Accurate humidity measurement despite exposure to volatile organic compounds
Volatile organic compounds (VOC) cause drift in humidity sensors, requiring a removal and resetting of the sensor. The HYT 223 is IST AG’s newest member of the HYT product series and allows for an automatic reset without having to remove the sensor.
(PresseBox) - When measuring humidity in environments with exposure to VOC, a drift occurs which over time causes faulty measurement results. The sensor needs to be removed and reset by heating, which is not only time-consuming, but ultimately amounts to maintenance costs.
Innovative Sensor Technology IST AG has developed a multi-functional digital humidity and temperature module with an integrated micro-heater with excellent long-term stability and which maintains its accuracy long-term with minimal drift. The accuracy at 0 to 50 °C is ± 1.8 % RH at 0-90 % RH and ± 3.0 % RH at 90-100 % RH.
The HYT 223 is a heatable digital humidity sensor with wide humidity and temperature ranges, and thanks to its PTFE membrane filter, it comes with high chemical resistance. The sensor is very stable at high humidity, which makes it suitable for monitoring processes with high humidity, e.g. incubators or greenhouses, or in applications chemicals requiring degassing to avoid drift, like swimming pools, in cheese production or animal farms.
Operating Temperature range: -20 °C to +120 °C
Operating Humidity range: 0 % RH to 100 % RH
Long-term drift humidity/ temperature: < 0.5 % RH/a / < 0.05 K/a
Digital output: I2C protocol
The fully calibrated and temperature compensated sensor is suitable for the moisture analysis from low to high humidity ranges in environments with high exposure to VOC. The HYT 223 contains a micro heating structure which allows for thermal reconditioning. A reconditioning cycle is recommended in challenging atmospheres and conditions. Length and interval required depend on the application environment.
