HYT 221 Sensors for Critical Application Areas
Featured Product from Innovative Sensor Technology IST USA Division
The HYT 221 - for critical application areas
The round stainless steel casing can be easily fitted into housing openings and can be sealed against the wall with the use of an O-ring. Combined with the waterproof metal filter, it results into an assembly that is splash water proof and enables a sealed housing construction while providing a high dynamic responsiveness. Precisely calibrated, the HYT 221 delivers an accuracy of ±1.8% rH and ±0.2°C. Like all representatives of the HYT family, the sensor combines the advantages of a precise, capacitive polymer humidity sensor with the high integration density and functionality of an ASIC. The signal processing integrated in the sensor completely processes the measured data and directly delivers the physical parameters of relative humidity and temperature over the I2C compatible interface as digital values. The module is precisely calibrated by the manufacturer and is therefore fully inter-changeable without adjustment.
Both the linearity error as well as the temperature drift are corrected "OnChip" through computation resulting in an outstanding accuracy over a wide range of applications. Due to mechanical robustness, high chemical stability, dew formation resistance as well as excellent long term stability, the typical areas of application are humidity measurement in saunas, applications in outdoor areas or industrial applications in the field of drying systems.
