    Chapter 1. Installation Chapter 1. Installation Introduction The HygroPro moisture transmitter is a compact, intrinsically safe, loop-powered, 4–20 mA transmitter that provides accurate dew/frost point measurements over a range of –110°C to 20°C (-166°F to 68°F). It features an integrated display and a six-button keypad, and is housed in an IP66/67, NEMA 4X rated enclosure.

  • Page 14: Sample System Guidelines

    Sample System Guidelines The HygroPro transmitter can be installed in a sample system or directly in the process line. However, Panametrics recommends that the transmitter be installed in a sample system to protect the sensor probe from potentially damaging components in the process stream. Figure 2 below shows a typical sample system.

  • Page 15: Mounting The Transmitter

    Mounting the Transmitter CAUTION! If the HygroPro will be installed directly into the process line, consult Panametrics for proper installation instructions and precautions before proceeding. Refer to Figure 3 below and complete the steps on the next page to install the HygroPro transmitter.
  • Page 16 Chapter 1. Installation Note: Do not unscrew and remove the metal desiccant cap from the probe until just prior to installation of the probe in the process. Note: If there is insufficient space to rotate the HygroPro during installation, remove the Replaceable Transducer Element (RTE) from the transmitter, install it in the fitting, then re-install the transmitter display onto the RTE.
