Technical parameters:

High precision compressed air dew point meterApplication fields:

1. Quality control of compressed air system
Performance monitoring of dryer: installed at the outlet of the dryer, real-time monitoring of the dew point of compressed air to ensure the normal operation of the dryer (such as adsorption or refrigeration) and prevent excessive humidity caused by desiccant failure or insufficient cooling.
Pipeline humidity monitoring: Installed at multiple nodes of the compressed air distribution pipeline to avoid secondary moisture pollution caused by pipeline condensation or leakage.

2. Protection of critical industrial processes
Pneumatic equipment and control systems: Moisture can cause corrosion or icing of pneumatic valves, cylinders, and other equipment in low-temperature environments. Dew point monitoring can prevent equipment failure and extend service life.
Spray coating process: In scenarios such as automobile manufacturing and furniture spraying, high humidity can cause coating bubbles and peeling, and it is necessary to strictly control the dew point of compressed air (usually requiring dew point ≤ -40 ℃).
Electronic Manufacturing and Semiconductors: Clean and dry air is used for circuit board cleaning and chip packaging. Trace amounts of moisture may cause short circuits or oxidation, and the dew point should be kept below -70 ℃.

3. Food and drug production
Compressed air in direct contact with the product: During filling, packaging, mixing, and other processes, moisture may breed microorganisms or contaminate the product. It must comply with FDA, GMP and other standards (such as ISO 8573-1 standard), and dew point monitoring must ensure that the air quality meets the standards.
Aseptic environment control: The sterile workshop of the pharmaceutical factory needs to use ultra dry air to prevent drugs from getting damp and deteriorating.

4. Energy and Industrial Gases
Instrument air system: The instrument air used in power plants and chemical plants needs to be dry (dew point is often required to be ≤ -40 ℃) to avoid moisture causing instrument misoperation.
Gas storage and transportation: drying treatment of natural gas pipelines and industrial gases (nitrogen, oxygen) to prevent hydrate blockage or corrosion.

5. Energy saving and operation optimization
Adjust the drying system as needed: dynamically control the operation of the dryer based on real-time dew point data to avoid energy waste caused by excessive drying.
Fault warning and maintenance: Abnormal increase in dew point can indicate filter blockage, desiccant failure, or system leakage, assisting in preventive maintenance.

6. Special environmental applications
Low temperature and outdoor scenarios: such as refrigerated warehouses and polar equipment, monitoring dew points to prevent moisture in compressed air from freezing and blocking pipelines.
Breathing air system: Compressed air used for firefighting and diving must comply with safety dew point standards (such as NFPA 1989) to avoid freezing or discomfort during breathing.

Technical selection precautions
Measurement range: Select the appropriate range according to the requirements (such as -100 ℃ to+20 ℃ dew point).
Sensor types: capacitive (economical and durable), cold mirror (high-precision), etc.
Environmental adaptability: Characteristics such as pressure resistance, oil pollution resistance, and explosion prevention need to be matched with on-site conditions.
Data integration: Supports 4-20mA, Modbus and other outputs, making it easy to connect to PLC or SCADA systems.
