Michell CD2-WDC-002 Water Dew-Point Sensor Assembly
Overview
The Michell CD2-WDC-002 is a water dew-point sensor assembly engineered for Michell Instruments’ Condumax II hydrocarbon and water dew-point analyzer platform, a system widely deployed for continuous, automatic natural gas quality monitoring across gas processing, transmission, and custody-transfer applications. The sensor cell integrates a pressure transmitter with the Condumax II’s proven chilled-mirror measurement chamber, providing the direct water dew-point reading that operators need to protect downstream equipment from hydrate formation and condensation damage.
As the official authorized partner and exclusive regional representative for Michell in the Sultanate of Oman, Seven Star LLC proudly supplies the Michell CD2-WDC-002 sensor assembly with full manufacturer traceability and calibration documentation. Gas processing and transmission facilities across Muscat, Sohar, and Salalah rely on Seven Star LLC to source genuine Michell components, avoiding the measurement drift and unsupported hardware associated with unauthorized aftermarket sensor assemblies.
Measurement Principle
The Michell CD2-WDC-002 works within Michell’s field-proven “Dark Spot” direct chilled-mirror measurement principle, in which a precisely temperature-controlled mirror surface is cooled until condensation first begins to form on it, and an optical detection system identifies this exact onset point. The mirror temperature at which condensation first appears is, by definition, the water dew point of the sample gas, giving the Condumax II analyzer a direct, physically fundamental measurement rather than an inferred or model-based estimate.
Because the chilled-mirror technique measures the actual phase-change point of the sample rather than relying on a secondary correlation, it delivers long-term accuracy and reliability that other dew-point measurement technologies struggle to match over extended field service. The practical consequence for gas quality engineers is a dew-point reading they can trust for custody-transfer and hydrate-prevention decisions without the recurring recalibration burden associated with less direct measurement methods.
Engineering Design of the Michell CD2-WDC-002
The Michell CD2-WDC-002 combines the water dew-point sensor cell with an integrated pressure transmitter, allowing the Condumax II analyzer to reference dew-point readings against the actual sample pressure for accurate correction to standard reference conditions. This integrated pressure-referencing capability is essential for natural gas quality reporting, since dew point varies directly with operating pressure and must be normalized for consistent, comparable readings across changing pipeline conditions.
The sensor assembly is designed as a field-serviceable component of the broader Condumax II system, allowing maintenance teams to exchange the sensor cell during scheduled service without needing to replace the full analyzer chassis. This modular design philosophy reduces both the cost and downtime associated with maintaining accurate, continuous dew-point monitoring on critical gas quality measurement points.
Key Features
The Michell CD2-WDC-002 combines fundamental chilled-mirror measurement with practical field serviceability, and the following features summarize why gas quality engineers specify Condumax II sensor assemblies for critical monitoring points:
- Direct “Dark Spot” chilled-mirror measurement provides a physically fundamental dew-point reading rather than an inferred estimate.
- Integrated pressure transmitter allows accurate correction of dew-point readings to standard reference conditions.
- Field-serviceable modular design reduces maintenance downtime compared to full analyzer replacement.
- Long-term measurement stability minimizes recalibration frequency on continuous monitoring installations.
- Purpose-built for integration with the established Condumax II analyzer platform.
- Supports both hydrocarbon and water dew-point monitoring requirements in natural gas quality programs.
- Proven technology base with an established track record in custody-transfer gas quality applications.
- Genuine Michell manufacturing ensures consistent performance matched to the analyzer’s calibration.
Industrial Applications
The Michell CD2-WDC-002 supports continuous water dew-point monitoring at natural gas processing plants, pipeline custody-transfer metering stations, and gas transmission compressor stations where hydrate prevention and gas quality compliance depend on accurate, continuous measurement. In Oman, Condumax II-based dew-point monitoring is widely deployed across the country’s gas processing and export infrastructure to protect pipelines and downstream equipment from condensation and hydrate-related damage.
As the officially authorized partner for Michell, Seven Star LLC distributes genuine sensor assemblies and Condumax II components to gas processing operators and instrumentation contractors throughout the Sohar and Salalah economic zones, supporting both new analyzer commissioning and sensor cell replacement on existing installations across Muscat. Reliable dew-point measurement is a critical safeguard for the GCC’s natural gas transmission and processing infrastructure.

Why Choose Seven Star LLC for Michell Water Dew-Point Sensors
A dew-point sensor assembly’s measuring range and process connection have to be matched to your actual gas drying or moisture monitoring application, since a sensor calibrated for a very dry gas stream performs poorly at higher moisture levels, and vice versa. Seven Star LLC confirms the correct CD2-WDC-002 configuration against your specific application and process connection before order confirmation, drawing on our authorized Michell Instruments partnership across Oman and the wider GCC. We also support gas processing and compressed air facilities across Muscat, Sohar, and Salalah with recalibration scheduling and traceable certificate management, keeping moisture measurement points defensible for both process control and quality documentation purposes.
