Product Details
Compressed air dew point moisture detectorProduct Details:
The FM870 online dew point meter is a high-precision online monitoring device designed for real-time measurement of dew point temperature (moisture content) in compressed air, ensuring air quality meets industry standards such as ISO 8573.The FM870 online dew point analyzer adopts SIDPH's self-developed capacitive alumina silica mixed dielectric technology, which has high accuracy, rapid response, and high sensitivity. Online monitoring data is output to PLC or other industrial control devices through analog signals.Resistant to high-pressure environments (up to 50 bar). Built in temperature and pressure compensation algorithms ensure accurate and reliable measurement results. Equipped with LCD display screen, data recording and alarm function, supporting 4-20mA/RS485 output, easy to integrate into the control system. Suitable for industries such as pharmaceuticals, electronics, food, and chemicals, it effectively monitors the performance of drying machines and prevents equipment corrosion and product contamination caused by excessive moisture. IP65 protection level, compact structure, easy maintenance, it is the core tool to ensure the dryness of compressed air systems.
FM870Designed for reliable measurement of low dew point (as low as -100 ° C), it is suitable for the semiconductor industry and various industrial applications, such as pure gas, dryers, drying chambers, additive production, and other applications that require high-precision humidity control.
Dew point meter is mainly suitable for detecting moisture in dry gases, including H2, SF6, N2, O2, Ar2, CO2, compressed air, and other gases. It is suitable for measuring moisture in industries such as power, chemical, aviation, metallurgy, and food.

Technical parameters:
When using the FM870 dew point meter to measure the dew point of compressed air, the following precautions should be taken:
Pressure range: Ensure that the selected dew point meter can adapt to the working pressure range of the compressed air system. Select the appropriate pressure range according to practical application needs.
Gas purification: Before conducting dew point measurement, ensure that the compressed air has undergone appropriate purification treatment to remove suspended solids, oil mist, particulate matter, and other impurities. These pollutants may affect the accuracy of measurement results.
Pressure stability: During measurement, ensure the pressure of the compressed air system is stable to avoid sudden changes in pressure affecting the measurement results.
Sampling point selection: Select appropriate sampling points to represent the compressed air in the system. It is usually recommended to sample at the dryer outlet or other critical locations of the system to obtain the most accurate dew point measurement.
Measurement time: Allow sufficient time for the dew point meter to reach a stable state, ensuring the accuracy of the measurement results. Different instruments may require different amounts of time to stabilize.
Instrument calibration: Regularly calibrate the dew point meter to ensure the accuracy of its measurement results. According to the requirements of the instrument, calibrate and adjust it, or contact professional technicians for calibration.
Temperature compensation: Some advanced dew point meters have temperature compensation function, which can automatically correct according to the gas temperature. If using this type of instrument, please ensure the accuracy and stability of the temperature sensor.
Instrument maintenance: Regularly clean and maintain the dew point meter, and carry out maintenance work according to the guidance provided by the manufacturer. This includes cleaning sensors, replacing damaged components, and ensuring the normal operation of the instrument.
