Summary of Application Scheme for Easidew IS Intrinsic Safety Dew Point Transmitter (EA2-IS-TX)

This article is a core summary of the application scheme of Easidew IS intrinsic safety dew point transmitter (EA2-IS-TX), integrating equipment core parameters, applicable scenarios, selection points, typical configurations, and industry practice effects, highlighting its essential safety core advantages, which can be directly used for project reports, equipment selection filing, and technical disclosure references.

一、Core parameters of equipment (key technical indicators)

二、Core applicable industries and scenarios

• Oil and gas industry: natural gas processing/transportation, LNG production, CNG drying, pipeline drying and gas handover measurement, monitoring of humidity in refining process media (anti icing, anti-corrosion, standard protection)

• Chemical industry: polymer (PE/PP/PET) production, petrochemical process liquids, special gas humidity measurement, catalyst protection (precise control of moisture, protection of catalyst activity, stable product quality)

• Energy sector: Hydrogen energy (hydrogen production/refueling stations), industrial heat treatment inert gas protection, can warn of pipeline stress corrosion risk (SCC) in H ₂ S environment, ensuring equipment safety

• General scenarios: Industrial gas dryer outlet monitoring, high-pressure switch protection gas micro water measurement, continuous online monitoring of trace water in various Zone 0/1 hazardous areas, suitable for OEM and system integration requirements

三、Key points of selection

1. Range matching: Priority is given to using the standard range of -110 ℃~+20 ℃ dp, and attention is paid to accuracy differences based on the measurement temperature range, covering the vast majority of industrial trace water measurement scenarios

2. Output selection: Based on on-site monitoring requirements, relying on a 2-wire 4-20mA output to achieve basic monitoring. If a fault warning function is required, alarm parameters can be configured in advance

3. Intrinsic safety adaptation: Based on the hazardous zone level on site (with a focus on Zone 0/1 adaptation), confirm the corresponding intrinsic safety certification (ATEX/IECEx/FM, etc.) for the equipment, and use it in conjunction with compliant safety barriers

4. Medium adaptation: Select the corresponding material configuration based on the measuring medium (gas/liquid, corrosiveness, temperature), and complete pipeline cleaning in advance for oxygen environment measurement

四、Typical configuration and practical effect

（一）Typical configuration scheme

Basic configuration: Easidew IS intrinsic safety dew point transmitter (EA2-IS-TX)+safety barrier+pre-processing system (filtering ≤ 80 μ m, pressure reduction ≤ 20 bar, constant temperature 20~50 ℃)+signal transmission module (compatible with DCS/PLC access)

Special configuration: Add high-voltage adapter joints for high-voltage scenarios; Add ultra clean pretreatment components to electronic chemical/high-purity gas scenarios; Oxygen measurement scene matching pipeline cleaning kit

（二）Core Case Effect

• Natural gas pipeline drying monitoring: adapted to Zone 1 hazardous area and high-pressure 100bar working conditions, with stable measurement accuracy, successfully warning of pipeline moisture infiltration trend, and avoiding stress corrosion leakage risk

• Polyethylene production: The water content of propylene raw materials is stably controlled at ≤ 1ppm (v), relying on precise measurement to protect catalyst activity, effectively extending catalyst service life, and reducing product defect rate

• Gas quality control of hydrogen refueling station: adapted to high pressure of 350/700bar, stable dew point control of hydrogen at ≤ -40 ℃ dp, in compliance with GB/T 37244 standard, intrinsically safe design ensures safe operation in hazardous hydrogen environments

五、Summary of Core Values

The Easidew IS intrinsically safe dew point transmitter (EA2-IS-TX), with its core advantages of intrinsic safety, high precision, high voltage resistance, and easy integration, relies on the patented ceramic metal oxide sensing technology of Micrel. It can be directly installed in explosion risk core areas such as Zone 0/1, effectively solving the pain points of trace water measurement in industrial hazardous environments, achieving production safety assurance, product quality improvement, and reduced operation and maintenance costs. It is suitable for global multi industry compliance requirements and is the preferred benchmark equipment for industrial intrinsically safe trace water measurement, especially suitable for harsh process scenarios with high requirements for installation convenience and safety level.
