9. diameter globe for a faster response time The temperature of the 2 inch globe is correlated to match that of a 6 inch globe As an option a sensor array with a 6 inch diameter globe is available Dry Bulb Thermometer The dry bulb thermometer measures the ambient air temperature This measurement is used in the outdoor WBGT calculation when a high solar radiant heat load may be present The series of white plates surrounding the sensor shield it from radiant heat 5 Remote Sensors 2 and 3 Remote Sensors 2 8 3 Relative Humidity Sensor A relative humidity sensor is located in a compartment inside of the sensor bar housing Slots in the housing allow air to circulate around the sensor Remote Sensors 2 and 3 The top sensor bar sensor 1 may be removed from the instrument and used through a remote cable Shelter the instrument and remote the sensor bar if the measured environment is expecting heavy rain or if temperatures are above 60 C The sensor 2 and sensor 3 jacks on the side of the instrument allow simultaneous monitoring of up to three sensor arrays using connecting cables Cable lengths of up to two hundred feet 61 meters may be used without a decrease in accuracy provided the environment does not contain strong electromagnetic fields The data from these arrays may be viewed separately or combined into a weighted average WBGT reading per ISO 7243 Change the displayed sensor bar by pressing and releasing the enter key Th
