    Analyzers. Refer service requirements to qualified personnel. Read this entire section before beginning installation of the analyzer. Failure to do so, and/or use of the WDG-V HP Series or WDG-V/S Series Analyzer in a manner not specified in this manual, may impair the protection against fire, electrical shock, and personal injury originally provided by this equipment.

  • Page 36: Unpacking And Inspecting The Equipment

    Open the Remote Calibration Unit (RCU) Enclosure and inspect all interior components for obvious damage and broken/loose parts or fittings. If equipment is damaged, notify the carrier and contact AMETEK Service (https://www.ametekpi.com/customersupport/requestsupport) immediately if parts are missing or damage is found, and to verify if damaged parts will re- quire replacement prior to safely installing and operating the analyzer/equip- ment.

    Installing the Sample Inlet Probe This section includes separate procedures on how to install the Sample Inlet Probe for WDG-V HP Series and WDG-V/S Series Analyzers. Installing the Sample Inlet Probe and Probe Filter (WDG-V HP Series) The sample probe and filter must be attached to the back of the sensor before mounting the sensor to the process.

  • Page 40: Installing The Sample Inlet Probe And Exhaust Tube (Wdg-V/S Series)

    In that case you should mount the analyzer first and then install the probe. 34 | Thermox ® WDG-V HP Series and WDG-V/S Series Analyzers PN 10686-17-5, Rev A...

  • Page 41: Installing The Standard 1/8-Inch Npt Sample Probe (Wdg-V/S Series)

    Installing the Standard 1/8-inch NPT Sample Probe (WDG-V/S Series) Connect a standard 1/8-inch NPT Sample Probe to the analyzer as follows: • If your probe is 4 feet or less, simply thread the probe into the back of the sample probe port on the rear of the analyzer (Figure 7), then install the analyzer.

  • Page 42: Installing The Ceramic Probe Or Long Probe (Wdg-V/S Series)

    4. Thread the ceramic or long probe into the sensor inlet port on the sensor backplate. Do not let the probe hit against the AMETEK-provided pipe nip- ple as you insert the probe into the process stream. If inserting a ceramic probe, you must slowly insert it into a hot process stream to prevent the probe from cracking due to thermal shock.

  • Page 43: Installing The Exhaust Tube

    If installing an exhaust tube, you must connect it to the analyzer be- fore mounting the analyzer to the process stream. An optional stainless steel exhaust tube (AMETEK Part No. 70619KE) is available if an extension to the aspirator exhaust is needed.

    Enclosure door until you first verify that the area has been classified as nonhazardous. There are three (3) different methods to mount a WDG-V HP Series Analyzer to the process gas. Each of these methods is explained in the following pages.
  • Page 45 3. Weld the AMETEK-supplied mounting plate to the process wall. 4. Mount the analyzer to the process as described in the “Mounting the Sen- sor to the Process” section later in this chapter. This method positions the analyzer flush with the process and helps to ensure that the sample gas does not cool below its dewpoint.

  • Page 46: Analyzer Customer-Supplied Mounting Plate With Pipe Attached Pipe Nipple Installation For Wdg-V Hp Series

    1. Weld a short 3-1/2" diameter pipe nipple to the duct and extend through the wall. The shorter the pipe nipple, the better. 2. Insert the AMETEK-supplied pipe nipple (on the end of the mounting plate) into your pipe nipple. If the pipe nipple extends past the inside of the refractory wall on a process which has a gas temperature over 650 °C,...

  • Page 48: Installing The Wdg-V/S Series Analyzer

    Analyzer Flush-to-Process Installation for WDG-V/S Series (Preferred Method) Weld the 7" x 7-5/8" (17.78 cm x 19.37 cm) mounting plate (AMETEK Part No. 70626SE) supplied with the analyzer to the process wall over a 3-3/4" (9.52 cm) diameter hole (Figure 11). Then, bolt the analyzer to the mounting plate. This method positions the analyzer as close to the process as possible and mini- mizes any chance that the sample gas will cool below its dewpoint.

  • Page 49: Analyzer Customer-Supplied Flange Installation For Wdg-V/S Series

    Mount the analyzer to a 3" x 300# customer-supplied flange (Figure 12). In this case, you will not need the AMETEK-supplied mounting plate with attached protective pipe nipple. If you have a different type of flange, AMETEK supplies a number of flange adapters.

  • Page 50: Analyzer Customer-Supplied Pipe Nipple Installation For Wdg-V/S Series

    3. Wrap the nipple with at least 1" (2.54 cm) weatherproof insulation and heat trace it. 4. Bolt the analyzer to the plate. Figure 13. WDG-V/S Series Analyzer customer-supplied pipe nipple installation. 44 | Thermox ® WDG-V HP Series and WDG-V/S Series Analyzers PN 10686-17-5, Rev A...
