Validation of sensors for the determination of humidity in compressed gases
- Five miniaturized sensors based on dew-point, capacitance or resistance measurement were tested for the detection of humidity in compressed gases. The dew-point sensors with optical or dielectric detection of condensation were used at gas pressures up to 3 MPa in dew-point range of -20 to 70°C and show no systematic deviation and an uncertainty of dew-point temperature mostly less than 1 K. The LiCl sensor has also a low uncertainty but exhibit a systematic deviation to higher values of dew-point. Capacitive polymer sensors can indicate also a dew-point, even down to -70 °C and have an uncertainty of about 1 to 2 K. The oxide sensor works in the dew-point range of -10 to 20°C and has a signal what exponential decreases with increasing gas pressure up to 10 MPa. All types of sensor can be applied in compressed gases at least up to 3 MPa, but their different change of sensor signal due to the gas pressure has to be considered.
