The following specific topics are covered: • Moisture Monitor Hints • Contaminants •...

  • Page 64: Moisture Monitor Hints

    One of the major advantages of the GE Panametrics hygrometer is that it can be used for in situ measurements (i.e. the sensor element is designed for installation directly within the region to be measured).

  • Page 65: Pressure

    Response Time The response time of the GE Panametrics standard M Series Aluminum Oxide Moisture Sensor is very rapid - a step change of 63% in moisture concentration will be observed in approximately 5 seconds.

  • Page 66: Temperature

    The converse will happen during the cooler evening hours. Flow Rate GE Panametrics hygrometers are unaffected by the fluid flow rate. The moisture probe is not a mass sensor but responds only to water vapor pressure. The moisture probe will operate accurately under both static and dynamic fluid flow conditions.

  • Page 67: Contaminants

    For convenience, the above particulates have been divided into three broad categories. Refer to the appropriate section for a discussion of their affect on the GE Panametrics moisture probe. Non-Conductive Note: Molecular sieve particles, organic liquid droplets and oil Particulates droplets are typical of this category.

  • Page 68: Conductive Particulates

    June 2003 Conductive Particulates Note: Metallic particles, carbon particles and conductive liquid droplets are typical of this category. Since the hygrometer reading is inversely proportional to the impedance of the sensor, a decrease in sensor impedance will cause an increase in the meter reading. Thus, trapped conductive particles across the sensor leads or on the sensor surface, which will decrease the sensor impedance, will cause an erroneously high dew point reading.

  • Page 69: Aluminum Oxide Probe Maintenance

    June 2003 Aluminum Oxide Probe Other than periodic calibration checks, little or no routine moisture probe maintenance is required. However, as discussed in the previous Maintenance section, any electrically conductive contaminant trapped on the aluminum oxide sensor will cause inaccurate moisture measurements. If such a situation develops, return of the moisture probe to the factory for analysis and recalibration is recommended.
