Explosion proof compressed air dew point meter

Explosion proof compressed air dew point meterProduct Introduction

The water vapor content in natural gas can seriously affect its effectiveness. The presence of a large amount of water vapor can cause corrosion, condensation, and other problems in pipelines, valves, and other equipment. It may also mix with other gases to form flammable and explosive gases, seriously endangering safety. Therefore, accurately measuring the water vapor content in natural gas is very important.

A natural gas dew point meter is a specialized instrument used to measure the water vapor content in natural gas. It can determine the dew point temperature of natural gas at a specific pressure, that is, the temperature at which the gas is cooled to the point where water vapor begins to condense into liquid water. This measurement is crucial for ensuring the quality and safe transportation of natural gas, as excessive water vapor content may lead to pipeline corrosion, blockage, and reduced calorific value.

The FM300EX explosion-proof dew point meter adopts capacitive alumina silica mixed medium technology, which can measure trace moisture in gases. Even in harsh industrial environments, the dew point can be reliably determined. The FM300EX online explosion-proof dew point meter is a device used to detect the moisture content in flammable or ordinary gases, especially suitable for hazardous environments. It adopts the principle of online detection, which can monitor potential explosive gases in the air in real time and issue timely alarms to ensure on-site safety. The dew point measurement range of FM300EX is -110 ·····+20 ° Ctd, measurement accuracy: ± 2 ° C, repeatability: 0.5 ° C dew point, output signal: 4-20 mA current and RS485 communication, while measuring various data such as dew point ℃ td, temperature ℃, humidity% RH, micro water PPM, etc. Explosion proof rating: Ex db IIC T6 Gb.

Typical applications of dew point measurement:

Sipachi dew point meters are applied in the field of industrial dew point measurement with extremely low gas humidity. Dew point is usually a critical parameter, and inadequate control can lead to production downtime, damage to process equipment, and a decrease in product quality.

Dew point data needs to be measured in various drying and heat treatment processes. Dew point parameters should also be controlled in compressed air, as excessive humidity can lead to poor quality of end products, icing, and equipment corrosion. Other common applications include medical gases, dry environments for lithium battery production, and high-voltage gas insulated equipment used in the power industry.

Precautions for maintenance of dew point meter:

Regular calibration: Dew point meters may experience errors after long-term use, so regular calibration is necessary. The calibration frequency and method should be determined according to the instrument model and manufacturer's requirements.

Keep dry: The dew point meter should be kept dry before use to avoid affecting measurement accuracy. When not in use for a long time, the instrument should be placed in a dry environment to avoid the accumulation of moisture.

Cleaning: The dew point meter should be cleaned on the surface and sensor part before use to ensure measurement accuracy. Organic solvents or corrosive substances should be avoided during cleaning to prevent damage to the instrument.

Avoid vibration: The dew point meter should be protected from vibration or collision during use to avoid affecting measurement accuracy.

Handle with care: When transporting, handle with care and do not litter or collide

Storage: The storage environment should be kept dry, free of corrosive gases, and free from strong magnetic field interference.

Explosion proof: It has explosion-proof function and its grounding reliability should be ensured.

Maintenance: Regularly maintain and upkeep the instrument to maintain its good working condition.

Calibration cycle:

We calibrate once a year, and if calibration and debugging are required, they can be sent to Sipachi Shanghai Maintenance Center. Sipachi Shanghai has a dew point meter calibration enterprise.
