Measure dew point in blanketing atmosphere with Vaisala DRYCAP® sensor technology
Content from Vaisala · retrieved on View the original source
During the plate glass manufacturing process, molten glass is very sensitive to moisture and is typically run under blanketing atmospheres where moisture is carefully monitored. The higher the quality of the glass, the more essential accurate moisture control becomes.
Dew point measurements are often made in harsh conditions with high temperatures and volatile chemical vapors. Due to the unique design of Vaisala’s DRYCAP® sensor, it is immune to most chemical contaminants found to offgas from this process.
DRYCAP is based on two innovations: the proven capacitive thin-film polymer sensor and the auto-calibration function. The sensor is heated at regular intervals during the automated auto-calibration procedure. The humidity and temperature readings are monitored as the sensor cools to ambient temperature, with offset correction compensating for any potential drift. This enables the DRYCAP sensor to deliver accurate measurements in demanding processes such as glass manufacturing, dramatically reducing the need for sensor maintenance.
