Compressed air dew point transmitter

Compressed air dew point transmitterProduct Introduction

The FM300 integrated on-site display dew point transmitter uses capacitive alumina silica mixed medium technology to measure trace amounts of moisture in gases. Even in harsh industrial environments, the dew point can be reliably determined.

• Integrated LCD display

• Can prevent condensation water

• Adopting a sturdy aluminum die-casting shell

The rated measurement range of FM300 is -110 ·····+20 ° Ctd, which can meet the dew point measurement needs of most industrial production. The shell is made of stainless steel material, which has high protection and corrosion resistance.

FM300 has excellent measurement stability, which can save you complex calibration costs. You can choose accessories for FM300 products according to your needs: stainless steel sampling chamber and stainless steel mounting base.

Display units can be switched: dew point ℃ td, temperature ℃, humidity% RH, micro water PPM, KJKg

Technical parameters:

Application fields:

1. Compressed air system:

Monitor the dew point at the outlet of the dryer to ensure that the compressed air quality meets the ISO 8573 standard.
2. Industrial gas production:

Control the humidity of gases such as nitrogen, oxygen, and hydrogen to prevent pipeline condensation or instrument failure.
3. Lithium battery manufacturing: Ensure extremely low humidity (dew point ≤ -40 ° C) in the drying room or glove box to improve battery performance.
4. Power industry:

Monitor SF6 gas humidity to prevent insulation performance degradation of high-voltage switchgear.
5. Food and Medicine:

Monitor the dew point of clean compressed air to prevent microbial growth or product moisture.

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.
