Cảm biến nhiệt độ Campbell Scientific BLACKGLOBE-L

Overview

The BlackGlobe Temperature Sensor for Heat Stress measures radiant temperature using a thermistor inside a 15.2 cm (6 in.) hollow copper sphere that is painted black. This measurement, along with the measurement of ambient air and wet-bulb temperatures, is used to calculate the wet-bulb globe temperature (WBGT) index. 

Detailed Description

Loss of physical and mental efficiency occurs under definable degrees of heat stress. Severe heat stress can lead to fatigue, exhaustion and possibly even disability or death. The Wet Bulb Globe Temperature Index (WBGT) combines the effects of temperature, humidity, radiant heat, and wind into one single index employed to express environmental heat stress.

Heat stress can be reduced by decreasing the lengths of exposure and decreasing the workload of individuals under heat stress. Factors such as the type of clothing worn, the type of work performed, the psychological effects of stress, and availability of fluids can affect the assessment of heat stress, but these factors are not easily quantified. Environmental factors such as temperature, humidity, and wind are more easily measured to assess heat stress.

A custom cable length will need to be specified when the BlackGlobe is ordered. The maximum suggested cable length is 304 meters (1,000 feet).
