Figure 209: Initial Plan by UT Research Team for Tower Mounting On May 16, 2013, the URT gathered at Glass City Skyway to mount the Veteran’s sensors on the tower. Horizontal cross-arms were fixed on to the tower at different heights to support the sensors. The UCII crew was divided into three groups to: set up the data loggers inside the tower cabinet, ride a bucket truck and mount the sensors at different elevations, and Upgrade the data acquisition system with new hardware and new sampling rate. Table 45: Summary of VGCS Sensor Installation Trip Crew Position Duties Tower Cabinet Setup white backplanes on shelves. Receive cables from conduit. Connect cables from each sensor to CR1000 and push new program. Reprogram with appropriate sampling rate. Setup IP address for each data logger. On the Tower (Each Sensor Location) Connect vertical cross-arm to tower. Install the gage on the arm. Let the cable down through the conduit. Repeat for all sensors. Old/Main Cabinet Location Upgrade system to CR1000. Reprogram with new scan rate. Setup new IP configuration. MOUNTING TECHNIQUES Different techniques were used to mount the sensors on the tower at different elevations. The ice detector was at the topmost level, followed by solar radiation sensor, rain tipping bucket and leaf wetness sensor. Leaf Wetness Sensor: The leaf wetness sensor was placed flat with the dielectric surface facing upward on the cross arm and firmly attached to it using zip-ties. Figure 210: Leaf Wetness Sensor Zip-tied to Cross-arm Rain Tipping Bucket: The rain bucket was screwed on to a leveling bracket which sat on a vertical pipe. This pipe was mounted on the cross arm using cross-over T joints with for cross arms. OD 1.9” 1.5” IPS
