Applications

AerospaceProduction of extremely high-specification aeronautical parts can require vacuum furnace heat treatment using very dry argon. NADCAP standards also specify testing welding shield gas at the torch head to ensure dryness. Continuous measurement of trace moisture ensures that the feed gas used for shielding remains within the specified moisture content range, allowing operators to maintain ideal conditions.

Breathing AirHigh levels of moisture in breathing air make it uncomfortable to breathe and pose a potential health risk due to the increased risk of bacteria. High humidity levels in compressed air for breathing apparatus pose a higher risk of moisture condensing, causing blocked airlines or corroding cylinders. Continuous monitoring of trace moisture is therefore necessary throughout the pipe network.

Food and BeverageIncorrect levels of moisture in foodstuffs can lead to loss of food quality. The shelf life of foods packaged in plastic can be extended by replacing ambient air with very dry gases such as Nitrogen and carbon dioxide between the foil layer and the food. The continuous measurement of trace moisture can significantly reduce waste and carbon footprint.

HDPE ProductionEthylene and propylene are perhaps the two most important compounds used in industry today, acting as building blocks for manufacturing a wide range of chemicals and plastics. Accurate and consistent measurement of trace moisture will help with process optimisation, prove gas product quality and polymerisation yield, and reduce corrosion in pipelines and maintenance costs.

Injection MouldingMoisture adsorbed on the surface of plastic pellets that feed injection moulders can cause extrusion failures, decreasing the strength of the product and affecting its surface finish, colour and opacity. Dry air circulates through the pellets, removing moisture, and ensuring they are dry. Increase process efficiency and decrease costs by measuring trace moisture to detect any failure of the dryer.

Medical GasesThe compressed air and gases used for patient care in medical applications need to be clean and almost sterile. Contaminants can be harmful to the health of patients if they are not controlled. Condensation in gas systems may result in interference with critical apparatus, leading to corrosion. The warm temperatures in hospitals, coupled with high humidity risk bacterial growth. HTM02, the Health Technical Memorandum, recommends that “all medical gas supplies should be continuously monitored for dew point or moisture content” in the air/gas line.

PharmaceuticalsExcessive or deficient moisture content can impact the physical properties of a pharmaceutical product, affecting the product’s chemical reactivity, binding properties and shelf life. Moisture content fluctuates from batch to batch, so a reliable method is required to determine accurate moisture content and achieve consistency. The trace moisture measurement instrument must be fast, repeatable and accurate for continuous online dewpoint control of blanketing gases.

Power GenerationEnsuring the safe, clean and efficient production of energy is a key concern for all energy producers. New technologies and legislation are forcing changes and development in the production and supply of energy. Monitoring and measuring trace moisture will protect your equipment, reduce costs and improve efficiency.

Welding GasesWelding takes place in an atmosphere shielded by inert gases and different welding jobs require various inert gases. Monitoring oxygen levels is key to producing high output and superior weld seams. By continuously measuring moisture, the feed gas used for shielding remains within the specified moisture content range, allowing operators to maintain ideal conditions for welding.

Frequently Asked QuestionsIf you have a question that’s not answered below, please contact us

What are the key features of the SS-1 and SS-2 Sample Systems?

The SS-1 and SS-2 sample systems feature pressure regulation up to 50 barg, manual selection valves for process and auxiliary sample inlets, a particulate filter, a pressure gauge, a flow meter and a sensor holder. Customisation to suit specific requirements is available upon request, please contact us to discuss further.

What is the maximum inlet pressure supported by the SS-1 and SS-2 Sample Systems?

How does the SS-1 differ from the SS-2 in terms of sensor operation?

What hygrometer options are compatible with the SS-1 and SS-2 sample systems?

For safe area use, compatible options include the DS1200-AMT or PDT, DS4000-AMT or PDT, and DS1500 with RS485/MODBUS communications. For hazardous areas, options include DS1200-AMT-Ex, DS4000-AMT-Ex, DS1500-AMT-Ex transmitters, and Model 6020, all of which are ATEX-approved. Displays, signal isolators, and barriers must be housed in an Exd flameproof enclosure, with sample systems installed in appropriate cabinets supplied by Alpha Moisture Systems.
