BlackGlobe Temperature Sensor for
Heat Stress
1. Introduction
The BlackGlobe Temperature Sensor for Heat Stress (BlackGlobe) measure
radiant temperature. This measurement, along with the measurement of
ambient air and wet-bulb temperatures, is used to calculate the wet-bulb globe
temperature (WBGT). The WBGT index combines the effects of temperature,
humidity, radiant heat, and wind into one single index employed to express
environmental heat stress. The measurement of heat stress is important
because 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.
Before installing the BlackGlobe, please study
• Section 2, Cautionary Statements
• Section 3, Initial Inspection
2. Cautionary Statements
• The BlackGlobe is a precision instrument. Please handle it with care.
• The black outer jacket of the cable is Santoprene® rubber. This
compound was chosen for its resistance to temperature extremes, moisture,
and UV degradation. However, this jacket will support combustion in air.
It is rated as slow burning when tested according to U.L. 94 H.B. and will
pass FMVSS302. Local fire codes may preclude its use inside buildings.
• Do not use the BlackGlobe with long lead lengths in an electrically noisy
environment.
3. Initial Inspection
• Upon receipt of the BlackGlobe, inspect the packaging and contents for
damage. File damage claims with the shipping company. Immediately
check package contents against the shipping documentation (see Section
3.1, Ships With List). Contact Campbell Scientific about any
discrepancies.
• The model number and cable length are printed on a label at the
connection end of the cable. Check this information against the shipping
documents to ensure the expected product and cable length are received.
