CHAPTER 3 INSTALLATION This chapter provides the information you need to: • Mount the HMT140 on a wall or duct • Connect the HMT140 to your network • Review optional mounting accessories M21488EN-C 13
Mounting Mounting Depending on your installation requirements, you may wish to complete the network configuration and setup prior to mounting (see, Chapter 4 Setup and Operation). Note that you can complete the configuration and setup procedures after mounting with a portable PC. Note: To connect the HMT140 to your network and view HMT140 data using viewLinc, you require HMT140 Utility software and an HMT140 Configuration Cable (shipped with viewLinc).
Mounting Figure 2: Mounting Diagram Note: It is strongly recommended that you use all four screws; however, the HMT140 enclosure fastening holes are initially covered with a thin plastic membrane, so less than four screws could be also be used without sacrificing the ingress protection (IP) class of the enclosure. Duct Installation The duct installation kit includes a plastic pipe with a flange (Vaisala part#: 215619).
Mounting See “Probe Assembly with Duct Installation Kit” on page 16 for details. 24 1 L Figure 3: Probe Installation The following numbers refer to Figure 3: 1 Tension screw Distance L can be adjusted and locked in place with the tension screw.
Mounting The following numbers refer to Figure 4: 1 2 3 Probe (HMP110) Duct installation kit Probe cable To assemble the probe: 1 Pass the probe cable through the plastic pipe of the duct 2 installation kit. Connect the probe cable to the HMP110. .
Mounting Figure 6: Drilling specifications Optional Mounting Accessories Probe Mounting Flange The probe mounting flange (Vaisala order code: 226061) is a general purpose mounting flange for 12 mm diameter probes. It can be used to hold the HMP110 probe in a through-wall installation. Note: The coaxial silicone plug that is delivered with the flange is not suitable for use with the probe cable of the HMT140.
Wiring Diagrams Installing the entire probe in the measurement environment prevents heat conduction to the sensor, and is the recommended installation method.
