Moisture measurement in chemicals production and storage

Relative humidity, absolute humidity and temperature measurements for efficient and safe chemicals drying, processing and storage.

In chemical industry, moisture analysis is required for ensuring smooth drying operations such as spray drying or vacuum drying. By measuring accurately relative humidity (RH), absolute humidity, dew point and temperature, chemicals manufacturer can be certain there is no quality deviations in the produced powdered chemicals, the drying process is efficient, and use of energy is optimized.

Moisture monitoring is also needed in storages of chemicals to preserve the quality of the final product and prevent the risk of chemical reaction and explosion. Humidity control is also crucial for preserving hygroscopic substances and preventing powder caking.

Finally, conditions monitoring, and humidity control are required for ensuring safe environment where glove boxes, reaction chambers and vacuum chambers are used.

Vaisala's HUMICAP® and DRYCAP® technologies for improved chemical tolerance

Vaisala HUMICAP® humidity and DRYCAP® dew point sensors both feature good chemical tolerance. For especially demanding applications Vaisala has developed chemical purge function, which helps to maintain measurement performance under chemical exposure. This is a unique feature that helps to correct possible long-term drift of the instruments and extends the required calibration interval in environments where gaseous chemical impurities are present. Hydrocarbon based solvents, cleaning chemicals and sterilizing agents are all chemicals with a tendency to penetrate into the sensor. They all can be driven out using chemical purge.

Vaisala Jade Smart Cloud for real-time data storing and access via cloud

With Vaisala Jade Smart Cloud system you can store the humidity and temperature monitoring data to a cloud in real-time and access it, for example, for reporting purposes. Our cloud solution combines several advanced technologies that make it extremely reliable:

  • Scalability: As a modular system, Jade Smart Cloud can be scaled easily for a variety of purposes. Users can simply set up as many loggers and access points as they need and add more as their needs change. 
  • Cloud storage: All data collected is stored in the cloud, meaning there’s no need to worry about IT infrastructure, security, system maintenance, or setting aside server space for data storage.
  • Extremely good radio connectivity: Jade Smart Cloud’s wireless connectivity is based on LoRa radio technology, which is already widely respected. Vaisala has pushed it even further with modified features to ensure that it meets our customers’ most demanding requirements.
  • Regular firmware updates: Jade Smart Cloud’s software updates automatically, with no action needed from the end user as the new firmware version is installed directly onto the local system from the cloud.
  • Vaisala HUMICAP® sensors: Because the system uses proven HUMICAP sensors, it provides extremely stable and high-quality measurements.
