Page 4: Chapter 1 Introduction
Chapter 1 Introduction General Description The THS-3 is a combined analog Temperature and Relative Humidity sensor. Temperature is sensed by an encapsulated thermistor housed in a stainless steel tube. Thermistor contacts are brought directly to the sensor connector for easy temperature measurement. Relative Humidity is measured using a capacitive-type humidity transducer. -

Page 6: Chapter 2 Installation And Maintenance
Ensure you review local regulations prior to installation. In the United States the THS-3 Temperature & Humidity sensor is to be installed on the south side of the mast 4 to 8 feet above ground. The Canadian regulations are to install the sensor on the south side of the mast 1 to 1.3 meters above the ground. - Page 7 Temperature and Humidity Sensor Figure 2-1: Attaching the assembly to the support arm 2. Loosely attach the support arm to the mast or tower with the clamp bolts at the desired sensor height. Ensure the support arm’s “V” is fitted to the pole.

Page 8: Maintenance
Maintenance FTS recommends that the sensor be returned to FTS for a yearly check of the THS-3 sensor’s calibration. Also, FTS recommends that during any site visit a visual check of the THS-3 cable, connector and sensor filter is performed. - Page 9 Temperature and Humidity Sensor 2.3.1 Inspecting and Replacing the Filter To inspect the THS-3 filter, you must first remove the sensor from the housing assembly. a) Remove any cable ties which will prevent the sensor from being removed from the housing being careful not to damage the cable b) Use a 5/8”...

After installation, the sensor should be given a minimum of thirty minutes to acclimatize to a site before data is taken. Configuring the THS-3 Connect the THS-3 to the data logger on the red Temperature and Humidity port. From the data logger’s home page, select the Sensors icon. Figure 3-1: Home Page The next screen (SDI Sensor Mapping) will display the icons of the dedicated sensors which are already added and set up. - Page 11 Temperature and Humidity Sensor The Air Sensor Setup screen will be displayed: Figure 3-3: Edit the fields by pressing on the field box: Sensor: The default name for the sensor is THS. You can change this if desired. Active: This box must be checked in order for the sensor to collect data Temp: This is the air temperature.

Page 12: In-Line Logging
Temperature and Humidity Sensor In-line Logging In order to view and collect data on a variable, it must be logged. In-line Logging provides the user an option to set up simplified Logging and add variables to Current Conditions from the Sensor Setup screen . - Page 13 Temperature and Humidity Sensor Figure 3-5: Regular Logging The Logging intervals screen will be displayed. If there are already logging intervals set up they will be seen here. Logging intervals created through the Data functions, as described here, are displayed in blue. Logging intervals created using the In-line Logging feature are displayed in green. Figure 3-6: Logging Intervals Press the Add icon, then the Edit icon.
