It can also determine heat stress index which measures how hot it feels when humidity is combined with temperature air movement and radiant heat.
Heat stress wet bulb globe temperature. It takes into account multiple atmospheric variables including. For indoor environments the meter does not use the dry bulb temperature since the globe and the dry bulb should be equal without radiant heat. Temperature humidity wind speed sun angle and cloud cover solar radiation. The heat index and wet bulb globe temperature wbgt are both used to measure environmental temperature.
What is wet bulb globe temperature wbgt. According to the national weather service wet bulb globe temperature wbgt is an apparent measurement used to estimate the most accurate level of heat stress in direct sunlight. The globe temperature is used since it will also detect non solar radiant heat sources if they are present. Temperature humidity wind speed sun angle and cloud cover solar radiation.
The wet bulb globe temperature wbgt index is the most effective means of assessing the effect of heat stress on the human body. It s quicker to refer to it as wbgt but they mean the same thing. The wet bulb globe temperature wbgt is a measure of the heat stress in direct sunlight which takes into account. The equation weighs the wet bulb 70 and the globe 30 of the weighted average.
T w is the wet bulb temperature which indicates humidity t g is the globe temperature which indicates radiant heat t d is the ambient air dry temperature in today s world there are plenty of companies that produce wbgt monitoring devices that can be used to accurately assess wbgt. The wet bulb globe temperature wbgt is an indicator of heat related stress on the human body at work or play in direct sunlight. The ht30 wet bulb globe temperature wbgt measurement considers the effects of temperature humidity and direct or radiant sunlight. Niosh recommends the use of wet bulb globe temperature wbgt to determine the recommended exposure limits rels for acclimatized workers and the recommended alert limits rals for unacclimatized workers in hot environments.
The wbgt index is used to determine flag conditions as a safety. Temperature humidity wind speed sun angle and cloud cover. The wetbulb globe temperature wbgt is a measure of the heat stress in direct sunlight which takes into account.
