Frequently Asked Questions
What industrial applications require SHAW Instruments dewpoint meters?
SHAW Instruments dewpoint meters are critical for measuring trace moisture in compressed air systems, industrial gases, and petrochemical processing. Accurate moisture measurement is essential to prevent pipeline corrosion and ensure the quality of high-purity gas streams.
Are SHAW moisture sensors capable of operating in hazardous area environments?
Yes, SHAW Instruments offers intrinsically safe dewpoint transmitters that are ATEX and IECEx certified for use in hazardous zones. These robust sensors provide reliable continuous moisture monitoring in explosive atmospheres like oil refineries and chemical plants.
How does the auto-calibration feature of SHAW sensors benefit plant operations?
The unique Automatic Calibration (AutoCal) feature allows operators to verify and adjust the sensor span in the field without the need for complex reference gases. This drastically reduces maintenance downtime and ensures long-term measurement drift is easily managed.
Can SHAW Instruments portable dewpoint meters be used for spot-checking gas lines?
SHAW portable dewpoint meters are specifically engineered for rapid spot-checking, featuring rapid response times and integrated desiccant chambers that keep the sensor dry between tests. This allows engineers to instantly measure process lines and verify air dryer performance.
What makes the SHAW sensor technology highly resistant to chemical degradation?
The proprietary SHAW ultra-high capacitance sensor is constructed with a resilient gold and aluminum oxide composition that resists chemical attack and condensation. This durable engineering ensures exceptional longevity and stability even in challenging process gas environments.
