    August 2003 Display and Keypad The PM880 front panel (shown in Figure 1-1 on page 1-2) has a 240 X 200 pixel LCD display, which can show data in either alphanumeric or graphic formats. Below the display, the 25-key keypad enables users to program and operate the PM880. The functions for the various keys are discussed in Chapter 2.

  • Page 15: Probes

    Probes Probes are the part of the system that come into contact with the process flow. The PM880 uses various types of probes to fit the needs of a wide range of applications. The term “probe” includes devices such as moisture sensors and pressure transducers.

  • Page 19: Cabling

    The M and the TF Series probes are connected to the analyzer with a special GE Panametrics shielded cable. Probes can be located up to 600 meters (2,000 feet) from the PM880 (consult GE Panametrics for distances up to 1,200 meters). To measure pressure with a TF probe, the maximum cable length is approximately 152 meters (500 feet).

  • Page 20: The User Program

    August 2003 The User Program On the PM880, users access and control the user program by pressing the Menu key at the bottom of the keypad. This program enables users to enter the necessary probe and calibration data, set up the display, log data, and perform service functions. The meter stores this data in battery-backed RAM.

  • Page 21: Chapter 2: Initial Setup

    August 2003 Chapter 2 Initial Setup The PM880 hygrometer typically functions as part of a complex process system. Before making measurements, you must install batteries, attach a probe, and set it up in a sample system (either a preinstalled sample system or the GE Panametrics optional portable sample system).

  • Page 22: Choosing A Site

    Choosing a Site You should have discussed environmental and installation factors with a GE Panametrics applications engineer or field sales person by the time you receive the PM880. The equipment should be suited to the application and installation site. •...

  • Page 23: Moisture/Temperature Probe Considerations

    Observing these few simple precautions will result in a long and useful probe life. GE Panametrics recommends that probe calibration be checked routinely, at 12-month intervals, or as recommended by our applications engineers for your particular application.
  • Page 24 August 2003 Moisture/Temperature Probe Considerations (cont.) Observe the following environmental precautions. a. Temperature Range The standard probe is operable from -110°C to +70°C (-166°F to 158°F). b. Moisture Condensation Be sure the temperature is at least 10°C higher than the dew/frost point temperature.
  • Page 25 August 2003 Moisture/Temperature Probe Considerations (cont.) e. Long-Term Storage & Operational Stability Sensors are not affected by continuous abrupt humidity changes or damaged by exposure to saturation conditions even when stored. However, you should store probes in their original shipping containers in a clean, dry location. If the probe is saturated during storage, refer to b.

    They may also allow ambient contamination to enter the sample stream. In general, you should use stainless steel material for all wetted parts. Contact the GE Panametrics PCI Division at 1-800-833-9438 (within the USA) or 781-899-2719 (outside the USA) for further instructions.
  • Page 27 The sample system is normally fastened to a metal plate that has four mounting holes. GE Panametrics also provides the sample system in an enclosure if requested. In either case, fasten the sample system plate or enclosure with four bolts — one in each corner.

  • Page 28: Installing The Probes

    Screw the probe in, making sure not to cross thread it. Tighten down securely. Figure 2-2 below shows a typical moisture probe orientation with the probe mounted in a GE Panametrics sample cell. Install moisture probes with different fittings in the appropriate manner.

  • Page 30: Charging And/Or Replacing Batteries

    Charging the Batteries When you receive the PM880, you will need to initially charge the batteries. The batteries must be charged up to 4 to 5 hours to receive the maximum charge, until the red LED goes out. When fully charged, the batteries provide 16 to 24 hours of continuous operation, depending on the probe type and PM880 usage.

  • Page 31: Replacing The Batteries

    (GE Panametrics Part Number 705- 1023). To replace the batteries, remove the rubber boot, open the panel located on the back of the PM880, remove the battery pack, and replace it with a new pack (see Figure 2-4 below).

  • Page 32: Powering On And Off

    IMPORTANT: For CE compliance, the PM880 is classified as a battery-powered device. To turn the PM880 on, press the red button in the upper-right- hand corner of the keypad.

In addition, the instrument has a very rapid response time and it is not affected by changes in fluid temperature or fluid flow rate. If any of the above situations occur, then they are almost always caused by a defect in the sample system.

  • Page 186: Pressure

    4/9/98 Pressure GE Panametrics hygrometers can accurately measure dew points under pressure conditions ranging from vacuums as low as a few microns of mercury up to pressures of 5000 psig. The calibration data supplied with the moisture probe is directly applicable over this entire pressure range, without correction.

    4/9/98 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. Thus, the observed response time to moisture changes is, in general, limited by the response time of the sample system as a whole.

    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 Particulates Note: Molecular sieve particles, organic liquid droplets and oil droplets are typical of this category.

    4/9/98 Non-Conductive Particulates (cont.) On rare occasions, non-conductive particulate material may become lodged under the contact arm of the sensor, creating an open circuit.

    4/9/98 Aluminum Oxide Probe Maintenance Other than periodic calibration checks, little or no routine moisture probe maintenance is required. However, as discussed in the previous 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.

    4/9/98 Solids Applications A. In-Line Measurements GE Panametrics moisture probes may be installed in-line to continuously monitor the drying process of a solid. Install one sensor at the process system inlet to monitor the moisture content of the drying gas and install a second sensor at the process system outlet to monitor the moisture content of the discharged gas.
  • Page 223 If in-line measurements are not practical, then there are two possible laboratory procedures: 1. The unique ability of the GE Panametrics sensor to determine the moisture content of a liquid can be used as follows: a. Using the apparatus shown in Figure A-3, dissolve a known amount of the solids sample in a suitable hydrocarbon liquid.
  • Page 224 4/9/98 B. Laboratory Procedures (cont.) 2. An alternative technique involves driving the moisture from the solids sample by heating: a. The evaporated moisture is directed into a chamber of known volume, which contains a calibrated moisture sensor. b. Convert the measured dew point of the chamber into a water vapor pressure, as discussed earlier in this appendix.
