However, you may have to enter new reference values if you replace the User Program or make other changes to the meter. Read ppmv, on the Moisture Content scale. Hermetically sealed alarms are available. Gaseous water vapor will actually condense to form liquid water at a higher temperature at the psig pressure than at the 1 atm pressure. Operate the sample system at the lowest possible gas pressure. Between these calibrations, if the aluminum oxide moisture probe becomes contaminated with an electrically conductive liquid, the moisture measurements will be erroneously high. Open both valves and turn on the magnetic stirrer. A blinking E on the left side Open circuit in of the display.

Also, install a proper filter i. Set switch S1 in the appropriate position: Remove the sensor from the hexane or toluene and soak it in the container of distilled water for 10 minutes. The accuracy of the moisture sensor is questioned. At a particular set of operating conditions i. Never connect line voltage or any other power input to the recorder output terminals.

Application of the Hygrometer Since the values of K and CS vary with temperature, the hygrometer measurement and the test sample analysis must be done at the same temperature.

Some of the most frequently encountered problems associated with moisture monitoring sample systems include: Since the addition of the solid may significantly change the saturation value for the solvent, published values should not be used.

On rare occasions, non-conductive particulate material may become lodged under the contact arm of the sensor, creating an open circuit. Assuming the operating conditions are relatively constant, the hygrometer dew point reading can be noted and a solids sample withdrawn for laboratory analysis. As a result, the need for complex sample systems that include extensive piping, manifolds, gas flow regulators and pressure regulators is eliminated or greatly reduced.


Figure below shows a typical probe installed in a sample cell.

Moisture Target Series 5

Gf [s] or [t] until uSEr1 appears on the display. A B Backlight, Display. However, because of severe process conditions and other factors, minor problems may occur from time to time. The dew point of a gas with ppmv of water at psig will be considerably higher than the dew point of a gas with ppmv of water at 1 atm. Excessive equilibrium times would be required with less miscible liquids.

The accuracy of this technique can be checked at any point by withdrawing a sample and performing a Karl Fischer titration. Hermetically sealed alarms are available. Then, the required output adjustment would be calculated as follows: Application of the Hygrometer Introduction.

If high reading persists, the probe is probably shorted and should be returned to the factory for evaluation.

However, no moisture sensor can determine the origin of the measured moisture content. A August Introduction This appendix contains general information about moisture monitoring analyzfr. Therefore, the relative humidity of the system is x 4. Continue stirring until the water is completely blended with the liquid. Connect the sample system inlet to the process and the outlet to the return, using appropriate stainless steel fittings and tubing.

As discussed above, a GE Infrastructure Sensing aluminum oxide probe can be directly immersed in a hydrocarbon liquid to measure the equivalent dew point. Remove the back cover of the enclosure by removing four screws. After you set the switch, slide the main PC board back into the enclosure and fasten the screws on the back cover Connect the recorder output to terminal block TB2 on the back of the MTS 5 as shown in Figure on page Open both valves and turn on the magnetic stirrer.


A-9 Corrosive Gases And Liquids. Proceed to the appropriate section for specific instructions.

To enter new high and low reference values, enter the User2 menu as described on page and proceed as follows unit Press [s] or [t] until rEF appears on the display. Using a straightedge, connect the dew point as measured with the GE Infrastructure Sensing Hygrometer with the known system pressure.

Appendix A, pages A-6 and A Before entering the calibration curve data, make sure the high and low dew points programmed into the MTS 5 match those on the calibration curve see page for instructions. Red Shield Green Figure To perform this task, enter the User2 menu as described pxnametrics page and proceed as follows: Refer to Dew point at the Appendix A, page A-3, for more information. OR An alternative technique involves driving the moisture from the solids sample by heating: One of the major advantages of the GE Infrastructure Sensing hygrometer is that it can analyzeg used for in situ measurements i.

To keep the backlight on all the time, set the backlight timer to 1, minutes. Measure the dew point of the known sample with the GE Infrastructure Sensing hygrometer.

Remove the four clip-on mounting brackets from the unit see Figure on page The current recorder output high value, in the units specified on pageis displayed.
