-WDC-002 delivers dependable sensor continuity for Condumax II analyzers. Core capabilities include:

• Fully calibrated water dew-point sensor exchange, minimizing instrument downtime during maintenance.
• Ceramic Metal-Oxide Moisture Sensor technology for accurate, stable water dew-point measurement.
• Supplied with its own Calibration Certificate, traceable to UK (NPL) and US (NIST) Humidity Standards.
• Purpose-built for direct compatibility with the Condumax II hydrocarbon and water dew-point analyzer.
• Compatible with Condumax II units used in natural gas containing up to 20% hydrogen.
• Supports continuous, automatic dual-parameter gas quality monitoring alongside hydrocarbon dew point.
• Genuine Michell Instruments part, ensuring full compatibility and warranty support.

Industrial Applications

The CD2-SX-WDC-002 sensor exchange is essential to natural gas transmission and distribution networks, custody transfer metering stations, and petrochemical processing facilities that rely on Condumax II analyzers for continuous gas quality assurance. Accurate water dew-point measurement prevents the formation of hydrates and liquid water in gas pipelines, protecting infrastructure integrity and ensuring compliance with pipeline specifications.

As an authorized supplier of MICHELL Instruments, Seven Star LLC distributes the CD2-SX-WDC-002 to oil and gas operators, LNG terminals, and gas processing plants throughout Oman and the broader GCC region, supporting the reliable, continuous operation of critical gas quality monitoring infrastructure across the region’s energy sector.
