Humidity Monitoring

June 8, 2023 | Posted By: Degree Controls Inc.

Humidity monitoring is essential to controlling moisture levels in the pharmaceutical industry.

Do you need to know the humidity condition in the air? Do CGMP (Current Good Manufacturing Practice) regulations apply to you? The FH400 airflow sensor allows you to continuously monitor humidity levels in CGMP-compliant production areas, while simultaneously measuring air velocity and air temperature. Excessive moisture in the air can cause pharmaceuticals to become viscous, and very dry air can cause them to crumble. Automatically recording measured humidity levels with the FH400 connected directly to your building management system gives your team the data they need to assess humidity control. Problems in production and storage areas can be identified and addressed before equipment and product quality are affected. FH400 sensor data supports compliance reporting as well.

Humidity monitoring, FH400

The FH400 is designed with a sealed enclosure and conformal coated electronics. It uses three discrete sensing elements to measure air velocity, temperature, and humidity in real-time. Similar to other airflow sensors from Degree Controls, selections for length, air velocity range, and output style are available. When configuring the FH400, customers generally favor analog output over digital communication. 0 – 5 VDC and 0 – 10 VDC analog signals are scalable to sensor data for the 3 variables measured. For humidity monitoring, RH (relative humidity) is measured from 0 – 100%.
