Measures against dew condensation on metal products! The optimal solution to ensure quality and safety
To maintain the quality and safety of metal products, it is essential to take measures against dew condensation at each stage of production, storage, and distribution.
dew condensation can cause problems such as rust on products, corrosion on equipment, and an unsafe working environment, so prevention is an urgent priority.
Recently, remote monitoring using wireless temperature/humidity systems has been attracting attention, and real-time management of on-site temperature and humidity makes it possible to respond quickly.
The advantages of the wireless temperature/humidity system are as follows:
- Data can be monitored in real time from a remote location such as an office.
- When an alarm occurs, the abnormality can be recognized immediately on the graphic screen or the network monitoring display light.
- memory function makes data management easy and history checking smooth
This article takes a closer look at the need to prevent dew condensation, the limitations of conventional monitoring methods, and the specific benefits of introducing a wireless temperature/humidity system.

The Importance and Risks of Preventing dew condensation
dew condensation on metal products not only reduces product quality, but also causes multifaceted problems such as corrosion of equipment and creating an unsafe working environment.
- Maintaining product quality
Moisture caused by dew condensation can cause rust and shorten the product's lifespan.- Equipment Protection
Dew condensation accelerates corrosion of pipes and mechanical equipment, leading to increased maintenance costs.- Safety in the Work Environment
Slippery floors and wet environments increase the risk of workplace accidents.
Except for the first point, there are other effects besides the product itself, but preventing dew condensation throughout the entire manufacturing process is
This proves to be an extremely important factor.
Conventional monitoring methods and their challenges
Previously, temperature/humidity sensors were installed on-site and workers performed regular visual inspections.
However, these methods had the following problems:
- Lack of real-time performance
Measures can only be taken after dew condensation has occurred, and there is a risk that the damage will worsen.- Human error
Because it relies on regular inspections, oversights can occur.- Lack of standardization
Since the effectiveness of monitoring varies depending on the facility and region, it is difficult to implement uniform measures.
Solutions for remote monitoring using wireless temperature/humidity systems
The wireless temperature/humidity system is an innovative solution to solve traditional problems
Abnormalities in temperature/humidity can be detected instantly, enabling rapid response.
You can grasp the system status even from a remote location, and history management is also easy.
It covers a wide area and obtains accurate data to minimize the risk dew condensation.
It requires little maintenance and can be used for a long period of time.
System specifications example
System Overview
It supports product quality control by monitoring seasonal dew condensation in warehouses and storage areas within factories and preventing rust on metal products.
The MD8000 is used to collect temperature/humidity, and metal product temperature, and CISAS is used to collect, monitor, and notification the data.
CISAS calculates the "dew point temperature," "metal product temperature - dew point temperature," and "dew condensation warning rank," and visualizes the risk of dew condensation.
[Operational Points]
- Regular system inspection and regular calibration of sensors.
- Optimal placement of sensors according to site conditions.
- Strengthening preventive measures through analysis of historical data.
